Sony Promises Better Face Identification Through Depth-Sensing Lasers (theverge.com) 46

An anonymous reader quotes a report from The Verge: Speaking with Bloomberg last week, Sony's sensor division boss Satoshi Yoshihara said Sony plans to ramp up production of chips to power front and rear 3D cameras in late summer, responding to demand from multiple smartphone manufacturers. Though Yoshihara is geeked about the potential for augmented reality applications, the most intriguing aspect of this new tech would appear to be a better form of face identification than we currently have. The Face ID approach that Apple first brought into use on the iPhone X -- and others like Xiaomi, Huawei, and Vivo have since emulated -- works by projecting out a grid of invisible dots and detecting the user's face by the deformations of that grid in 3D space. Sony's 3D sensor, on the hand, is said to deploy laser pulses, which, much like a bat's echolocation, creates a depth map of its surroundings by measuring how long a pulse takes to bounce back. Sony's sensor chief argues this produces more detailed models of users' faces, plus it apparently works from as far away as five meters (16 feet).

      Also best not to allow the phone to sense light and construct a 2D image that a good computer program could convert into 3D provided enough light from different angles. I hear electric tape is pretty good for preventing light from coming or going out, tin foil works pretty well too and has other benefits to blocking incoming EM signals that can be used to determine the location or send out sound picked up by said phone.

      The most risky thing I tend to do every day is my daily commute. Over the past 10 years with this particular commute, I have gotten into one accident which no one was hurt except for my car and my bank wallet. (a Prius will take more damage then a Hummer does on impact)

        Let me tell you all about this scary as hell common chemical called DHMO. Deadly in every form it is, and completely unregulated, they put in everything from medicine to toilet cleaner!

      • Besides, you only have to worry about unlicensed Sony IP on your device. If it detects any (or thinks it does), it will ramp up the laser power until your face is burnt to a crisp. Easy fix: Take a sharpie and mark over the outside rim of the laser lens.

      How? These aren't fucking laser guns, not even laser pointers. Exactly what danger do you think they pose?

        You say this now, but what happens when some evil hacker turns one of these up to say 5MW?

        Actually that would be kind of cool if it was possible.

    • To map face conttours one is going to need sub-centimeter resolution. I'd speculate that to actually make this distinguishing -- the point of face recognition, one would need millimeter resolution. SO that would put the time reolution below 30 picoseconds.

    • Man, you can tell the slashdot crowd is aging. Next people will be complaining that robots are going to break in an take their medication.

      Anyone that is going to hack your phone to get the layout of your house will have the capability to know if you are there or not. If they intend you harm, it would be easier just to catch you as you leave or enter.

      You are being a chicken little.

    I imagine the caution label on this will be something like...

  • All the comments so far are some variation on "oh no, shooting LAZORS at someone!"

    I've worked with both the pattern projection systems (like kinect) and the TOF imaging chips. The TOF systems are a more elegant solution, but don't seem to be all that superior in practice. Since they use interference they have a window of distances they're sensitive to, with a tradeoff of precision and how deep the window is.

  • FaceID is vastly better than fingerprint detection so I am happy to see Sony offering something to where this can be offered to many other phone makers...

    It's only half of the equation though, once you get a detailed depth map you need software to be able to verify it's an authenticated face. Probably Sony will have some kind of reference implementation for that, that while not as good as Apple's will be good enough for most people.

      Purely curious, but what about FaceID do you find to be vastly superior? Many people I have spoken to seem to be somewhat indifferent about it (in comparison to TouchID) and usually I am told about how each has its pros and cons. I'm still using a phone with a thumbprint reader and I am content with it; never felt like it was so inconvenient that I needed facial recognition.

      • by jimbo ( 1370 )

        Yeah GP was a bit too hyperbolic and I've been happy with either method. It's not that TouchId is "so inconvenient that I needed facial recognition" - that's hyperbole too.
        So TouchId was never anywhere near inconvenient, it's great but for me FaceId *is* an improvement and it's even more seamless an fails even less often.

        That's me though; for some it's the other way around and others need to disable "attention detection" for it to work well.

        Because I don't have to ever think consciously about authenticating, it just happens. As someone else said in the past, the feel of it is like using a phone without a passcode... A few examples:

        1) Notifications show up, but text is not revealed until I look at the phone.

        2) I really can just Siri to open any app with the phone locked, and it will open up without having to wait for the prompt to unlock.

  • "Do not look at the laser light with your remaining eye."

    Maybe it's just me but I still wonder about why anyone is putting so much valuable information on their phone that it needs this level of security. If I lose my phone or it's stolen, all the finder/thief is going to get is my contacts' phone numbers, some photos, and music I've copied onto the phone. No need to have laser facial scanning to protect that. (Nope... no online banking and definitely no social networking via my phone.)
