Pattern unlocking

[Aleix Pol]

It all makes sense, you've looked at the easy part of the problem though.

You want to look at how the authentication actually needs to happen.

At the moment it's PAM who decides if the password is right or not:
- how are you going to turn a pattern into something PAM understands?
- how are users going to enter the pattern they want?
- will the pattern change when the user changes her password?
- has it been done before? how were these being solved then?

See http://www.linux-pam.org/
