Abstract
A system requires a user to enter a geometric pattern on an interface device to gain access to the system. After the correct geometric pattern is entered, a timer times a duration before an authenticating password is subsequently entered by the user. If the duration exceeds a predetermined length of time, access to a set of one or more files is at least temporarily prevented. If the user enters the authenticating password before the duration exceeds the predetermined length of time, access to the set of one or more files is granted.
