Fwd: Unlocking for Plasma Active 2

[Ivan Cukic]

All those are not really security systems, but rather a fun way to unlock 
stuff.

At first, you think, ok we have 9 digits, so it should be safe enough - 
there are *a lot* combinations you can achieve with 9 digits.

But the problem is that the users will not remember the digits, but the 
shapes - there are a lot less sane shapes than the combinations. Join that 
with the fact that it is a touch screen and that your finger leaves trails 
when dragging, and you have a disaster. :)

The same goes for tangram - nobody will set a random structure as a 
password. although, it wouldn't have the finger trails is the position of 
the pieces is random when the screen is shown.
