WhisperCore Clears The Finger Smudges From Your Phone's Screen For Increased Security

Android only: Android's built-in lock screen patterns are great for securing your phone, but they leave finger smudges on your screen that give away your pattern. Security app WhisperCore fixes this problem by making you wipe away those smudges to unlock your phone.

While you could always just wipe off your screen every time you lock it back up, it's easy to forget and unknowingly give up your lock pattern. WhisperCore solves this problem by presenting you with a pattern or PIN unlock screen, then forcing you to wipe your finger down the screen before it'll unlock. This final wipe will erase all traces of your PIN or lock pattern, so no one will be the wiser, and you'll never forget to cover your tracks.

WhisperCore is free, but unfortunately only available for the Nexus One and the Nexus S. They're looking to support more devices soon, though, and it was so clever we just had to post it. Furthermore, it's a good reminder that Android's pattern unlock isn't very secure, and you'll always want to wipe those smudges off your phone when you put it away.

    My pin is 1111, it is easy to remember, quick to enter, just as hard to crack from a brute force perspectivee as any other 4 digit code, and by only tapping 1 number, people have to guess the number of digits, or would fail to detect it as the code (only 1 imprint)

      Agree with Ads. Most times simply having a password is enough disincentive to thwart mischief makers.

      My laptop password for a while was asdfghjkl;'

      Just swipe your finger along the middle row and you enter the password and hit the enter key in one move!

      Not very secure password, but neither is the data. If someone was determined enough to access my data they could just remove the hard drive and get what they need.

    >just as hard to crack from a brute force perspectivee as any other 4 digit code

    Lol. Most brute force approaches would guess that one first.

    Btw, rather than wiping your screen physically, wouldn't it be better if the PIN entry screen rearranged the digits randomly, like the ingdirect login page?

      I agree. The best would be a pin that the numbers jumble around each time.
      Hey, I now have few more ideas jumping into my head. I wonder how hard it would be to build something like that?

      Brilliant Idea!

    I think this rather underplays what whispercore does - it offers probably the most secure android experience you can have right now. It offers full disk encryption, and installing 'whispermonitor'
    also gives you a rather nice firewall.

    This new update to it doesn't add too much, to be honest. The Screen Smudge problem is only an issue if people are simply typing in their pin and relocking the phone. All you have to do is open an app and use it for a second and you've rendered any smudges useless.
