Estimating the term…
The present invention provides a method to validate the identity of a user of a mobile computer, especially a laptop computer or a notebook computer, which comprises an integral pointing device. The method is characterized in that the integral pointing device of the mobile computer is used as signature input device to identify a signature of the user. The present invention further provides a new mobile computer, especially a laptop computer or a notebook computer, which comprises an integral pointing device being able to record the signature of a user sufficiently accurate to allow signature recognition and thus user identification. Preferably the integral pointing device is able to detect multiple pressure levels for dynamic signature recognition.
A method to validate the identity of a user of a mobile computer comprising the steps of:
A mobile computer, comprising an integral pointing device being sensitive to a position of a manually driven input means and being able to track the position of said manually driven input means on said integral pointing device, characterized in that said integral pointing device outputs digital data in response to a signature of said user responsive to movement of said manually driven input means on said integral pointing device, and in that said mobile computer includes evaluation means for evaluating said digital data for validating the identity of said user.
A computer program product stored in the internal memory of a digital computer, containing parts of software code to execute a method to validate the identity of a user of a mobile computer comprising the steps of:
