Face-Recognition Software Fingers Suspects

eldavojohn writes, "In Holyoke and Northampton, Massachusetts, the police have a new member on the team. It's facial recognition software that will mine the 9.5 million state license images of Massachusetts residents. From the article: 'Police Chief Anthony R. Scott said yesterday he will take advantage of the state's offer to tap into a computer system that can identify suspects through the Registry of Motor Vehicle's Facial Recognition System.' The kicker is that this system been in use since May and has been successful." An article from Iowa a few weeks back mentions that software from the same company (Digimark) is in use to catch potential fraud in applying for driver's licenses in Alabama, Colorado, Kansas, Massachusetts, Oregon, and Texas. But offering the software and photo database as a resource to police departments raises the stakes considerably. I wonder what the false positive rate is.

    The issue is more than just the false positive rate. The problem is that they are going through the entire DMV records. As it stands right now, most places can only go through previously arrested people for things like fingerprint and facial matches, which is something that comes with having a record. I, as a law abiding citizen on the other hand, should not be immediately thrown under suspicion just because my face is somewhat similar to a blurry CCTV image, which is what the false positive rate could cause. I have a job that requires me to be in a certain place at a certain time, thats not exactly possible if I am being held for questioning because of something someone I have never met did something on the other side of town. If I could trust our government to use new technologies judiciously and with restraint, it wouldn't be a problem, but this hasn't ever been the case and, short of some utopia suddenly appearing, probably never will.

    There's a fundamental, mathematical problem for any system that screens large populations looking for a small number of targets.

    Let's say your system is 99% reliable, that is to say, 1% of the time it checks a negative it reports a positive and vice versa.

    Now you screen 1,000,000 people looking for one suspect, your system turns up 10,001 positives. Which one is it?

    This is a problem that has been well-studied in cancer screenings. For certain rare types of cancers, there are nearly 100% reliable tests that nonetheless when they report a positive, are usually wrong.

    Now it's fine to say, in the case of the cancer, that the 1% of the population should be informed and then checked via another procedure or something. But when we're talking about a process that fingers potential criminals, and in modern criminal justice where merely being a suspect hurts your life in a myriad of ways (god help you if the information winds up somewhere accessible to google, or worse yet, the case has anything to do with terrorism).

    I have the same objection to large-scale wiretapping operations, if anything, the human factor there greatly increases the problem.

    This is exactly like finger printing everyone in the state. Privacy has gone out the window. Making use of photos which people allowed for use on their license, to be used to finger them is criminal.

  4. license photograph archive by JimBobJoe · · Score: 4, Insightful

    You'd be surprised how many state legislatures never bothered authorizing their respective DMVs to archive the photographs (which is a huge change from the days of the original photo licenses, where only negative was produced and no photograph maintained.)

    I just took a look at the MA code and couldn't find anything allowing the photographs to be archived by the registry of motor vehicles. Maybe someone else with a better knoweledge of MA law can find such a law.

    This is not an insignificant issue...the archival of the photographs and sharing them to law enforcement, basically without limit and without warrant to access the database, is the practical equivalent of requiring every citizen above the age of 16 to show up at the local police station and be photographed.

    I consider the photograph archival of US license pictures to be one of the biggest and least known/understood privacy invasions in the last 10-15 years.

    Well getting lies from random people on the streets would be analogous to getting a false positive from this system (except that the system arguably isn't out to frame anyone on purpose), and since police have no trouble dealing with such false positives from "tips", they should have even less trouble dealing with false positives from this system.

    I think you are assuming that the police are not having a problem
    dealing with false positives from "tips". I suspect that is not
    proven.
