Abstract:
1. A method for improving security of a security token comprising the steps of: detecting a bioelectrical signal of cardiac muscle of a host user; extracting a bioelectrical feature parameter from the bioelectrical signal of the cardiac muscle; processing the bioelectrical signal to produce a bioelectrical feature vector of the cardiac muscle; and allowing the host user to access data stored in the security token after verifying the host user, and the host user operating on the stored data by reading, writing, and encrypting/decrypting; wherein detecting the bioelectrical signal of the host user further comprising the steps of: wherein the previously specified conditional value is a threshold, the bioelectrical signal of the host user being verified is compared with the threshold, and the host user is a valid user if the comparison result is greater than or equal to the threshold; wherein processing the bioelectrical signal to produce the bioelectrical feature vector further comprising the steps of: wherein extracting the bioelectrical feature parameters from the handled bioelectrical signal further comprising the steps of:
