British High Schoolers Write About CCTV in School

If you think that under-20-year-olds don’t care about privacy, this is an eloquent op-ed by two students about why CCTV cameras have no place in their UK school:

Adults are often quick to define the youth of today as stereotypical troublemakers and violent offenders—­ generalisations which are prompted by the media—­ when in fact the majority of students at our school are as responsible and arguably better behaved then the majority of adults. Some commentators insinuated that we overheard adults talking about rights and repeated it. That notion isn’t worth the space it was typed upon. We are A-level politics students who have been studying civil liberties as part of the curriculum for the last two years. Sam campaigned for David Davis when he resigned over the issue of civil liberties and spoke at speakers’ corner about the issue. The criticism of our campaign only serves to illustrate the ignorance of adults who have surrendered within only the last few years our right to protest in parliament, our right to go about our business without being stopped and questioned by police about our identity and our affairs, and our personal privacy.

Eroding standards in schools and deteriorating discipline are down to a broken society and the failure of the education system. The truth is that we are whatever the generation before us has created. If you criticise us, we are your failures; and if you applaud us we are your successes, and we reflect the imperfections of society and of human life. If you want to reform the education system, if you want to raise education standards, then watching children every hour of every day isn’t the answer. The answer is to encourage students to learn by creating an environment in which they can express their ideas freely and without intimidation.

Using Surveillance Cameras to Detect Cashier Cheating

It’s called “sweethearting”: when cashiers pass free merchandise to friends. And some stores are using security cameras to detect it:

Mathematical algorithms embedded in the stores’ new security system pick out sweethearting on their own. There’s no need for a security guard watching banks of video monitors or reviewing hours of grainy footage. When the system thinks it’s spotted evidence, it alerts management on a computer screen and offers up the footage.

[…]

Big Y’s security system comes from a Cambridge, Mass.-based company called StopLift Inc. The technology works by scouring video pixels for various gestures and deciding whether they add up to a normal transaction at the register or not.

How good is it? My guess is that it’s not very good, but this is an instance where that may be good enough. As long as there aren’t a lot of false positives—as long as a person can quickly review the suspect footage and dismiss it as a false positive—the cost savings might be worth the expense.

The Terrorism Arrests that Weren't

Remember those terrorism arrests that the UK government conducted, after a secret document was accidentally photographed? No one was charged:

The Crown Prosecution Service said there was insufficient evidence to press charges or hold them any longer.

The Muslim Council of Britain said the government behaved “very dishonourably” over the treatment of the men should admit it had made a mistake.

Of the 12 men arrested in the raids, 11 were Pakistani nationals, 10 held student visas and one was from Britain.

How Not to Carry Around Secret Documents

Here’s a tip: when walking around in public with secret government documents, put them in an envelope.

A huge MI5 and police counterterrorist operation against al-Qaeda suspects had to be brought forward at short notice last night after Scotland Yard’s counter-terrorism chief accidentally revealed a briefing document.

[…]

The operation was nearly blown when Assistant Commissioner Bob Quick walked up Downing Street holding a document marked “secret” with highly sensitive operational details visible to photographers.

The document, carried under his arm, revealed how many terrorist suspects were to be arrested, in which cities across the North West. It revealed that armed members of the Greater Manchester Police would force entry into a number of homes. The operation’s secret code headed the list of action that was to take place.

Now the debate begins about whether he was just stupid, or very very stupid:

Opposition MPs criticised Mr Quick, with the Liberal Democrats describing him as “accident prone” and the Conservatives condemning his “very alarming” lapse of judgement.

But former Labour Mayor of London Ken Livingstone said it would be wrong for such an experienced officer to resign “for holding a piece of paper the wrong way”.

It wasn’t just a piece of paper. It was a secret piece of paper. (Here’s the best blow-up of the picture. And surely these people have procedures for transporting classified material. That’s what the mistake was: not following proper procedure.

He resigned.

Thefts at the Museum of Bad Art

I’m not making this up:

The loss of two MOBA works to theft has drawn media attention, and enhanced the museum’s stature. In 1996, the painting Eileen, by R. Angelo Le, vanished from MOBA. Eileen was acquired from the trash by Wilson, and features a rip in the canvas where someone slashed it with a knife even before the museum acquired it, “adding an additional element of drama to an already powerful work,” according to MOBA.

The museum offered a reward of $6.50 for the return of Eileen, and although MOBA donors later increased that reward to $36.73, the work remained unrecovered for many years. The Boston Police listed the crime as “larceny, other,” and Sacco was reported saying she was unable to establish a link between the disappearance of Eileen and a notorious heist at Boston’s famed Isabella Stewart Gardner Museum that occurred in 1990. In 2006—10 years after Eileen was stolen—MOBA was contacted by the purported thief demanding a $5,000 ransom for the painting; no ransom was paid, but it was returned anyway.

Prompted by the theft of Eileen, MOBA staff installed a fake video camera over a sign at their Dedham branch reading: “Warning. This gallery is protected by fake video cameras.” Despite this deterrent, in 2004 Rebecca Harris’ Self Portrait as a Drainpipe was removed from the wall and replaced with a ransom note demanding $10, although the thief neglected to include any contact information. Soon after its disappearance the painting was returned, with a $10 donation. Curator Michael Frank speculates that the thief had difficulty fencing the portrait because “reputable institutions refuse to negotiate with criminals.”

Be sure and notice the camera.

Privacy in the Age of Persistence

Note: This isn’t the first time I have written about this topic, and it surely won’t be the last. I think I did a particularly good job summarizing the issues this time, which is why I am reprinting it.

Welcome to the future, where everything about you is saved. A future where your actions are recorded, your movements are tracked, and your conversations are no longer ephemeral. A future brought to you not by some 1984-like dystopia, but by the natural tendencies of computers to produce data.

Data is the pollution of the information age. It’s a natural byproduct of every computer-mediated interaction. It stays around forever, unless it’s disposed of. It is valuable when reused, but it must be done carefully. Otherwise, its after effects are toxic.

And just as 100 years ago people ignored pollution in our rush to build the Industrial Age, today we’re ignoring data in our rush to build the Information Age.

Increasingly, you leave a trail of digital footprints throughout your day. Once you walked into a bookstore and bought a book with cash. Now you visit Amazon, and all of your browsing and purchases are recorded. You used to buy a train ticket with coins; now your electronic fare card is tied to your bank account. Your store affinity cards give you discounts; merchants use the data on them to reveal detailed purchasing patterns.

Data about you is collected when you make a phone call, send an e-mail message, use a credit card, or visit a website. A national ID card will only exacerbate this.

More computerized systems are watching you. Cameras are ubiquitous in some cities, and eventually face recognition technology will be able to identify individuals. Automatic license plate scanners track vehicles in parking lots and cities. Color printers, digital cameras, and some photocopy machines have embedded identification codes. Aerial surveillance is used by cities to find building permit violators and by marketers to learn about home and garden size.

As RFID chips become more common, they’ll be tracked, too. Already you can be followed by your cell phone, even if you never make a call. This is wholesale surveillance; not “follow that car,” but “follow every car.”

Computers are mediating conversation as well. Face-to-face conversations are ephemeral. Years ago, telephone companies might have known who you called and how long you talked, but not what you said. Today you chat in e-mail, by text message, and on social networking sites. You blog and you Twitter. These conversations – with family, friends, and colleagues – can be recorded and stored.

It used to be too expensive to save this data, but computer memory is now cheaper. Computer processing power is cheaper, too; more data is cross-indexed and correlated, and then used for secondary purposes. What was once ephemeral is now permanent.

Who collects and uses this data depends on local laws. In the US, corporations collect, then buy and sell, much of this information for marketing purposes. In Europe, governments collect more of it than corporations. On both continents, law enforcement wants access to as much of it as possible for both investigation and data mining.

Regardless of country, more organizations are collecting, storing, and sharing more of it.

More is coming. Keyboard logging programs and devices can already record everything you type; recording everything you say on your cell phone is only a few years away.

A “life recorder” you can clip to your lapel that’ll record everything you see and hear isn’t far behind. It’ll be sold as a security device, so that no one can attack you without being recorded. When that happens, will not wearing a life recorder be used as evidence that someone is up to no good, just as prosecutors today use the fact that someone left his cell phone at home as evidence that he didn’t want to be tracked?

You’re living in a unique time in history: the technology is here, but it’s not yet seamless. Identification checks are common, but you still have to show your ID. Soon it’ll happen automatically, either by remotely querying a chip in your wallets or by recognizing your face on camera.

And all those cameras, now visible, will shrink to the point where you won’t even see them. Ephemeral conversation will all but disappear, and you’ll think it normal. Already your children live much more of their lives in public than you do. Your future has no privacy, not because of some police-state governmental tendencies or corporate malfeasance, but because computers naturally produce data.

Cardinal Richelieu famously said: “If one would give me six lines written by the hand of the most honest man, I would find something in them to have him hanged.” When all your words and actions can be saved for later examination, different rules have to apply.

Society works precisely because conversation is ephemeral; because people forget, and because people don’t have to justify every word they utter.

Conversation is not the same thing as correspondence. Words uttered in haste over morning coffee, whether spoken in a coffee shop or thumbed on a BlackBerry, are not official correspondence. A data pattern indicating “terrorist tendencies” is no substitute for a real investigation. Being constantly scrutinized undermines our social norms; furthermore, it’s creepy. Privacy isn’t just about having something to hide; it’s a basic right that has enormous value to democracy, liberty, and our humanity.

We’re not going to stop the march of technology, just as we cannot un-invent the automobile or the coal furnace. We spent the industrial age relying on fossil fuels that polluted our air and transformed our climate. Now we are working to address the consequences. (While still using said fossil fuels, of course.) This time around, maybe we can be a little more proactive.

Just as we look back at the beginning of the previous century and shake our heads at how people could ignore the pollution they caused, future generations will look back at us – living in the early decades of the information age – and judge our solutions to the proliferation of data.

We must, all of us together, start discussing this major societal change and what it means. And we must work out a way to create a future that our grandchildren will be proud of.

Billboards that Watch you Back

Creepy:

Small cameras can now be embedded in the screen or hidden around it, tracking who looks at the screen and for how long. The makers of the tracking systems say the software can determine the viewer’s gender, approximate age range and, in some cases, ethnicity—and can change the ads accordingly.

That could mean razor ads for men, cosmetics ads for women and video-game ads for teens.

And even if the ads don’t shift based on which people are watching, the technology’s ability to determine the viewers’ demographics is golden for advertisers who want to know how effectively they’re reaching their target audience.

While the technology remains in limited use for now, advertising industry analysts say it is finally beginning to live up to its promise. The manufacturers say their systems can accurately determine gender 85 to 90 percent of the time, while accuracy for the other measures continues to be refined.

These are ads at eye level: on the streets, in malls, in train stations.

Man Arrested by Amtrak Police for Taking Photographs for Amtrak Photography Contest

You can’t make this stuff up. Even Stephen Colbert made fun of it.

This isn’t the first time Amtrak police have been idiots.

And in related news, in the U.K. it soon might be illegal to photograph the police.

EDITED TO ADD (2/10): The photographer’s page about the incident has been replaced with the words “No comment!” Anyone have a link to a copy? In the meantime, here’s an entry about the incident on a photo activist’s blog.

EDITED AGAIN: Thanks to Phil M. in comments for finding these Google Cache links from Duane Kerzic’s site:

Phil adds: “The main Amtrak page on his site has since been crawled, so Google now has the ‘no comment’ note cached.”
