Comparing Users Handwriting for Detecting and Remediating Unauthorized Shared Access

摘要

A method of using handwriting input on a touch screen device to verify the identity of a user. The user writes a profile word in an input space provided on the touch screen. Features of the handwriting are captured and sent to a server, which stores the data in a data record associated with the authorized user. When a user subsequently writes a challenge word, the handwriting features of the challenge word are compared to the authorized user's handwriting data record and given a rating of similarity. If the rating is within a prescribed range, the user's identity is verified as being the authorized user and permitted to access a given asset. If not, the user's identity is not verified and that user may be denied access to the asset or other action taken. This biometric feature of authentication may be used alone or in a multi-factor authentication environment.
