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. ## Claims ### Claim 1 An apparatus comprising: a touch screen sensitive to a user's touch; a fingerprint acquisition device to sense a fingerprint; and a user access system comprising a processing circuit coupled to the touch screen and the fingerprint acquisition device, wherein the processing circuit is configured to: permit viewing of a first set of applications on the touch screen without permitting an ability to view a second set of applications in response to a user performing, on the touch screen, a geometric pattern that is detected by the user access system; permit viewing of the second set of applications on the touch screen in response to the user entering, on the fingerprint acquisition device, a fingerprint that is determined by the processing circuit to match a known fingerprint; and permit viewing of the second set of applications on the touch screen in response to the user entering, on the touch screen, a password that is determined by the processing circuit to match a known password. ### Claim 2 (depends on 1) The apparatus of claim 1 wherein a direction of the user-performed geometric pattern is detected by the user access system. ### Claim 3 (depends on 1) The apparatus of claim 1 wherein the geometric pattern is a line, a circle, or a rectangle. ### Claim 4 (depends on 1) The apparatus of claim 1 wherein the processing circuit is further configured to receive data representative of the user-performed geometric pattern as a first user-interactive step after the apparatus is deactivated and reactivated. ### Claim 5 (depends on 1) The apparatus of claim 1 wherein the processing circuit is further configured to receive data representative of the user-performed geometric pattern and use the data representative of the user-performed geometric pattern to detect the user-performed geometric pattern. ### Claim 6 A method comprising: permitting, with an access system of an apparatus comprising computer hardware and memory storing applications, viewing of a first set of stored applications without permitting an ability to view a second set of stored applications when the computer hardware detects a geometric pattern performed by a user on a touch screen of the apparatus; and permitting, with the computer hardware, viewing of the second set of stored applications when at least a first satisfactory match or a second satisfactory match occurs, the first satisfactory match occurring when the computer hardware determines that a fingerprint entered by the user on a fingerprint acquisition device matches a known fingerprint, and the second satisfactory match occurring when the computer hardware determines that a password entered by the user on the touch screen matches a known password. ### Claim 7 (depends on 6) The method of claim 6 wherein the geometric pattern has a predetermined direction. ### Claim 8 (depends on 6) The method of claim 6 further comprising detecting with the computer hardware, a direction of the user-performed geometric pattern. ### Claim 9 (depends on 6) The method of claim 6 wherein the geometric pattern is a line. ### Claim 10 (depends on 6) The method of claim 6 further comprising receiving data representative of the user-performed geometric pattern as a first user-interactive step after the apparatus is deactivated and reactivated. ### Claim 11 An apparatus comprising: a touch screen sensitive to a user's touch; a device to sense a physical feature of a user; memory to store one or more applications; and an access system comprising a processing circuit coupled to the touch screen, the device, and the memory; wherein the access system permits viewing of a first set of applications of the one or more applications without permitting an ability to view a second set of applications of the one or more applications, based upon the user performing, on the touch screen, a geometric pattern that is detected by the access system; and wherein the access system permits viewing of the second set of applications based upon one or more of the device sensing a physical feature that is determined by the access system to match a known physical feature, and the user entering, on the touch screen, a password that is determined by the access system to match a known password. ### Claim 12 (depends on 11) The apparatus of claim 11 wherein the physical feature is a fingerprint, a retina, or a voice. ### Claim 13 (depends on 11) The apparatus of claim 11 wherein a direction of the user-performed geometric pattern is detected by the access system. ### Claim 14 (depends on 11) The apparatus of claim 11 wherein the user-performed geometric pattern is a line, a circle, or a rectangle. ### Claim 15 (depends on 11) The apparatus of claim 11 wherein the access system receives data representative of the sensed physical feature and uses the data representative of the sensed physical feature to determine if the sensed physical feature matches the known physical feature. ### Claim 16 An electronic device comprising: a touch screen; a fingerprint acquisition device; memory to store one or more applications; and a user access system comprising a processing circuit coupled to the touch screen, the fingerprint acquisition device, and the memory; the user access system to permit viewing of a first set of applications of the one or more applications without permitting an ability to view a second set of applications of the one or more applications in response to a user performing, on the touch screen, a geometric pattern that is detected by the user access system; and the user access system to permit viewing of the second set of applications in response to at least one matching event, the at least one matching event selected from the group consisting of a match, determined by the user access system, between an acquired fingerprint and a known fingerprint, and a match, determined by the user access system, between a password entered by the user on the touch screen and a known password. ### Claim 17 (depends on 16) The electronic device of claim 16 wherein the user access system detects a direction of the user-performed geometric pattern. ### Claim 18 (depends on 17) The electronic device of claim 17 wherein the user access system determines if the detected direction matches a specified direction. ### Claim 19 (depends on 16) The electronic device of claim 16 wherein the user access system receives data representative of the user-performed geometric pattern as a first user-interactive step after the electronic device is deactivated and reactivated. ### Claim 20 (depends on 16) The electronic device of claim 16 wherein the user access system receives data representative of the user-entered password and uses the data representative of the user-entered password to determine if the user-entered password matches the known password.
