Smart Cameras Detect Crime, Erode Privacy

MattSparkes writes "Smart surveillance systems could identify crimes as they take place, if a computer vision system developed at the University of Texas goes into production. The system is capable of classifying behaviour as friendly or violent. In the past there have been attempts to spot unusual behaviour, but this required subsequent user classification. These new systems may keep us more secure, but is it worth sacrificing our privacy for? And will we see false positives, where police cars screech to a halt beside hugging couples?"

  1. Just because someone pushes or punches... by garcia · · Score: 5, Insightful

    A computer vision system developed in the University of Texas in Austin, US, can already tell the difference between friendly behaviour, such as shaking hands, and aggressive actions like punching or pushing.

    Just because someone pushes or punches someone else, doesn't mean it isn't friendly. Would be flicking off a friend be considered an aggressive act?

    Let's leave this sort of shit to human judgment instead of relying on cameras all the time. We really don't need to be going down this road.

      From TFA:
      On average, the system was 80% accurate at identifying these activities correctly.

      That figure is for "staged interactions", which are likely to be more exaggerated / less ambiguous than "real life", unless they were performed by accomplished actors (meaning someone that could convincingly portray the actions to a human audience). They are also likely to have less irrelevant random "background noise".

      Just because someone pushes or punches someone else, doesn't mean it isn't friendly.

      Indeed. As it happens, I recently met a friend from college, who I haven't seen for a few years, in front of a cafe in town. He ran up and gave me a huge bear hug. I wouldn't be at all surprised if the system thought he was mugging me.

    Many people already automatically trust the machine since "it's the machine." To them, it can only fail when it's broken, not be broken by design unless it's a home electronic device. Kiss your liberties goodbye. This will make the red light cameras look like nothing.

    This is easily solvable by splitting behavior into 3 different types: Normal, dangerous, and HOT!

      Do people really have an expectation of privacy while in a public area?

      Yes. For example if you were walking around in public locations for a few hours, and I were to follow you the whole time, making notes about where you went, whom you talked to, what you bought, etc. you'ld probably feel your expectations of privacy were being violated, even though I had as much legal right of access to those locations as you did.
      Also, the original framers of the constitution aimed, in large part, to constrain government from exceeding the control of the people. Under the US system, if it is questionable at best for me, as a private citizen, to conduct public surveilance on you, then if I do it as an agent of government, it becomes even more dubious, and my requirements to show cause become greater, not less.

      So you are now proposing that the police, as government officers, should be prohibited from patrolling public areas?

      I think the police should be restricted to their real job, investigating and collecting evidence of crimes. I have no problem with them being posted in random locations, or locations with a high concentration of people to speed response times, but realistically, the police don't respond to crimes in time to prevent them, or do so very, very rarely. Quite frankly, it is not their job to watch everyone all the time just in case someone might commit a crime and it certainly is not their job to videotape everyone. In the same way it is illegal to radar gun everyone driving by, but cops break the law and abuse our rights in that regard every day, this system would be one huge infringement on our rights. If you want to live in a nanny state, please do so elsewhere. I don't need, want, or expect the police to protect me.

  5. AI-complete by Shimmer · · Score: 3, Insightful

    Without even needing to RTFA, I think we can say with high confidence that "detecting crime" is an AI-complete problem. That is, any system capable of detecting crime must also have the full intelligence of a person in order to make the complex ethical/legal judgments involved. This implies as well that the system will likely have all the accompanying quirks of personhood, including (but not limited to) a favorite baseball team and a strong desire to be on American Idol.

    Thus, we can conclude that a) the supposed system is 95% bunk, and b) anyone who eventually invents such a system for real will win the Nobel Prize and be immortalized in human history.

Every one belongs to all and all to every one. All are slaves and equal in their slavery. In extreme cases he advocates slander and murder, but the great thing about it is equality. To begin with, the level of education, science, and talents is lowered. A high level of education and science is only possible for great intellects, and they are not wanted. The great intellects have always seized the power and been despots. Great intellects cannot help being despots and they've always done more harm than good. They will be banished or put to death. Cicero will have his tongue cut out, Copernicus will have his eyes put out, Shakespeare will be stoned--that's Shigalovism. Slaves are bound to be equal. There has never been either freedom or equality without despotism, but in the herd there is bound to be equality, and that's Shigalovism! Ha ha ha! Do you think it strange?

    You don't have arrest and prosecute to squash free speech and free assembly. You just have to have persistent police investigations and police "harassment".

    ...but is it reasonable to have an expectation of privacy on the street? A tourist can snap pictures all day long and that doesn't erode privacy.

    It is not reasonable to expect that your actions in public will be kept private from other private citizens in a public area, as that would be taking away the rights of other citizens in order to provide you with privacy. The government, however, is not a private citizen and has no rights. It exists only to serve the people. In order to spend my tax dollars and intrude on the privacy of the people, they need to show a reasonable cause. Blanket surveillance under the assumption that you might be about to commit a criminal act does not meet those criteria.

    These new systems may keep us more secure, but is it worth sacrificing our privacy for?

    If government imposes these cameras on me, I will NOT refer to it as a "sacrifice" on my part, and I will NOT be told that somehow I asked for it. I NEVER gave my consent for government to spy on me. But wait, you say, if I remain on the land I was born on, then I have already volunteered my consent to any law the collective wishes to impose on me, past, present, and future!

    Wrong. The "social contract" theory claims that citizens volunteer themselves to be subject to coercion by "not leaving". This is absurd. A person cannot volunteer to be subject to coercion, any more than you can force a person to volunteer. The two modes of human interaction (voluntary association and coercion) are opposite and mutually exclusive -- that is, in fact, what gives them meaning.

    Really, I'm getting sick of hearing about how decisions made by the power elite are somehow decisions that "we" put on ourselves. A person who makes a voluntary choice doesn't NEED to be coerced.

    1) A mugging or a hugging can be over in seconds. Can the camera tell which was which before it phones the police?
    2) There'll be more cameras than patrolling cop cars. A patrolling cop car can ignore or react to an incident depending on how it unfolds. A camera that tells a cop to respond to a particular location means the cop HAS to respond.
