IMAGE PROTECTION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image protection system and method coupling a compression technique and an encryption technique. SOLUTION: The image protection system includes at least an image compression/encryption device 210 composed of a compression unit 213, an encryption unit 214 and an image composing unit 215. The compression unit 213 separates an image 240 into base image data and auxiliary image data according to the predetermined compression technique, and compresses the base image data to compressed base image data according to the compression technique. The encryption unit 214 encrypts the auxiliary image data to an auxiliary image data cipher. The image composing unit 215 composes the compressed base image data and the auxiliary image data cipher into a protected image corresponding to the source image 240. COPYRIGHT: (C)2005,JPO&NCIPI
