IMAGE INFORMATION SECURITY METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image information security method capable of protecting image information (secret image) by forming the image information (secret image) to be protected as a computer hologram, embedding the computer hologram into a dummy image (cover image) to form an embedded image, and reproducing the secret image from the embedded image. SOLUTION: The image information security method comprises preparing the secret image which is a target for protection (a step 101); preparing the cover image to be embedded with the secret image prepared in the step 101 (a step 102); synthesizing the secret image prepared in the step 101 with the computer hologram (a step 103); embedding the computer hologram synthesized in the step 103 in the cover image prepared in the step 102 (a step 104); generating the embedded image (a step 105); and reproducing the secret image from the embedded image generated in the step 105 (a step 106). As a result, the secret image can be taken out and verified. COPYRIGHT: (C)2007,JPO&INPIT
