SMART CARD WITH OTP INCLUDING IRIS IMAGE INFORMATION

PURPOSE: A smart card with an OTP(One-Time Password) including iris image information is provided to improve security by combining bio information with the OTP and comparing iris image information obtained through a camera with iris image information stored in a memory of the smart card. CONSTITUTION: An iris image template(14) is stored in a memory for confirming a user of a smart card. An OTP unit(11) generates an OTP on a bracket or a terminal including a card reader and a camera by using a hash function using an iris image template taken by the camera as a variable. The memory includes a program for generating the OTP. A microprocessor executes the program stored in the memory. A determining unit compares the iris image template taken by the camera with an iris image template registered in the smart card reader to determine an owner of the smart card.
