US Patent 7154536 Digital camera with a personal identification

A digital camera with a personal identification which is provided with a fingerprint comparator for comparing fingerprint data inputted and sensed by a fingerprint sensor with those already registered with a fingerprint register. An identifier of one of the registered fingerprint data identified with the inputted data is stored in an authorizer of the camera. When a microcomputer of the camera receives an instruction, it accesses the authorizer to execute the instruction if the instruction is intended to handle a frame of image data associated with an identifier stored in the authorizer.
