Nobel Controversy: Smith dismisses Gordon claims, heard it all before

Editor's Note: This is part of our ongoing coverage of the 2009 Nobel Prize in Physics. Read more about the Nobel Prize winners themselves, the Bell Labs engineer who patented the CCD imager, and the illustrious history of Bell Labs.

(This was updated on 19 October.)


Did Eugene Gordon give George Smith the idea for the CCD? “Absolutely not,” says Smith. The Nobel Prize winning engineer says Gordon has made such claims before. “Needless to say, I get a little stirred up when I hear them.”

Gordon, Smith's boss at the time, says he gave Smith the concept behind the CCD.

Regarding the Boroughs paper Smith says: “This is a new one on me. He's made other claims before, but not that one.” Because Gordon has made claims against him before, Smith was ready to produce documents (at least, the first page of documents) he says show Gordon's signature under statements that Boyle and Smith invented the CCD.

(The quality of these documents is not so good, but they are mostly readable. They are from the 1970s and also are scans of faxes sent from Boyle's home in Halifax some time ago.)

At first read, these documents are not exactly decisive-none say anything like: “Boyle and Smith invented the CCD. Sincerely, Eugene Gordon”-but they are highly suggestive. (Smith informs me that the word invent would probably not be used before the patent is granted, anyway. Instead inventors would be called "originators.")

In a 6 November 1969 memo to Bell Labs patent lawyers from Gordon using the words "recent ideas by Boyle-Smith" with regard to the CCD. A memo dated the day before says that "W.S. Boyle and G.E. Smith described a technique [the CCD]". A third dated 23 October 1969 is also to a patent lawyer, but makes no statement that Smith and Boyle (or anyone in particular) are the inventors (or originators), merely that if the lawyer needs more information he should contact Smith and Boyle.

However, Smith calls the October letter the most decisive, because it is the original patent submission regarding the CCD. I'm following up to find out if there's some patent-speak meaning to being named in that section.

The memos are also fascinating in their own right, because two of them  focus on the idea of using a CCD as a display device rather than as an imager—an idea Smith credits Gordon with.

After dismissing Gordon's claims, Smith walked me through the invention of the CCD as he remembers it. The way he tells it, it's origins were strongly tied to the desire to build a better bubble memory. Sailing buddies Smith and Boyle worked in Bell Labs semiconductor division at the time, with Boyle in charge. Magnetic bubble memory was under development by a different division and “was a very hot item at the time.” Smith recalls Boyle worrying to Smith that funding for the semiconductor division would be diverted to magnetic bubble memory unless they could come up with a competing concept.

What followed was their magical afternoon's work. “A lot of people work for years and year and it never works out,” says Smith. “There's a certain amount of luck involved.”

Nobel Controversy: Eugene Gordon Claims He Gave Smith The Idea for the CCD

Editor's Note: This is part of our ongoing coverage of the 2009 Nobel Prize in Physics. Read more about the Nobel Prize winners themselves, the Bell Labs engineer who patented the CCD imager, and the illustrious history of Bell Labs.

IEEE Fellow and CCD camera chip inventor Mike Tompsett has already called into question the validity of Smith’s and Boyle’s claims to this year’s Nobel Prize in Physics, now his former Bell Labs boss, IEEE Fellow and Edison Medal Recipient Eugene Gordon, is backing Tompsett’s position and striking even deeper at Boyle’s and Smith’s contributions to as the Nobel Prize committee called it “the invention of an imaging semiconductor circuit—the CCD.”

“This is an outrage,” says Gordon. Tompsett invented, designed and built the first CCD camera, he says. “Smith had little to do with it. Boyle had nothing to do with it.”

What’s more, in a wide-ranging telephone interview Friday, Gordon told me that he gave Smith the concept behind the CCD, even going so far as to hand him an article by other researchers at Burroughs describing a similar shift register concept for a display device, before “sending him off to work out the numbers.”

The Borroughs paper described a shift register for moving a spot of light based on a three-phase clock. When combined with what Gordon’s group had already learned developing a silicon-diode-based video camera target, there was no great leap of logic to go from that idea to the CCD, he says. “We already knew about storing charge in the space charge gap between the oxide layer and undepleted semiconductor substrate. In that region you can move accumulated or stored charge many centimeters,” he says. All one had to do is set up voltages in a phased clock format to move the charge along “There was nothing to it except the numerical details.”

Smith worked out those details with the man who was Gordon’s boss at the time, Willard Boyle. And the two patented a CCD intended as a kind of bubble memory. Gordon’s name was left off the patent, without his knowledge.

“I had a fit, but there was no point in fighting my boss or destroying the patent for Bell Labs,” says Gordon. “That was just one more invention. I have a hundred patents myself.”

Gordon didn’t talk publicly about the events surrounding the invention for many years, while Boyle and Smith’s standing solidified. During the 1970s he was busy developing the electron beam photolithography mask maker still used in IC fabrication, and in the early 1980s he worked on the semiconductor lasers needed for transoceanic communications. Moreover, he could not speak about the CCD because he was advising Toshiba in their legal battle with Fairchild Semiconductor regarding the technology.

Long retired from Bell Labs, today, Gordon is the CEO of medical device firm Germgard Lighting, in Dover, N. J. It’s an “exciting” time for the business, which makes sterilization equipment to prevent hospital acquired infections, says Gordon.  So last week was “not as upsetting as you might think” for him.

So who should have gotten the Nobel, in Gordon’s opinion?

“It really shouldn’t be a physics award,” he says “Most of the work has been in electrical engineering. There’s no fundamental physics.”

If it had to go to someone for the CCD, it should have gone to Mike Tompsett alone, Gordon suggests.

“The whole thing is an outrage. But such outrages are perpetrated all the time.”

IEEE Spectrum hopes to be speaking with Willard Boyle and George Smith soon. Stay tuned.

Nobel Controversy: A Portrait of Bell Labs in the Mid-1960s

Editor's Note: This is part of our ongoing coverage of the 2009 Nobel Prize in Physics. Former Bell Labs engineer Eugene Gordon claims he gave George Smith the idea for the CCD. Read more about the Nobel Prize winners themselves, the Bell Labs engineer who patented the CCD imager, and the illustrious history of Bell Labs.

Gordon gave me some background on what was happening at Bell Labs at the time, that puts the invention in context:

In the mid-1960s, AT&T wanted to move from providing what’s called plain old telephone service (POTS) to offering businesses network services. The Federal Communications Commission, Gordon recalls, turned them down. AT&T’s plan B was to come up with an offering that would give them a back door into network services. They’d make a video telephone system; claim that it was merely an extended telephone service, which would be allowed by FCC, and sneak in broadband network services, because the Picture phone required broadband lines. The new service was called PANS (Picturephone and network services). Julius Molnar was the architect and he was brilliant.

The camera tubes of the day worked fine in television studios, but the uncontrolled lighting in an office environment easily blinded them. (The technology’s amorphous antimony trisulfide imaging targets were the problem.) Gordon says that he was given the responsibility to develop a camera tube that would not have the bright light burn-in problem of conventional vidicons. In early 1967 he had an idea for a silicon diode array picture camera tube that should do the trick.

Nobel nominee Willard Boyle, who was not his boss at the time, “crapped all over the idea and refused to help even though he had the lab and people who could build it,” he says. But Gordon, working through another part of Bell Labs, persevered.  He and his team had a product that went into manufacture in 1969. (One of the tubes was used to record the Moon landing that year, because it was impervious to the bright sunlight that had ruined other Apollo camera tubes.)

Gordon says he gave Smith the shift register idea following a gathering of the camera tube team Gordon had called to congratulate everyone on moving the camera tube on to manufacturing at Western Electric. “If Picturephone had been a success,” says Gordon. “The camera tube would have been replaced by Tompsett’s CCD camera.”

Sensor Nation, UK Style

At the time of the July 2005 London bombings, the average Londoner was on camera an average of 300 times a day. That didn't prevent an attack, of course. Surveillance cameras — the UK had an estimated 4.2 million of them in 2005 — can help the police solve a crime after it's committed, but no one is looking at them in real time.

A organization named Internet Eyes would change that. It has developed a scheme that would allow ordinary citizens to watch CCTV (closed-circuit television) video streams and sound an alarm when they see things that are, well, alarming. Internet Eyes holds out a reward of £1000.

According to the BBC report that broke the story, today London has "one camera per 14 people" and yet the police have "estimated that in 2008 just one crime was solved per thousand CCTV cameras in the capital. The deficit was partly blamed on officers not being able to make the best use of the many thousands of hours of video generated by CCTV."

It's hard to imagine the Internet Eyes program, which is slated to begin next month in Stratford-upon-Avon, will do much to improve that. While news reports make it sound as if all you have to do is see a crime and report it to collect your £1000, the reality is a lot more complicated and a lot less lucrative.

Viewers are anonymously monitoring random video feeds streamed from privately owned establishments. At no time can Viewers designate or control the video feeds they receive and the locations of the feeds are not disclosed.

The instant a Viewer monitors an event, an alert can be sent directly to the owner of that live camera feed. The alert is sent along with a screen grab, identifying the image you have observed. Only the first alert received by the camera owner is accepted.

The camera owner will then feedback (rate) the result of the alert. Their feedback is converted into points and entered into a Viewers monthly league table. At the end of each month the highest scoring Viewer will receive the reward money; this could be split in the event of a tie.

Viewers register for free with no recurring fees. Each Viewer has 3 x alerts per month allocated to their account for free. Viewers are able to ‘top up’ their alerts through PayPal if they so desire. The free allocations of alerts are limited to prevent system abuse.

So, for one thing, you don't get to choose your feed. Even if you would probably be a more attentive viewer viewing your own neighborhood or a favorite store, you probably will never get that chance. Then, your success depends on the utility rating the camera owner gives to the alert you send — that, plus an opaque points program. Finally, only a single thousand-pound prize is awarded, no matter how many crimes are "solved" by CCTV alarms that month. (Oh, and having to pay for your own alarms after the first three — nice touch. Still, people pay for their votes on American Idol, without any prospect of an award, so maybe they'll pay to play here as well.)

"Solved" is in quotes because it's not clear what it means for a crime to be solved by a CCTV camera. Back in August, privacy expert and security entrepreneur Bruce Schneier noted,

To me, the crime has to have been unsolvable without the cameras. Repeatedly I see pro-camera lobbyists pointing to the surveillance-camera images that identified the 7/7 London Transport bombers, but it is obvious that they would have been identified even without the cameras.

Then there's the question of how well people will assess that a crime is being committed by seeing a few seconds of grainy video stream by their eyes. Football referees often can't determine that a facemask was grabbed, or that a foot stepped out of bounds, when they watch higher quality video streams than those of the average street camera.

The BBC report noted that crimes aren't noticed in real time today because "viewing hours of mostly tedious and often poor quality images is a lengthy and unpopular job." If that's true when people who are doing it receive a regular paycheck, does it get any less tedious when done in the hope of a windfall hardly more likely than winning the lottery? (Still, people pay good money to engage in the same repetitive motions that factory workers have complained about for decades, in the hope of hitting a slot-machine jackpot.)

If the program is unsuccessful, few people will be watching. but if the program is successful, will the camera owners, and ultimately the police, have enough staff on hand to evaluate an alarm quickly enough to apprehend a suspect at the scene of the crime? It seems unlikely. The bottom line is that probably some people will watch the video streams, the police will be alerted to a couple of crimes, and Londoners' privacy will continue to erode.

Exactly one year before the London bombings, Spectrum published a special report entitled "Sensor Nation." In an article entitled "We Like to Watch," my colleague Harry Goldstein presciently wrote,

For entertainment, we gather in front of the tube for mass-mediated group therapy sessions called reality shows. Hundreds of millions of us around the globe tune in to watch people who eagerly endure excruciating plastic surgery; stab each other in the back for a chance to work for Donald Trump; or wolf down sea worms, cockroaches, and worse to survive on a desert island. For Generation Y, "Big Brother" is a reality television show, where, for a chance at winning half a million dollars, contestants volunteer to be cooped up in a house with total strangers and have their most private moments broadcast to a hungry audience.

It's not hard to imagine a near future of reciprocal transparency when all of us are watched and can watch right back. We're halfway there.

History's First Draft

The eyes of the world have moved to U.S. President Obama's surprising Nobel Peace Prize, but the controversies over the Physics prize just keep coming. And it's not just limited to CCD. As my colleague Sue Karlin pointed out to me in an e-mail, an Indian news site has raised questions about fiber optics.

We at Spectrum received our fair share of letters and comments about the half of the prize that went for the charge-coupled device. Our initial article "CCD Camera Chip Pioneers Share Nobel" by contributor Neil Savage led to a fruitful conversation between news editor, Sam Moore, and Michael F. Tompsett, an IEEE Fellow and one-time colleague of newly-minted Nobelists Boyle and Smith ("Nobel Controversy: Former Bell Labs Employee Says He Invented the CCD Imager") as well as a further discussion between Savage and Carlo Sequin, yet another Bell Labs CCD researcher ("Nobel Controversy: Who Deserves Credit for Inventing the CCD?").

Yesterday, published an exhaustive compendium of Nobel Prizes that arguably should have gone to Indian physicists, including:

. Jagadish Chandra Bose (wireless signaling before Marconi as well as anticipating the 'n' and 'p' type semiconductors);

. Satyendranath Bose (Bose-Einstein statistics);

. G N Ramachandran (bio-molecular structures, especially the triple helical structure of collagen); and

. E C George Sudarshan (quantum optics);

Which brings us to this week and "How India missed another Nobel Prize":

What the Academy omitted to note was that Moga, Punjab-born Narinder Singh Kapany, widely considered the Father of Fibre Optics, and, in this capacity, featured in a 1999 Fortune magazine article on the 'Unsung Heroes of the 20th Century', had far the stronger claim.
Charles Kao in a 1996 paper put forward the idea of using glass fibres for communication using light; he tirelessly evangelised it and fully deserves a share of the Prize. However, the fact remains that it was Kapany who first demonstrated successfully that light can be transmitted through bent glass fibres during his doctoral work at the Imperial College of Science in London in the early fifties, and published the findings in a paper in Nature in 1954.

The article is written by Shivanand Kanavi , who, according to his blog bio, is a theoretical physicist cum academic cum economic consultant cum business journalist. He's the author of a book, Sand to Silicon: The Amazing Story of Digital Technology, which he quotes from in making the case that Kapany deserves half of the half-prize that went for fiber optics.

Narinder Singh Kapany recounted to the author, "When I was a high school student at Dehradun in the beautiful foothills of the Himalayas, it occurred to me that light need not travel in a straight line, that it could be bent. I carried the idea to college. Actually it was not an idea but the statement of a problem. When I worked in the ordnance factory in Dehradun after my graduation, I tried using right-angled prisms to bend light.
"However, when I went to London to study at the Imperial College and started working on my thesis, my advisor, Dr Hopkins, suggested that I try glass cylinders instead of prisms. So I thought of a bundle of thin glass fibres, which could be bent easily. Initially my primary interest was to use them in medical instruments for looking inside the human body. The broad potential of optic fibres did not dawn on me till 1955. It was then that I coined the term fibre optics."

Giving credit where it is due is hard. Kanavi does a good job of tracing the idea of bending light all the way back to the 1840s. In Savage's follow-up article Carlo Sequin teases out the contributions of six different Bell Labs researchers.

If journalism is, as the journalist Phil Graham once said, the "first rough draft of history," then the Nobel committee is in the uncomfortable position in between: trying to do a journalist's job with the full weight of historical accuracy on its shoulders. And so the current controversies have a silver lining: we get to read about the contributions of the many other brilliant researchers who contributed to these marvelous ideas and life-improving technologies.


Nobel Controversy: Former Bell Labs Employee Says He Invented the CCD Imager

Who patented the first digital imager? Michael F. Tompsett says he did. (Although the signal is only digital after it’s gone through the video analog-to-digital converter chip that he also invented.)

Did Willard Boyle and George Smith invent the charge coupled device? “Their name is on the patent,” says IEEE Fellow and former Bell Labs colleague of the pair of new Nobel Prize Winners,“but all patents are a product of their time and others may have had an input.”

But did they invent “an imaging semiconductor circuit” as the Nobel citation goes? No, he says. “That was me.”

The CCD that Boyle and Smith invented was not for imaging, it was intended as a memory circuit. According to both Tompsett and the United States Patent Office, it was Tompsett who invented the imager that first demonstrated the electronic photography and video in use today. Tompsett is the sole inventor listed on United States Patent Number 4,085,456 “Charge transfer imaging devices.” The patent covers two, subtly different, types of imagers one of which is the CCD imager.

“All the imaging and reduction to practice was me,” says the physicist who in the 1970s ran Bell Labs’ CCD group, which developed TV resolution imagers.

Tompsett had been an imaging guy even before he arrived at Bell Labs. In England he invented an infrared camera tube, which was subsequently developedt, and used by the U.S. and British militaries, fire brigades and search and rescue teams, and won a Queen’s Award in Britain, he says. He also invented another silicon-imager that “never saw the light of day” because it was quickly eclipsed by the CCD. And he also came up with a solid-state thermal imager that’s now been commercialized for night vision.

But imaging isn’t his only important contribution. He also developed a technology that was key to growing the gallium arsenide layers of early LEDs and is still in use today. He invented the first solid-state MOS modem and a video analog-to-digital converter chip that is now manufactured by the millions. He now works on healthcare software as founder of Theramanager, in New Providence, N.J.

“I don’t have to hang my reputation [on the CCD imager]” he says, but “it would be nice to at least share the credit.”

You’d expect this to be a galling time for him. Even the picture he’s confronted with in newspapers and this web site is an affront: a staged photo of Boyle and Smith manipulating a camera in 1974. Neither Nobelist was involved with Bell Labs imaging chip work at the time, and Tompsett himself built the camera they are supposedly working with. He was keen to acknowledge the contributions of Ed Zimany and the rest of his group, particularly Carlo Sequin who joined Bell Labs 9 months after the invention and helped refine the imaging chips. Together, Tompsett and Sequin also wrote the first book on CCDs.

But talking to him the morning of 8 October, he seems more concerned with technical inaccuracy in an IEEE Spectrum article than his place in history. With regard to getting a Nobel Prize he says: “I hadn’t seriously thought about myself.”

“You’re not going to change [who wins] the Nobel,” he says. However, he does believe the citation should be corrected.

Nobel Controversy: Who Deserves Credit for Inventing the CCD?

Editor's Note: This is part of our ongoing coverage of the 2009 Nobel Prize in Physics. Read more about the Nobel Prize winners themselves, the Bell Labs engineer who patented the CCD imager, and the illustrious history of Bell Labs.

So who deserves the accolades for inventing the charge-coupled device? "It depends on what you're celebrating," says Carlo Sequin, who joined the team at Bell Labs developing the CCD a few months after the project began.

"My initial assumption was the Nobel in physics goes to fundamental concepts," says Sequin, now a professor of electrical engineering and computer science at the University of California, Berkeley. "If the fundamental concept was the charge transfer principle, then that goes to [Willard] Boyle and [George] Smith, and maybe Gene Gordon."

But while Boyle and Smith, who were initially trying to design something analogous to magnetic bubble memory for computers in silicon, sketched out the charge transfer concept, they were not the ones who actually built the CCD, Sequin says.

"If we try to find out who made the first practical image sensor, credit would go to Mike Tompsett, possibly [Gilbert] Amelio," he says.

The concept for the CCD was that one could build a potential well in silicon by creating a capacitor out of silicon, silicon oxide, and a metal electrode. Light striking the silicon would be absorbed and would create an electron, which would travel to the well. By applying alternating voltages, you could then moves the accumulated charges from one well to the next until they reached the edge of the chip, where the amount of the charge would reveal the intensity of the light striking each well. 

In the first design, as Sequin describes it, rows of pixels were lined up in columns, and the charges would move down the columns, from one row to the next, until they were read out in a register at the bottom. This design meant the device would take an exposure, close a shutter, move the charges down one row, and then open the shutter for the next exposure. That meant that every other frame would be spent moving the charge.

Tompsett solved the issue with the frame transfer principle. "He came up with the idea, why not double the size of that image sensor," Sequin says. Only half of the sensor would be exposed, and then the next frame of exposure would be taken while the charge was being moved. "As far as I know, he has the patent on it and he is the sole author of it, and it was his idea," Sequin says.

He says others, including himself, contributed to the development of the CCD. Amelio made the first 8 x 8 pixel chip. Sequin was heavily involved in turning that into a 128 x 128 pixel array. Walter Bertram came up with the idea of building the chip with three layers of polysilicon replacing metal as the electrodes. Since they're transparent, they could be deposited on top of the chip without blocking the incoming light. Putting them in different layers prevented them from shorting out in a way that would destroy the whole device; at most you'd lose a pixel or a column.

Sequin says two technical associates, Edward Zimany and William McNamara, were also heavily involved in developing a practical CCD. "It was six engineers who took a very fundamental principle and really made a practical thing of it." He likens Boyle and Smith to sperm donors, providing the seed of the idea, while the others were midwives and mothers who nurtured it into reality.

But the credit for the ubiquity of CCD-based cameras may belong overseas, he says. Bell Labs, which had been focused on creating a picture phone, eventually dropped the idea as impractical and stopped developing CCDs, Sequin says. Fairchild Semiconductor took up the challenge for a while, but also let it go. "Everything lay kind of dormant for another 10 years, until the Japanese picked it up," Sequin says. It took Japanese researchers at Sony and other places another five years to perfect the device. "The Americans dropped the ball," he says.

Energy-Efficient Appliances With Minds Of Their Own

Ten residences now under construction in Masdar City, Abu Dhabi, will be getting home appliances—refrigerators, cooktops, and clothes washers/dryers—with minds of their own. These appliances will be talking to the electric grid and the grid will talk back. Based on what they’re hearing, the appliances will adjust their behavior, with the goal of minimizing their demands at peak energy times and therefore saving their owners money. It’s an experiment designed cooperatively by Masdar, an Abu Dhabi based renewable energy company, and GE Consumer & Industrial. Good for the environment, good for the pocketbook, all good, right?

Uh, maybe. Unless I imagine myself as the homeowner in the midst of one of these supersmart homes, trying to inject myself into the dialog.

Grid, “energy prices are up.”

Refrigerator, “OK, raising internal temperature”

Me, low on ice and expecting guests for dinner, “Uh, does this mean I have to drive to the store and buy ice?”

Grid, “energy prices will drop at 11 pm”

Clothes dryer, “drying cycle paused until 11:05”

Child, “Mom, what do you mean my soccer uniform is wet? I need it now!”

GE does envision an override button, that is, the appliances will respond automatically, but if you happen to notice that the water you put on for pasta has stopped boiling, you can hit an override button. It’s highly unlikely, however, that I’d notice things weren’t going as expected until the guests arrived/the soccer game was about to start/I had called the family to dinner.

So I’d like to add one little tiny feature to this new technology—ask permission first. Text me, tweet me, or send me a message on Facebook—it shouldn’t be too hard in the midst of all this other communication these appliances will be doing to make sure they simply say please.

Long Live Bell Labs

It didn't take long for Wikipedia's Bell Labs entry to be updated to include a seventh Nobel Prize for the storied organization.

1937 Clinton J. Davisson (the wave nature of matter)
1956 John Bardeen, Walter H. Brattain, and William Shockley (transistors)
1977 Philip W. Anderson (electronic structure of glass)
1978 Arno A. Penzias and Robert W. Wilson (cosmic microwave background radiation)
1997 Steven Chu (cooling and trapping atoms)
1998 Horst Stormer, Robert Laughlin, and Daniel Tsui (fractional quantum Hall effect)
2009 Willard S. Boyle, George E. Smith (CCD)

The first six are included in a memorable and entertaining video that the PR department at Lucent Technologies produced during the dot-com bubble, when Lucent and the rest of the telecommunications world was riding high. (It didn't take long for Lucent to be brought down low by the corresponding bust, and right around the time the next bubble was at its height, it was bought by Alcatel.)

The digital camera, among many other innovations, couldn't have happened without CCD (though a lot of them use CMOS these days). The seminal, if not the first, digital camera was based around Kodak's 1986 KAF-1300 Image Sensor, which made Spectrum's list of 25 Microchips That Shook the World."

Kodak's DCS 100 cost about $13 000 (in 1986 dollars), but digital cameras are so cheap and ubiquitious these days that this month's Spectrum do-it-yourself project, a Google Street Maps-like camera array, can use eight of them (and set you back a mere $200 for all of them).

As the 2009 prize shows, Bell Labs' innovations have long outlived the original AT&T and Lucent, an idea that was driven home by technology historian Michael Riordan in a July 2005 Spectrum feature, "The End of AT&T: Ma Bell may be gone, but its innovations are everywhere."

Spectrum's coverage of Bell Labs is too sprawling to offer in its totality, but the above list of Bell Labs' Nobel Prizes wouldn't be complete without the one that got away, memorably described in another Riordan feature, "How Bell Labs Missed the Microchip."

A trip down this particular memory lane also wouldn't be complete without at least one reflection from one-time Bell Labs executive and all-time Spectrum columnist, Bob Lucky: "When Giants Walked the Earth."

Congratulations, Willard Boyle and George Smith. And thank you, Bell Labs. May we somehow, somewhere, someday see another such engine of innovation.


Back In The Clear: Airport Security Service To Resume Operations

Today the New York Times reports that Clear, a company that advertised itself as letting you sail through the security line, is coming back. The company, which died of unknown causes back in June, could resume operations by the “holidays.”

Danny Sullivan at was a believer:

Clear, or Fly Clear as it was sometimes known, allowed people to bypass regular security at some airports for an annual fee. I’ve been a regular user since it started. In fact, I was probably one of the program’s most successful affiliates. I’d written about it from an early point, and so many people used my code to get an extra month (and giving me one in the process) that my card was good through 2064.

Clear evolved from the Transportation Security Administration's Registered Traveler program, which lets companies establish exclusive security lines at airports. Verified Identity Pass, Inc., Clear's parent company, gobbled up the largest market share with 18 of the 21 airports with reserved security lines. Lockheed Martin is the systems intregrator, which I assume means they transistioned the technology out of DHS? Gave Clear lots of money? Who knows what's what in the Homeland Security sausage factory. But I digress.

I was getting all excited about maybe shelling out the $199 for a Clear card, but the more I read, the less I understand.

First off, the Clear card merely lets you cut in front of others in line. It does not let you skip the shoes-and-baggie part. According to one experienced Clear user in the techcrunch comments section, Clear doesn't mean you can board with more than the prescribed 3-1-1:

Just so folks understand – you didn’t get to skip the security “experience”. You simply had priotity access to the checkpoint itself. Still had to remove your shoes, take off your coat, your 3-1-1 plastic bag, laptop out, etc.

So are you "clear" or aren’t you? Now that they have your fingerprints and eye-scans in a database, you get to skip the line, but you’re not so verified that they’d have confidence in you not to smuggle a bomb into your laptop or face cream? And why do you need to show your card if you're also swiping a fingerprint at the kiosk and showing a government-issued ID? For all that, you don't even get to bring an extra ounce of shampoo.

OK, so even if the only benefit is skipping the 50-minute line at Dulles (shudder), I understand the $199 fee. I’d be willing to shell out some cash and my digital identifiers if I could avoid having to remove my shoes, take out my laptop, take out A/V equipment, take off my coat, place my pathetic baggie into a separate bin (god I’m exhausted just thinking about it). But why do we need fingerprints and iris scans on top of the $199 to slip through security slightly faster than a 1K Platinum Global Elite Demiurge Ubermensch?

The more I think about it, the more paranoid it makes me. I realize that there’s only so much privacy you can realistically expect from now on. Even if I don’t cough up my finger- and eye-prints, my online medical records will still be stolen, and if they’re not online, some enterprising hobo will still find them in the trash can out back of the doctor’s office. And for all you off-the-grid militiamen out there, cancelling your doctors appointments won’t help either: In 2006, USA Today reported that 87 percent of Americans could be identified by records listing solely their birthdate, gender and ZIP code. The only thing that makes me feel better is that there is still safety in numbers.

So now for my questions to you, dear reader.

1) Do any Spectrum Online readers have Clear memberships? Is it worth it to you? How long did the fingerprint- and eye-scan process take? Was it convenient, or did you have to schlep to an anonymous office park in McLean, Virginia?

2) Is my contention reasonable: that in an age where everyone is online and catastrophically oversharing, the information pool is so huge and overwhelming that the probability of MY information being stolen is statistically insignificant?

3) In terms of airport security bypassing systems (like the UK’s Iris Recognition Immigration System (IRIS), CLEAR and FLO) do you prefer a card, or an IRIS-like system where you can forget the card and the picture ID and instead go into a small room where you look into a mirror and your eye is scanned and your eye is the only ID you need? What’s the word on laser scarring on the inside of your retina?
