SYSTEM FOR PERSONAL AUTHENTICATION AND ELECTRONIC SIGNATURE USING IMAGE RECOGNITION AND METHOD THEREOF

摘要

A system and a method for authenticating a user and an electronic signature with image recognition are provided to realize a safe and stable authentication system in a mobile terminal by using a portable image medium and a transmitter. A mobile terminal(10) captures and transmits the image used as an authentication image by user operation. An image recognition server(20) estimates projection transformation relation between an image stored in a database and the image received from the mobile terminal by extracting/comparing SIFT(Scale Invariant Feature Transform) feature vector from the received image with the SIFT feature vector of the authentication images stored in the database, and using position relation of the SIFT feature vectors. An authentication server(30) transmits a result to the mobile terminal by determining the unique image of the user and authenticating the user/electronic signature based on the estimated projection transformation relation.
