Abstract: A method provides achieving a phone call function of a tablet terminal using a portable terminal. The method includes performing synchronization with the portable terminal when the tablet terminal receives a request for a call connection from a wireless network. After making the call connection to the wireless network, the tablet terminal transmit voice signals received from the wireless network to the portable terminal and transmit voice signals generated by the portable terminal to the wireless network. Upon terminating the call connection with the wireless network, the tablet terminal terminates the communication with the portable terminal.

Abstract: A biometric register includes: a feature extraction unit for performing preprocessing for a fingerprint to extract a feature point m for the fingerprint; a transformation function generation unit for generating a transformation function which is composed of an arbitrary rotation matrix and an arbitrary vector; and a template generation unit for transforming a coordinate of the feature point m using the generated transformation function, and organizing a fuzzy vault using a randomly generated fake feature point and a feature point m1 applied by the transformed coordinate, thereby generating a one-time template.
