Fast Decoding Method for On-line Visual Secret Sharing by Parallel Processing Approach

The visual secret sharing is a method of safely transmitting and storing images. There are a lot of papers emphasis it's safety and decoding with pure eye. But the quality of recovery image is not good. However, it is a good property to prevent attack from robot by recognizing the secret image. It is necessary to decrease the decoding time when apply visual secret sharing in online application. Base on parallel computation, this paper propose a solution to increase the decoding efficiency.
