SMART CARD WITH SIGN PAD, AND METHOD OF USER AUTHENTIFICATION

摘要

PURPOSE: A smart card and user authentication method is provided to improve recognition rate and increase security by storing signature information and signature information algorithm. CONSTITUTION: A signature information input unit(15) receives sign information of user. A memory(12) stores sign recognition algorithms. A controller(11) recognizes an inputted sign information based on a fixed recognition of signature algorithm by user among recognition of signature algorithms and performs user authentication. The sign information input unit is an input panel inputting the sign information. The sign information input unit extracts a handwriting sign image and transmits an image data to a controller.
