Embedding Iris Watermarking in Photos
Canon has filed a patent on embedding an iris scan of the photographer in the metadata of photographs, presumably secured with a digital signature.
Improvements in Face Recognition
Ignore the laughable “100% accurate” claim; this is an interesting idea:
Mike Burton, Professor of Psychology at Glasgow, and lecturer Rob Jenkins say they achieved their hugely-improved results by eliminating the variable effects of age, hairstyle, expression, lighting, different camera equipment etc. This was done by producing a composite “average face” for a person, synthesised from twenty different pictures across a range of ages, lighting and so on.
Not useful when you only have one grainy photograph of your target, but interesting research nonetheless.
Cameras in the New York City Subways
An update:
New York City’s plan to secure its subways with a next-generation surveillance network is getting more expensive by the second, and slipping further and further behind schedule. A new report by the New York State Comptroller’s office reveals that “the cost of the electronic security program has grown from $265 million to $450 million, an increase of $185 million or 70 percent.” An August 2008 deadline has been pushed back to December 2009, and further delays may be just ahead.

I’ve spent the last few months, on and off, reporting on New York’s counter-terror programs for the magazine. One major problem with the subway surveillance program has been wedging a modern security network into a 5,000 square-mile system that recently celebrated its hundredth birthday. Getting the power and air-conditioning needed for the cameras’ servers has been a nightmare. In many stations, there’s literally no place to put the things. Plus, the ceilings in most of the subway stations are only nine feet high, and there are columns every few yards. Which makes it very hard to get a good look at the passengers.
How Well "See Something, Say Something" Actually Works
I’ve written about the “War on the Unexpected,” and how normal people can’t figure out what’s an actual threat and what isn’t:
All they know is that something makes them uneasy, usually based on fear, media hype, or just something being different.

If you ask amateurs to act as front-line security personnel, you shouldn’t be surprised when you get amateur security.
Yesterday The New York Times wrote about New York City’s campaign:
Now, an overview of police data relating to calls to the hot line over the past two years reveals the answer and provides a unique snapshot of post-9/11 New York, part paranoia and part well-founded caution. Indeed, no terrorists were arrested, but a wide spectrum of other activity was reported.
[…]
In all, the hot line received 8,999 calls in 2006, including calls that were transferred from 911 and the 311 help line, Mr. Browne said. They included a significant number of calls about suspicious packages, many in the transit system. Most involved backpacks, briefcases or other items accidentally left behind by their owners. None of them, Mr. Browne said, were bombs.
There were, however, 816 calls to the hot line in 2006 that were deemed serious enough to require investigation by the department’s intelligence division or its joint terrorism task force with the F.B.I. Mr. Browne said that 109 of those calls had a connection to the transit system and included reports of suspicious people in tunnels and yards, and of people taking pictures of the tracks.
The hot line received many more calls in 2007, possibly because of the authority’s advertising campaign, Mr. Browne said. Through early December, the counterterrorism hot line received 13,473 calls, with 644 of those meriting investigation. Of that group, 45 calls were transit related.
Then there were the 11 calls about people counting.
Mr. Browne said several callers reported seeing men clicking hand-held counting devices while riding on subway trains or waiting on platforms.
The callers said that the men appeared to be Muslims and that they seemed to be counting the number of people boarding subway trains or the number of trains passing through a station. They feared the men might be collecting data to maximize the casualties in a terror attack.
But when the police looked into the claims, they determined that the men were counting prayers with the devices, essentially a modern version of rosary beads.
None of those calls led to arrests, but several others did. At least three calls resulted in arrests for trying to sell false identification, including driver’s licenses and Social Security cards. One informer told the police about a Staten Island man who was later found to have a cache of firearms. A Queens man was charged with having an illegal gun and with unlawful dealing in fireworks.
A Brooklyn man was charged with making anti-Semitic threats against his landlord and threatening to use sarin gas on him. At least two men arrested on tips from the hot line were turned over to immigration officials for deportation, Mr. Browne said.
And as long as we’re on the topic, read about the couple branded as terrorists in the UK for taking photographs in a mall. And this about a rail fan being branded a terrorist for trying to film a train. (Note that the member of the train’s crew was trying to incite the other passengers to do something about the filmer.) And about this Icelandic woman’s experience with U.S. customs because she overstayed a visa in 1995.
And lastly, this funny piece of (I trust) fiction.
Remember that every one of these incidents requires police resources to investigate, resources that almost certainly could be better spent keeping us actually safe.
Secretly Recording Interrogations
It’s getting easier to watch the watchers:
A teen suspect’s snap decision to secretly record his interrogation with an MP3 player has resulted in a perjury case against a veteran detective and a plea deal for the teen.
Unaware of the recording, Detective Christopher Perino insisted under oath at a trial in April that suspect Erik Crespo wasn’t questioned about a shooting in the Bronx.
But the defense confronted the detective with a transcript it said proved he had spent more than an hour unsuccessfully trying to persuade Crespo to confess.
Perino was arraigned today on 12 counts of first-degree perjury and freed on bail.
My guess is that this sort of perjury occurs more than we realize. If there’s one place I think cameras should be rolling at all times, it’s in police station interrogation rooms. And no erasing the tapes either. (And those tapes must have been really damning. Old interrogation tapes can yield valuable intelligence; you don’t ever erase them unless you absolutely have to.)
Taking Pictures from a Train
This is a very moving story about a foreign tourist being removed from a train for taking pictures:
The train is a half hour west of New Haven when the conductor, having finished her original rounds, reappears. She moves down the aisle, looks, stops between our seats, faces the person taking pictures. “Sir, in the interest of national security, we do not allow pictures to be taken of or from this train.” He starts, “I…….” but, without English, his response trails off into silence. The conductor, speaking louder, forcefully: “Sir, I will confiscate that camera if you don’t put it away.” Again, little response. “Sir, this is a security matter! We cannot allow pictures.” She turns away abruptly and, as she moves down the aisle, calls over her shoulder, in a very loud voice, “Put. It. Away!” He packs his camera.
Within a minute after our arrival in New Haven, two armed police officers entered the car, approached my neighbor’s seat. “Sir, we’re removing you from this train.” “I….;” “I……” “Sir, you have breached security regulations. We must remove you from this train.” “I…,” “I…..” “Sir, we are not going to delay this train because of you. You will get off, or we will remove you physically.” “I…..”
Nearby passengers stir. One says, “It’s obvious he doesn’t speak English. There are people here who speak more than one language. Perhaps we can help.” Different ones ask about the traveler’s language; learn he speaks Japanese. For me, a sudden flash of memory—a student at International Christian University in Japan, I took countless pictures without arousing suspicion.
The police speak through the interpreter, with the impatience of authority. “The conductor asked this man three times to discontinue. We must remove him from the train.” The traveler hears the translation, is befuddled. Hidden beneath the commotion is a cross-cultural drama. With the appearance of police officers, this quiet visitor is embarrassed to find he is the center of attention. The officers explain, “After we remove him from the train, when we are through our investigation, we will put him on the next train.” The woman translates. The passenger replies, “I’m meeting relatives in Boston. They cannot be reached by phone. They expect me and will be worried when I do not arrive on schedule.” “Our task,” the police repeat, “is to remove you from this train. If necessary, we will do so by force. After we have finished the investigation, we’ll put you on another train.” The woman translates. The traveler gathers his belongings and departs.
My earlier suggestion that you imagine being in his place leaves you free to respond and draw your conclusions. Remember: you’ve been removed from the train, are being interrogated, perhaps having your equipment confiscated; while I continue to do what I take for granted traveling unimpeded, on to Providence.
The more I replay the scene, the more troublesome it is. It is the stuff of nightmares. Relations between people and countries lie at the heart of the issue. The abstract terms that inform political and social debate appear, as if in person, unexpectedly, near enough to hear, touch, feel. Taking no position is not an option. As an educator, I would prepare and deliver a lecture on how others perceive America in the world community, then seek an audience. I’ll spare you. But—I just watched armed police officers remove a visitor from the train for taking pictures. I don’t understand this. I’m disturbed no, shaken to bear witness to these events.
EDITED TO ADD (11/13): A response from the writer of the original article, after people questioned the veracity of the story.
Untwirling a Photoshopped Photo
So, this pedophile posts photos of himself with young boys, but obscures his face with the Photoshop “twirl” tool. Turns out that the transformation isn’t lossy, and that you can untwirl his face.
He was caught in Thailand.
Moral: Don’t blindly trust technology; you need to really know what it’s doing.
Hacking Security Cameras
If you’ve seen a Hollywood caper movie in the last 20 years you know the old video-camera-spoofing trick. That’s where the criminal mastermind taps into a surveillance camera system and substitutes his own video stream, leaving hapless security guards watching an endless loop of absolutely-nothing-happening while the bank robber empties the vault.
Now white-hat hackers have demonstrated a technique that neatly replicates that old standby.
Amir Azam and Adrian Pastor, researchers at London-based security firm ProCheckUp, discovered that they can redirect what video file is played back by an AXIS 2100 surveillance camera, a common industrial security camera that boasts a web interface, allowing guards to monitor a building from anywhere in the world.
The Technology of Homeland Security
Reuters has an article on future security technologies. I’ve already talked about automatic license-plate-capture cameras and aerial surveillance (drones and satellites), but there’s some new stuff:
Resembling the seed of a silver maple tree, the single-winged device would pack a tiny two-stage rocket thruster along with telemetry, communications, navigation, imaging sensors and a power source.
The nano air vehicle, or NAV, is designed to carry interchangeable payload modules—the size of an aspirin tablet. It could be used for chemical and biological detection or finding a “needle in a haystack,” according to Ned Allen, chief scientist at Lockheed’s fabled Skunk Works research arm.
Released in organized swarms to fly low over a disaster area, the NAV sensors could detect human body heat and signs of breathing, Allen said.
And this:
Airport screening is another area that could be transformed within 10 years, using scanning wizardry to pinpoint a suspected security threat through biometrics—based on one or more physical or behavioral traits.
“We can read fingerprints from about five meters…all 10 prints,” said Bruce Walker, vice president of homeland security for Northrop Grumman Corp (NOC.N). “We can also do an iris scan at the same distance.”
For a while I’ve been saying that this whole national ID debate will be irrelevant soon. In the future you won’t have to show ID; they’ll already know who you are.
