Nuclear Terrorism False Positives
From the AP:
A man who recently had received radiation treatment for a medical condition set off a nuclear alert detector on a fire engine, prompting police to close down a roadway in Escondido while authorities searched for a nuclear weapon.
Garbage Cans that Spy on You
From The Guardian:
Though he foresaw many ways in which Big Brother might watch us, even George Orwell never imagined that the authorities would keep a keen eye on your bin.
Residents of Croydon, south London, have been told that the microchips being inserted into their new wheely bins may well be adapted so that the council can judge whether they are producing too much rubbish.
I call this kind of thing “embedded government”: hardware and/or software technology put inside of a device to make sure that we conform to the law.
And there are security risks.
If, for example, computer hackers broke in to the system, they could see sudden reductions in waste in specific households, suggesting the owners were on holiday and the house vacant.
To me, this is just another example of those implementing policy not being the ones who bear the costs. How long would the policy last if it were made clear to those implementing it that they would be held personally liable, even if only via their departmental budgets or careers, for any losses to residents if the database did get hacked?
Security Risks of Frequent-Shopper Cards
This is from Richard M. Smith:
Tukwila, Washington firefighter, Philip Scott Lyons found out the hard way that supermarket loyalty cards come with a huge price. Lyons was arrested last August and charged with attempted arson. Police alleged at the time that Lyons tried to set fire to his own house while his wife and children were inside. According to the KOMO-TV and the Seattle Times, a major piece of evidence used against Lyons in his arrest was the record of his supermarket purchases that he made with his Safeway Club Card. Police investigators had discovered that his Club Card was used to buy fire starters of the same type used in the arson attempt.
For Lyons, the story did have a happy ending. All charges were dropped against him in January 2005 because another person stepped forward saying he set the fire and not Lyons. Lyons is now back at work after more than 5 months of being on administrative leave from his firefighter job.
The moral of this story is that even the most innocent database can be used against a person in a criminal investigation turning their lives completely upside down.
Safeway needs to be more up-front with customers about the potential downsides of shopper cards. They should also provide the details of their role in the arrest or Mr. Lyons and other criminal cases in which the company provided Club Card purchase information to police investigators.
Here is how Safeway currently describes their Club Card program in the Club Card application:
We respect your privacy. Safeway does not sell or lease personally identifying information (i.e., your name, address, telephone number, and bank and credit card account numbers) to non-affiliated companies or entities. We do record information regarding the purchases made with your Safeway Club Card to help us provide you with special offers and other information. Safeway also may use this information to provide you with personally tailored coupons, offers or other information that may be provided to Safeway by other companies. If you do not wish to receive personally tailored coupons, offers or other information, please check the box below. Must be at least 18 years of age.

Firefighter Arrested For Attempted Arson
Fireman attempted to set fire to house, charges say
T-Mobile Hack
For at least seven months last year, a hacker had access to T-Mobile’s customer network. He’s known to have accessed information belonging to 400 customers—names, Social Security numbers, voicemail messages, SMS messages, photos—and probably had the ability to access data belonging to any of T-Mobile’s 16.3 million U.S. customers. But in its fervor to report on the security of cell phones, and T-Mobile in particular, the media missed the most important point of the story: The security of much of our data is not under our control.
This is new. A dozen years ago, if someone wanted to look through your mail, they would have to break into your house. Now they can just break into your ISP. Ten years ago, your voicemail was on an answering machine in your house; now it’s on a computer owned by a telephone company. Your financial data is on Websites protected only by passwords. The list of books you browse, and the books you buy, is stored in the computers of some online bookseller. Your affinity card allows your supermarket to know what food you like. Data that used to be under your direct control is now controlled by others.
We have no choice but to trust these companies with our privacy, even though the companies have little incentive to protect that privacy. T-Mobile suffered some bad press for its lousy security, nothing more. It’ll spend some money improving its security, but it’ll be security designed to protect its reputation from bad PR, not security designed to protect the privacy of its customers.
This loss of control over our data has other effects, too. Our protections against police abuse have been severely watered down. The courts have ruled that the police can search your data without a warrant, as long as that data is held by others. The police need a warrant to read the e-mail on your computer; but they don’t need one to read it off the backup tapes at your ISP. According to the Supreme Court, that’s not a search as defined by the 4th Amendment.
This isn’t a technology problem, it’s a legal problem. The courts need to recognize that in the information age, virtual privacy and physical privacy don’t have the same boundaries. We should be able to control our own data, regardless of where it is stored. We should be able to make decisions about the security and privacy of that data, and have legal recourse should companies fail to honor those decisions. And just as the Supreme Court eventually ruled that tapping a telephone was a Fourth Amendment search, requiring a warrant—even though it occurred at the phone company switching office—the Supreme Court must recognize that reading e-mail at an ISP is no different.

Smart Water
No, really. It’s liquid with a unique identifier that is linked to a particular owner.
Forensic Coding combined with microdot technology.
SmartWater has been designed to protect household property and motor vehicles. Each bottle of SmartWater solution contains a unique forensic code, which is assigned to a household or vehicle.
An additional feature of SmartWater Instant is the inclusion tiny micro-dot particles which enable Police to quickly identify the true owner of the property.
The idea is for me to paint this stuff on my valuables as proof of ownership. I think a better idea would be for me to paint it on your valuables, and then call the police.
FBI Retires Carnivore
According to SecurityFocus:
FBI surveillance experts have put their once-controversial Carnivore Internet surveillance tool out to pasture, preferring instead to use commercial products to eavesdrop on network traffic, according to documents released Friday.
Of course, they’re not giving up on Internet surveillance. They’ve just realized that commercial tools are better, cheaper, or both.
British Pub Hours and Crime
The Economist website (only subscribers can read the article) has an article dated January 6 that illustrates nicely the interplay between security trade-offs and economic agendas.
In the 1990s, local councils were scratching around for ideas about to how to revive Britain’s inner cities. Part of the problem was that the cities were dead after their few remaining high-street shops had shut in the evening. Bringing night-life back, it was felt, would bring back young people, and the cheerful social and economic activity they would attract would revive depressed urban areas. The “24-hour city” thus became the motto of every forward-thinking local authority.
For councils to fulfil their plans, Britain’s antiquated drinking laws needed to be liberalised. That has been happening, in stages. The liberalisation culminates in 24-hour drinking licences….
This has worked: “As an urban redevelopment policy, the liberalisation has been tremendously successful. Cities which once relied on a few desultory pubs for entertainment now have centres thumping with activity from early evening all through the night.”
On the other hand, the change comes with a cost. “That is probably why, when crime as a whole has fallen since the late 1990s, violent crime has gone up; and it is certainly why the police have joined the doctors in opposing the 24-hour licences.”
This is all perfectly reasonable. All security is a trade-off, and a community should be able to trade off the economic benefits of a revitalized urban center with the economic costs of an increased police force. Maybe they can issue 24-hour licenses to only a few pubs. Or maybe they can issue 22-hour licenses, or licenses for some other number of hours. Certainly there is a solution that balances the two issues.
But the organization that has to pay the security costs for the program (the police) is not the same as the organization that reaps the benefits (the local governments).
Over the past hundred years, central government’s thirst for power has weakened the local authorities. As a result, policing, which should be a local issue, is largely paid for by central government. So councils, who are largely responsible for licensing, do not pay for the negative consequences of liberalisation.
The result is that the local councils don’t care about the police costs, and consequently make bad security trade-offs.
Terrorists and Border ID Systems
This Washington Times article titled “Border Patrol hails new ID system” could have just as accurately been titled “No terrorists caught by new ID system.”
Border Patrol agents assigned to U.S. Customs and Border Protection (CBP) identified and arrested 23,502 persons with criminal records nationwide through a new biometric integrated fingerprint system during a three-month period beginning in September, CBP officials said yesterday.
Terrorism justifies the security expense, and it ends up being used for something else.
During the three-month period this year, the agents identified and detained 84 homicide suspects, 37 kidnapping suspects, 151 sexual assault suspects, 212 robbery suspects, 1,238 suspects for assaults of other types, and 2,630 suspects implicated in dangerous narcotics-related charges.
Behavioral Assessment Profiling
On Dec. 14, 1999, Ahmed Ressam tried to enter the United States from Canada at Port Angeles, Wash. He had a suitcase bomb in the trunk of his car. A US customs agent, Diana Dean, questioned him at the border. He was fidgeting, sweaty, and jittery. He avoided eye contact. In Dean’s own words, he was acting “hinky.” Ressam’s car was eventually searched, and he was arrested.
It wasn’t any one thing that tipped Dean off; it was everything encompassed in the slang term “hinky.” But it worked. The reason there wasn’t a bombing at Los Angeles International Airport around Christmas 1999 was because a trained, knowledgeable security person was paying attention.
This is “behavioral assessment” profiling. It’s what customs agents do at borders all the time. It’s what the Israeli police do to protect their airport and airplanes. And it’s a new pilot program in the United States at Boston’s Logan Airport. Behavioral profiling is dangerous because it’s easy to abuse, but it’s also the best thing we can do to improve the security of our air passenger system.
Behavioral profiling is not the same as computerized passenger profiling. The latter has been in place for years. It’s a secret system, and it’s a mess. Sometimes airlines decided who would undergo secondary screening, and they would choose people based on ticket purchase, frequent-flyer status, and similarity to names on government watch lists. CAPPS-2 was to follow, evaluating people based on government and commercial databases and assigning a “risk” score. This system was scrapped after public outcry, but another profiling system called Secure Flight will debut next year. Again, details are secret.
The problem with computerized passenger profiling is that it simply doesn’t work. Terrorists don’t fit a profile and cannot be plucked out of crowds by computers. Terrorists are European, Asian, African, Hispanic, and Middle Eastern, male and female, young and old. Richard Reid, the shoe bomber, was British with a Jamaican father. Jose Padilla, arrested in Chicago in 2002 as a “dirty bomb” suspect, was a Hispanic-American. Timothy McVeigh was a white American. So was the Unabomber, who once taught mathematics at the University of California, Berkeley. The Chechens who blew up two Russian planes last August were female. Recent reports indicate that Al Qaeda is recruiting Europeans for further attacks on the United States.
Terrorists can buy plane tickets—either one way or round trip—with cash or credit cards. Mohamed Atta, the leader of the 9/11 plot, had a frequent-flyer gold card. They are a surprisingly diverse group of people, and any computer profiling system will just make it easier for those who don’t meet the profile.
Behavioral assessment profiling is different. It cuts through all of those superficial profiling characteristics and centers on the person. State police are trained as screeners in order to look for suspicious conduct such as furtiveness or undue anxiety. Already at Logan Airport, the program has caught 20 people who were either in the country illegally or had outstanding warrants of one kind or another.
Earlier this month the ACLU of Massachusetts filed a lawsuit challenging the constitutionality of behavioral assessment profiling. The lawsuit is unlikely to succeed; the principle of “implied consent” that has been used to uphold the legality of passenger and baggage screening will almost certainly be applied in this case as well.
But the ACLU has it wrong. Behavioral assessment profiling isn’t the problem. Abuse of behavioral profiling is the problem, and the ACLU has correctly identified where it can go wrong. If policemen fall back on naive profiling by race, ethnicity, age, gender—characteristics not relevant to security—they’re little better than a computer. Instead of “driving while black,” the police will face accusations of harassing people for the infraction of “flying while Arab.” Their actions will increase racial tensions and make them less likely to notice the real threats. And we’ll all be less safe as a result.
Behavioral assessment profiling isn’t a “silver bullet.” It needs to be part of a layered security system, one that includes passenger baggage screening, airport employee screening, and random security checks. It’s best implemented not by police but by specially trained federal officers. These officers could be deployed at airports, sports stadiums, political conventions—anywhere terrorism is a risk because the target is attractive. Done properly, this is the best thing to happen to air passenger security since reinforcing the cockpit door.
