First Claim
Patent Images
1. A system comprising:
- a touch screen upon which a user is to enter, by drawing, a geometric pattern in a specified direction to gain access to the system; and
a processing circuit coupled to the touch screen to compare the user entered geometric pattern to a predefined geometric pattern stored in a memory.

Abstract
A method and system for authenticating a user to access a computer system. The method comprises communicating security information to the computer system, and providing the computer system with an implicit input. The method further comprises determining whether the security information and implicit input match corresponding information associated with the user. The method further comprises granting the user access to the computer system in the event of a satisfactory match. When authenticating the user, the method and system consider the possibility of the user being legitimate but subject to duress or force by a computer hacker.

11. A method comprising:
-
receiving a geometric pattern entered by a user on a touch screen of a system to gain access to the system, the geometric pattern being entered by the user by drawing the geometric pattern in a specified direction; and determining with one or more computer processors if the user entered geometric pattern approximates a stored geometric pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system comprising:
-
a touch screen sensitive to a user'"'"'s touch; memory to store at least one user-accessible file; and a processing circuit to compare touch screen input data to data representing a predefined touch screen geometric pattern, the touch screen input data determined from the user'"'"'s touch and representing a touch screen geometric pattern entered by a user by drawing the geometric pattern in a specified direction; wherein the processing circuit is configured to grant the user access to the at least one user-accessible file if the user entered touch screen geometric pattern matches the predefined touch screen geometric pattern. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
