Patent ID: 8121359

Claim:
A fingerprint identification system of an electronic device having a touch panel, the system comprising: a non-transitory computer readable medium that stores original fingerprint characteristic values of authorized users of the electronic device; an obtaining module configured for receiving pressed signals from the touch panel, and obtaining a voltage graph of a fingerprint of a user logging into the electronic device from the pressed signals; a detecting module configured for detecting fingerprint characteristic points in the voltage graph of the fingerprint, and computing fingerprint characteristic values according to the detected fingerprint characteristic points; a determining module configured for determining if the computed fingerprint characteristic values match the original fingerprint characteristic values of an authorized user in the non-transitory computer readable medium; and a validating module configured for validating an identification of the user logging in if the fingerprint characteristic values match the original fingerprint characteristic values of the authorized user in the non-transitory computer readable medium wherein the original fingerprint characteristic values and the fingerprint characteristic values comprise a characteristic point count, characteristic point coordinates, a linked shape of the characteristic points, and relative positions between adjacent characteristic points.
