Title: A technique for sharing a secret color image
Inventor: JANG JEN-CHENG
IPC: H04N1/00
Filed: 1999-07-22
Granted: 2001-03-01
Abstract: The present invention is related with ""Information Security"". A color image hiding technique developed based on Visual Cryptography is hereby proposed. The technique can very effectively hide a secret color image between any two randomly selected color images having certain significance. In other words, the two color images are used to camouflage the secret image and, therefore, may individually be owned by two participants sharing the secret. When the secret image needs to be restored, the two participants need only to provide each of the camouflaging image them possesses before. By means of simple overlapping and rather simple calculations, the secret image can be restored from the two camouflaging images. The present invention has a high security. It is impossible to restore the secret image if any one of the camouflaging images is not available. Note: The present invention is in the area of ""Information Security"". The related professional advise or assistance may be obtained from ""Information Security Society of the Republic of China"".
