PROBLEM TO BE SOLVED: To detect a forged unauthorized card by storing feature data in the magnetic storage part of a card for authentication and collating data read from the magnetic storage part with the data generated by extracting features from image information. SOLUTION: The image read part 31 of an ID card authentication device 13 is constituted of an image scanner or the like for instance, reads a photograph (image) stuck to the photograph sticking part of an ID card and obtains image data. A card reader/writer 33 writes the data to a magnetic stripe or reads the data stored on the magnetic stripe. Also, a feature extraction part 35 extracts the feature data for specifying the image data from the obtained image data. Then, at the time of authenticating the ID card, a control part 37 compares the data stored on the magnetic stripe with the feature data extracted from the photograph stuck to the photograph sticking part of the ID card of an authentication object and checks the propriety of the ID card.
