Lenovo Trying Face Recognition For Logins On New Laptops 164

Posted by Soulskill
from the careful-about-shaving-that-beard dept.
judgecorp writes "Lenovo's new IdeaPads will be using face recognition as a way to replace passwords for users logging onto the laptops. 'Lenovo's VeriFace combines the Windows login and file encryption to password-protect individual files. It identifies users by matching unique features of their faces to photographs taken by the 1.3-megapixel webcam built into the laptop. When Windows users start up their PCs, a camera window pops up in the login frame. The user then just has to adjust their position so their face appears in the window, and VeriFace logs them in automatically.' That could be good, but is the technology really ready for mass market devices? HP ran into trouble when its face recognition software had trouble recognizing people with darker skin."

      I have one of the new IdealPads with face recognition. The computers are gorgeous and face recognition works well. The first thing I tried was to print a photography of mine with good quality on a 4 arc of paper to see if i could fool the program to think that it was the real me. It didn't work, so I think it's ***reasonably*** secure.

        I didn't even try that, although its an obvious test.

        Lenovo's face recognition failed for me because it slows down the login process. Even where it worked right off the bat (which it didn't always) it has to load the software, take the picture, scan it, then analyze it. If your face isn't optimally positioned, you have to stop what you're doing and orient yourself correctly to give the software a chance.

        The result was far *slower* than typing a password in, so what was the point? If it were as instantaneous, flexible and reliable as human face recognition, that would be a different matter.

      Well, as always when it comes to security: whether the method is suitable depends on the attack scenario you want to protect yourself against. Neither a password nor face recognition provides significant protection against someone with a screw driver who manages to get physical access to the machine. If you want to protect the data on the disk, you need to encrypt the data and use a strong password.

        The facial recognition has been circumvented on these with a photo of moderate quality. Since the camera doing the recognition is a 1.3mp camera, the absolute most you'll need to beat it is a 2mp photo, and likely a lot less than that will work. A new/clean driver's license photos might work, but a worn one probably wouldn't.

        The only way I see them preventing a simple photograph from circumventing this is using two cameras, scanning at different angles, and making sure the two images are slightly different but still match. In that case you would need a fairly complicated rig to get the cameras to look at two photos at once in order to fool them. Much better, but not exactly secure.

        As it is now, these are even less secure than fingerprint readers, which can be beaten with a lifted fingerprint (laptop readers require a transparency, but doors can be done with black dust and tape).

        The reality is biometrics never work like the movies. An image of your face can be recorded in high enough quality to fool a scanner, your voice can be recorded in high enough quality to fool a scanner, a good camera (around $1k or so) can even get a high quality copy of your retina from a long enough distance that you'd never know it happened, which could then fool a scanner. Fingerprints have always been a joke to bypass. In many cases you can lift the necessary print right off the scanner - you might as well have a sticky note on the screen with your password on it.

        All of them are easier to bypass than a simple non-dictionary password. A pass-phrase is several orders of magnitude more secure than the lot, and the easiest to remember. It's only when you want to make passwords super secure that people start writing them on stickies and slapping them on their monitors (note that I have actually experienced this in secure government facilities - it's extremely common when very complex passwords are required). You might as well just use biometrics then, for all the good it is doing you.

    To make face recognition more secure, perhaps they should use two camera's and get a 3d scan of the face (can be fooled as well but less easy), or require that the face is moving. Perhaps even ask the user to read a randomly chosen word and lip-read the response.

      Finger print readers are about the easiest of the biometrics to crack. The press-and-hold type of scanners you can usually just use fingerprint dust and clear tape to fool them, and you can get a good print right off the scanner. For the slide-type readers, you have to lift the finger print then make a transparency to break in. Not exactly difficult.

      Seriously, Mythbusters did an episode on it, and it was shockingly easy to break into a fingerprint locked computer or door.

      Stick with a password if you care anything at all about your data. If you don't want anybody to get your data ever, encrypt and lock your machine with a passphrase. If you just want to nominally lock the machine (like setting the little chain lock on an apartment door or using WEP for your wireless router), then biometrics are fine.

    Neat things: You can make movement a requirement for login (like you have to shift your head, open your mouth, etc) in order to bypass people using your picture to login. As for fals

      The one my Dad got a year and a half ago had it, I remember because it was the first thing I had to disable for him.

    The technology is pretty nifty. At work, where we bring in many customer laptops to do virus cleanings etc., one computer had a very long and annoying password. After logging in once, then needing to reboot, I went to log in again, and the login box flashed away just as I put my hands to the keyboard. I logged back out to check, and I found that it had taken a sample image of my face on my first login without my noticing (it did say it was doing it; I just wasn't paying attention), and on the second login i

    To those bellyaching about "security", It's targeted at the consumer... not the pinnacle of perfection demanding hyper geek crowd who demands absolute security. You can always disable the face recognition in favor of windoze login. If you are a cyber crook like gifted facial contortionist like Jim Carrey aimed at thieving a user's data great. You know who you are! As far as it having trouble recognizing those with darker complexion, perhaps the low resolution camera combined with poor lighting could be a factor. My laptop doesn't always recognize me in low light, and I just have a nice George Hamilton tan :)
  • Passwords have a number of things that biological features don't have.

    1) They are a secret
    2) They can be changed at will
    3) They don't require a physical feature (you can keep them in your mind).

    Biological features are thought to be great because of their uniqueness. But the problem is that once they are compromised, it is permanent. So they are never good by themselves.

    1- The best security is something you know + something you have, so password + face sounds good.

    2- Oftentimes, when you use only one of the two (password, key card...) or even with both, people misuse security so much (staying logged in, reusing passwords, weak passwords...) that face on its own feels better.

    3- And it can re-authenticate periodically without being too intrusive, which is good, too. It could maybe even detect as soon as the user changes ?

    The one question is , how often do webcams fail, because the day I'm locked out of my computer by a faulty cam, I'll be pissed.

    What the hell happened to fingerprint scanners? I thought they'd be on every keyboard by now and we'd be passed all this password crap.

  • I have a 2004 Toyota Prius with a more or less keyless operation. I just keep the key on my person and as I approach the car, the doors unlock. When I sit down in the car and press a button, the car starts. When I walk away from the car, the car beeps at me to tell me that it's still running and I should turn it off.

    I'm already investigating the possibility of altering the lock of the front door of my house to electronically open as I approach the door and I would like to do the same with my laptop. I think
  • My brother had an Acer with face-based login. I could always get it to let me log in with my face instead (he was around, we were messing with it), no matter how many times he trained it.

      And no, we're not twins. Our faces our similar to some degree, since we're brothers and all, but not that close.
