1. A system to grant access to an apparatus, the system comprising:
- a memory configured to store data representative of a known fingerprint and data representative of a predefined password;
a fingerprint acquisition device configured to sense a fingerprint and to provide data representative of the sensed fingerprint;
a touch screen configured to receive a password and provide data representative of the received password;
a timer configured to measure a time interval between a user-entered geometric pattern when drawn by a user in a specified direction on the touch screen and at least one of the received password and the sensed fingerprint; and
a processing circuit configured to compare the data representative of the sensed fingerprint with the data representative of the known fingerprint, the processing circuit further configured to compare the data representative of the received password with the data representative of the predefined password, and the processing circuit further configured to determine whether the time interval occurs within a predetermined time period.

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.

8. A method to grant access to an apparatus, the method comprising:
-
when a fingerprint of a user is sensed by a fingerprint acquisition device, comparing fingerprint signals representative of the fingerprint sensed by the fingerprint acquisition device with data stored in memory representative of a known fingerprint; when the user enters a password, comparing signals representative of the user-entered password with data stored in the memory representative of a predefined password; and comparing a time elapsed between the user drawing a geometric pattern in a specified direction on a touch screen and at least one of the user entering the password and the fingerprint acquisition device sensing the fingerprint of the user with a predetermined period of time. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method to access an apparatus having a fingerprint acquisition device and a touch screen, the method comprising:
-
when sensing a fingerprint of a user with the fingerprint acquisition device, comparing fingerprint signals representative of the sensed fingerprint with data stored in the apparatus representing a known fingerprint; when receiving a user-entered password at the touch screen, comparing signals representative of the received password with data stored in the apparatus representing a predefined password; and allowing access to the apparatus at least in part on confirming that a time elapsed between a geometric pattern drawn by the user in a specified direction on the touch screen and at least one of the received password and the sensed fingerprint occurred within a predetermined period of time. - View Dependent Claims (16, 17, 18, 19, 20)
