Google Images + Facial Recognition Find Thief Who Looked Like Woody Harrelson (nbcnewyork.com) 53

"The New York Police Department used a photo of Woody Harrelson in its facial recognition program in an attempt to identify a beer thief who looked like the actor," reports the Associated Press: Georgetown University's Center on Privacy and Technology highlighted the April 2017 episode in "Garbage In, Garbage Out," a report on what it says are flawed practices in law enforcement's use of facial recognition. The report says security footage of the thief was too pixelated and produced no matches while high-quality images of Harrelson, a three-time Oscar nominee, returned several possible matches and led to one arrest.

The NYPD also used a photo of a New York Knicks player to search its database for a man wanted for a Brooklyn assault, the report said.

"The stakes are too high in criminal investigations to rely on unreliable â" or wrong â" inputs," Georgetown researcher Clare Garvie wrote.... The Georgetown report says facial recognition has helped the NYPD crack about 2,900 cases in more than five years of using the technology.

And in Florida, Vice reports, law enforcement agencies "run roughly 8,000 of these searches per month."

    The algorithm flagged Woody Harrleson's father as a criminal.

      I wonder if anyone here will understand your reference.

      For those who don't know, Woody Harrelson's father, Charles Harrelson, was a convicted murderer of a Judge. He was also tried, but never convicted, for multiple murders prior to that. And briefly he was connected to the JFK assassination.

    If you want to find something that matches something else there's two ways you can do this. One way is to invent the "one-true-distance-metric" for what exactly you mean by "matching" for two different photos. Another way is to take a set of example photos that you think all resemble the thing of interest, then pull up all the images that match all of these (not just one of them).

    The latter is effectively the same notion behind a support vector machine. You rely on the distance metric or kernel for short range comparisons but you choose new comparison points as you take larger steps in the feature space.

    Everyone knows the support vector concept is vastly better than trying to claim these is any one true distance metric. You just can't transfer what you know to the math. But you can learn from trnasferable examples.

    Using just a single "woody harrelson" is kind of an extreme case of using just one support vector. It would be better to take all the mug book matches from witnesses then automate finding faces similar to all of those.

      In much of the world criminal justices systems are set up with absurd penalties and insurmountable odds for defendants. As such conviction rates are insanely high because a prosecutor will make you either take a plea bargain or risk a trial putting you in jail for 20 years for stealing beer (three strikes laws [wikipedia.org]).

      That's why there can be no ambiguity in the process. Once it starts you'll have the cops catching the wrong perp and prosecutors throwing them in prison for months on end because they can't risk a jury just not liking the look of them.

      True story, I've been on 1 jury in my life and I had a woman say to me with a straight face "We can't allow our feelings to get in the way of our decision and we must get this guy off the streets". Everyone I know has at least 1 story like that. If you're up for a crime you wanna gamble on that?

        We don't need facial recognition to catch the wrong person and force a plea bargain. That has been happening for decades while facial recognition is new.

        So our fear of giving the police new tools is based on a problem that has no relationship to those tools. We should start looking at solving the problem.

        All tools require responsible users. We do not trust our officers to be responsible users at the moment, and there are a lot of good reasons behind that.

        Personally, I believe we need to get off the crime prevention kick and roll things back to the days when police were well-trained, well-paid, predominantly college-educated professional investigators pursuing those who had already committed real crimes.

        These matches are not evidence for arrest. They are cause to go have a conversation with a person. Just like one person saying so and so and resembles that photo. The computer match is nothing more, so and so resembles that photo, it is not eye witness testimony which is more of the nature "I personally witnessed that person do such and such". Two very different things. Only the witness testimony is evidence, not any claims of resemblance.

        • Probable cause. With our Drug War there is almost always a reason to arrest someone. 25% of people smoke pot. That means odds are good you know somebody who does. My guitarist bud once lost a ton of equipment to civil asset forfeiture because the drummer in his garage band was dealing weed. He got off lucky. They were kids, and the drummer's parents had their home seized. Not sure if they ever got it back.

    This kind of stuff is what make facial recognition really scary: many people look similar. The problem is less with the technology and more with the fact that you can rapidly find yourself in a situation where you have to prove your innocence. The job of the police is not to find who committed a crime, it's to close cases and that can mean arresting a close enough match and passing it to a prosecutor. The prosecutor's job isn't to make sure they are prosecuting the right people or ensure a fair trial, it's to scare people into taking pleabargains and getting convictions.

    Far too many people in the legal system are use the out, "I'm just doing my job," and are all too eager to send people to prison because ensuring there is justice is time consuming and therefore costly to the state.

      You are completely misunderstanding what happened. The police did NOT stick a picture of Woody Harrelson into a computer, then immediately go arrest the people that cam up as likely matches.

      Instead, the criminal was described as looking like Harrelson. However, the police did not have a good image from the security cameras. However, using a picture of Harrelson (this the criminal was described as looking like him) allowed them to ID several people that had similar faces.

      The police then investigated those

      No it is not a matter of proving your innocence. Whether a person or a computer says you resemble the person in the photo the situation is the same, that it is cause for a conversation not evidence against you. Its not like a witness who claims to have directly seen you do something. Its just noting a resemblance. It only gives police people to go have a talk with, to investigate to some degree. That is what the police do, investigate. And being told you resemble someone in a photo is cause for investigatio

        Well no, this is far worse, this is in fact the legal equivalent of swatting. What if they use your image as a nobody and a couple of trigger happy law enforcers empty their magazines into your chest because they were scared of your phone, their defence, that was your photo and you were accused of being armed and dangerous and they felt unsafe. The law enforcers involved should be prosecuted, they have absolutely zero right to place an innocent member of the public at risk and they very much did so. This is

  • Facial recognition matches the wrong faces. Humans mismatch people more than half the time when trying to match pictures to someone they only saw once. Blood or DNA could be there for other reasons. A fingerprint could be yours and there for reasons other than involvement in a crime. Video is vulnerable to misinterpretation - for example a video of someone trying to save a drowning person would almost always look like they are drowning them because drowning people fight. Etc. etc.

    and they later arrested him for petty larceny — adding to the mounting evidence that police are using facial recognition

    This is a very dangerous development.

    Suppose you spend a night reading a book at home on the couch. A few weeks later, the police barge in and charge you with a murder that happened that night. If you have a partner/roommate that will vouch for you being on the couch all night, they don't believe him/her: you guys are partners, they would always backup your alibi even if you were away. Now you're in real trouble.

    This could of course always happen, but if they show up, they normally have substantial hints t
