SYSTEM AND METHOD FOR FACE MOTION DETECTING RECOGNITION USING ACCELEROMETER SENSOR

摘要

A system and a method for recognizing/authenticating face motion with an acceleration sensor are provided to enhance security/stability by performing the authentication operation in reflection of a user opinion through a two-axis acceleration sensor and reducing unnecessary authentication operations and errors due to automation of the authentication operation. An authentication system includes a security server, a ZigBee transceiver transmitting a signal transmitted to request authentication to the security server, and an authentication server authenticating the security terminal. The security terminal includes a two-axis acceleration sensor(211) recognizing the face motion of the user, a ZigBee communicating module(214) wirelessly communicating with the ZigBee transceiver, and a CPU(212) performing a predetermined authentication protocol by determining the face motion based on a sensing value of the two-axis acceleration sensor. The security terminal includes a power managing module(216) controlling power supply of the security terminal, a speaker(213), and an encoding processor(215) performing RSA(Rivest, Shamir, and Adelman) encoding according to control of the CPU.
