Abstract
Lin and Tasi, Yang et al., and Chang et al.’s meaningful secret sharing schemes provided authentication mechanisms but none included a remedy ability that would cause the secret image never to be completely obtained while some information of the stego-images are losing or tampering with. This paper proposes a meaningful secret-sharing scheme which includes both authentication and remedy abilities that allow for detection of the corrupted area and use of the hidden information to repair the secret image with reasonable visual quality. In comparison with previous schemes, this approach results in superior visual qualities of the stego-images by an average of more than 3 dB.
