An iris identification system integrated USB storage device includes a USB interface unit which includes a USB port, and a USB controller adapted to control a data transmission between the USB port and the Data Storage; a Data Storage which stores data inputted from the computer through the USB interface unit; a Data Storage Controller which allows an access from the computer to the Data Storage through the USB interface unit or disconnects the access; and an Iris Identification Device which creates an iris code from an iris image inputted from an iris photographing camera, compares the previously stored original iris code with the created iris code, and allows the Data Storage Controller to be an access allowance state or an access disconnection state.
