Abstract

A method is provided for authenticating a user using biometrics and digitized handwritten signature. A verification server uses a data identifier to find a corresponding piece of personal identification data. A user uses a biometric stylus and a handwriting input device to create a handwriting pattern; meanwhile, the biometric stylus acquires fingerprint data of the user. The handwriting input device transmits the fingerprint data and the handwriting pattern to the verification server. The verification server verifies the handwriting pattern and the fingerprint data using a handwriting template and a fingerprint template included in the personal identification data thus found, and obtains user identification data for verifying an identity of the user from the personal identification data when the handwriting pattern and the fingerprint data are successfully verified.

Dependent claims

A method for authenticating a user using biometrics and digitized handwritten signature, comprising:

a first procedure that is associated with data screening, and that includes a step of, by a verification server, receiving a data identifier and finding a piece of personal identification data that corresponds to the data identifier from a database;
a second procedure that is associated with fingerprint acquisition, and that includes a step of, by a biometric stylus that includes a fingerprint sensor, sensing a fingerprint of the user to acquire a piece of fingerprint data, and generating a piece of first verification data that is encrypted and that includes the fingerprint data;
a third procedure that is associated with handwriting acquisition, and that includes steps of:
by a handwriting input device, receiving the first verification data from the biometric stylus;
by the handwriting input device, acquiring a handwriting pattern through touch sensing;
and
by the handwriting input device, generating a piece of second verification data that is encrypted, and that includes the first verification data and the handwriting pattern;
and
a fourth procedure that is associated with user authentication, and that includes steps of:
by the verification server, receiving the second verification data from the handwriting input device;
by the verification server, decrypting the second verification data to obtain the first verification data and the handwriting pattern;
by the verification server, decrypting the first verification data to obtain the fingerprint data;
and
by the verification server, generating an authentication success message that indicates a success in user authentication when determining at least that the handwriting pattern matches a handwriting template of the personal identification data found in the first procedure, and that the fingerprint data matches a fingerprint template of the personal identification data found in the first procedure.
