This application is a security lock application to track the numbers randomly allocated on the matrix to unlock.The default pattern lock application is lack of security against the fingerprint trace reading and the peek over the shoulder because the unlock pattern is not variable.This application enhances the security by combining the number password with the pattern lock. The user track the numbers assigned on each cell of the matrix to form the password which the user set in advance.Because of the random number assignment, the unlock pattern varies every time when the lock screen is shown.
