Method for authenticating a user using biometrics and digitized handwritten signature, and system implementing the same

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

• a first procedure that is associated with fingerprint verification, and that includes a step of, by a biometric stylus that stores a piece of encrypted identification data and a fingerprint template of the user therein and that is capable of fingerprint recognition, encrypting the encrypted identification data to generate a piece of first verification data when determining that a fingerprint captured by the biometric stylus matches the fingerprint template of the user, wherein the encrypted identification data is related to an identity of the user;
• a second procedure that is associated with handwriting input, and that includes steps of:
• by a handwriting input device, receiving the first verification data from the biometric stylus, and decrypting the first verification data to obtain the encrypted identification data;
• by the handwriting input device, acquiring a handwriting pattern that is inputted on the handwriting input device through touch sensing using the biometric stylus;
• and
• by the handwriting input device, encrypting the encrypted identification data and the handwriting pattern to generate a piece of second verification data;
• and
• a third procedure that is associated with user identification and that includes steps of:
• by a verification server, receiving the second verification data from the handwriting input device, and decrypting the second verification data to obtain the encrypted identification data and the handwriting pattern;
• and
• by the verification server, decrypting the encrypted identification data to obtain a piece of user identification data for verifying the identity of the user when determining at least that the handwriting pattern matches a handwriting template of a piece of personal identification data stored in the verification server.
