Abstract
An individuality discriminating system wherein analog signals of a human individual picture are converted to digital signals according to brightness of the picture, and such digital signals are stored as individual picture data in an integrated-circuit (IC) card as compressed, with picture elements other than changed ones in the picture treated as zero picture elements, while in using the IC card by its bearer the thus stored data are read out of the card as expanded and analog-converted for display on a monitor. Since the picture data are compressed to remarkably reduce code volume upon the storing in the card, the individuality discrimination can be realized practically precisely and effectively reliably through an investigators's comparison with eyes of the thus displayed picture with a directly viewed or monitored picture of the bearer.
