Motorola Uses NFC To Enable Touch-to-Unlock For Smartphones

colinneagle writes "A lot of people don't password-protect their smartphones, and even those who do employ a simple four-digit passcode to at least keep it a little convenient. Their phones aren't really protected, as the National Institute of Standards and Technology (NIST) recommends a 12-character random password. Those who check smartphones 50 times a day would probably get tired of that. So Motorola developed the Skip, an NFC-based unlocking tool smartphone users can clip to their clothes. Tapping an NFC-enabled phone to the Skip unlocks it. The Skip also comes in sticker form, so users can install one in their cars or at their desks." That's why the muggers want your jacket, too.

    That's a good idea. I think I'll do the same thing with an NFC tag and Tasker. You could also just use any old expired card with an NFC chip in it in your pocket. When I finally get my Pebble watch, I'm planning on having the lock disabled when they're connected to each other.

      Just don't look too hard at that odd-shaped smudge on your screen.

      My screen gets covered with all sorts of oddly shaped smudges just from daily use. I would doubt that forensics have advanced to the point where the greasy smears on my screen protector can be deciphered.

      Especially if you put the area for the entry of that complex gesture right over the part of the screen that has the virtual keyboard.

      Or, how about unlocking by using very specific, complex movements of accelerometer-enabled smartphones, held in a hand. Shaken to a particular beat.

  4. Re:12 digit? by Anonymous Coward · · Score: 2, Interesting

    I wouldn't mind the Skip plus four characters. Multi-factor authentication, so if the phone is stolen, the really long code is required.

    I do this already -- you can split up the screen locker password from the password that unlocks the /data partition, so when the phone first boots, it will ask for the long password, then from there on out, one uses the fairly short screen locker PIN, and too many guesses will cause it to time out.

    It isn't bulletproof, but good enough. I wouldn't mind having a NFC key as an additional layer though. That way, if I have the key with me and lose the phone, I have good confidence that the data on the phone will be out of reach of all but the more well-heeled folks.

    Of course there will be no government-mandated backdoors in this.

    Why would there need to be? It is a matter of controversy whether passwords/phrases are protected from disclosure under the 5th amendment; but physical unlock fobs that can be seized definitely don't enjoy anything more than 4th amendment warrant requirements (and, on a bad day, probably not even that...) A physical fob makes the system markedly more accesssible to authorities, even ones acting within the law.

    In Canada, a password means that the police require a specific warrant to access your phone.

    If it's not protected, they can just put their dick in there if they're arresting you or even just asking you questions.

    Right, if they got your phone, chances are that they took it off of you, and have your Skip-Chip as well.
    (Its actually not really even a fob, its just something to slide over your pants pocket or belt. (Better Picture Here).
    Comes in a set of three, because you WILL soon lose it.)

    But with an APP, and a cheap NFC stickers you can make your own with any android phone that has an NFC chip.

    Some states are Not allowing mobile device searches without a warrant warrants, but that is a trifling impediment. When they confiscate your phone, they will certainly find your "Skip" or they will simply take your phone into their lab an crack it via other means.

    This thing is aimed at the casual user that keeps their phone on their desk, and needs to keep it locked to keep busybodies away from it. Its not meant as protection from the police.
