Google Patents Frowns and Winks To Unlock Your Phone 89

Excelcia writes "Users could soon be asked to pull a series of faces to unlock their Android phones or tablets. Google has filed a patent suggesting users stick out their tongue or wrinkle their nose in place of a password. Requiring specific gestures could prevent the existing Face Unlock facility being fooled by photos. The software could monitor if there were changes in the angle of the person's face to ensure the device was not being shown a still image with a fake gesture animated on top."

        The easy way to film someone's unlock gesture would be swap their phone with one that looks just like theirs, and have the decoy phone record them when they do the unlock gesture to unlock it. The decoy phone can prompt the user with several fake authentication attempts to get them to cycle through several different expressions and build up a library of the appropriate expressions to play back. A 3D camera on the phone would make this much harder (but not impossible since you could record in 3D and rig so

            There's already an option to require a blink during authentication so that photo's won't work. Your wife should probably enable that.

            That sounds only moderately more secure, so instead of a static picture of her, I'd just need a video of her blinking, perhaps with my finger poised on the "play" button so I can make it blink when the phone asks for it.

            Plus, I think her phone is still on ICS, so she doesn't have the liveness check option.

            • Face unlock and slide to unlock are only intended to be moderately secure anyway. It's a trade off, because strong security is inconvenient. That said, photos of people's faces are generally much easier to come by than videos of people staring straight into a camera and blinking.

          That's ok though because they can scan all the video and tell the lock screen not to work if it matches.

      The real story here is that Google's face recognition has got good enough to recognize expressions. Actually they revealed that it goes a fair way beyond that at their I/O conference. Picasa will now photoshop an image where everyone is smiling by combining faces from several similar images in your albums, for example.

      This is just one trivial and stupid application that the media likes to latch on to, rather than explain the real innovation. Presumably they think their readers are morons or something.

      The existing face unlock handles those fine as long as you do additional captures. And if all else fails, there's the pattern/pin/password backup lock it requires you to have.

          Which I won't have committed to memory since I haven't used it since purchasing the phone 11 months ago and setting up facial recognition.

          My phone lets me make an emergency call without unlocking it. I believe there are some apps that allow additional numbers (i.e. Mountain Rescue, your wife, etc) to be set as emergency contacts that can be dialed without unlocking.

          • "My phone lets me make an emergency call without unlocking it. I believe there are some apps that allow additional numbers (i.e. Mountain Rescue, your wife, etc) to be set as emergency contacts that can be dialed without unlocking."

            Why not let people dial any number in contacts?
            If somebody steals my phone, he can gladly talk to Aunt Nasty as much as he likes, as long as it prevents him from calling anybody _he_ knows.

            He could even call my ICE contact to tell him he's found my phone.

        • Which I won't have committed to memory since I haven't used it since purchasing the phone 11 months ago and setting up facial recognition.

          On the upside, presumably facial recognition phones will have a tough time in the dark and other rare scenarios like darkness that it will fail often enough that I'll need to use the pin code often enough to keep it in memory. But then, if it fails half the time ... why bother using it at all. Any time or convenience gained by using it when it works is lost by trying it when it doesn't work. And lets be honest here... making faces at your phone to unlock it is rarely going to be more "convenient" anyway.

          1. It requires you to enter the pattern/pin/password any time you to an additional capture.

          2. Yes, it does fail in darkness, usually because the camera can't pick up anything at all, much less a face. Also fails if you have your back to the sun or such.

          3. I'd say it works about 90% of the time in my experience.

        I used face unlock for a short, short period on one laptop once.
        why didn't I bother with it? it was faster to open it by typing in the password.. not really because it was a bad recognizer.. it worked pretty well, but just waiting for the webcam to adjust to lighting is two seconds too much.

        the zigzag gestures are faster than using face recognition on a phone..

    Imagine it.

  • In many discussions about the problem of facial recognition being used to unlock something, and the weakness to a photo, I have never seen anyone comment about using odd faces or expressions as the unlock. Remember that 'obvious in retrospect' doesn't mean unpatentable. This process is unique and non-obvious in my opinion, as well as being a good idea. It shouldn't be patentable (because software patents = math = unpatentable), but it is at least a good idea.
