SYSTEM AND METHOD FOR ENCODING AND AUTHENTICATING A DIGITAL IMAGE |
摘要 |
An encoding apparatus partitions a digital image into multiple regions for subsequent encoding. A first encryption code is associated with a first region, a second encryption code is associated with a second region and the first code, and a third code is associated with the first code, the second code and a third region. An authentication apparatus authenticates the digital image in an inverse process. |
