 note = {This paper describes a new individual identification system employing a novel application of the PC/SS scheme.Since the proposed system requires no magnetic information, it is robust to various changes in environment.Moreo ver, it is applicable to contemporary identification systems as an officer identifies one’s face with the card’s portrait at immigration. In addition, cooperation with existing identification systems using magnetic information and this proposed system provides more secure identification.The proposed system embeds a cardholderrelated information that forms a watermark generated by the modulating manner of the PC/SS scheme into cardholder’s portrait printed on the card using a simple watermarking scheme also proposed in this paper.Exp erimental results show that the proposed system extracts embedded information correctly as its fundamental ability.F urthermore, various properties of this system have been investigated, and it has been found that the spatial resolution of scanners is the most dominant to the performance of the proposed system., Copyright notice. c2000 IEICE All rights reserved.
