Abstract :
In this paper, we propose an enhanced authentication scheme that aims at the detection of stego-image preventing the fake share offers from the share-holder. Inspired by the past one study of Wang et al. scheme, the secret reconstruction is not complete in the course of shadow stego-images upon the secret sharing systems. Besides, the PSNR evaluations to the embedded images are furthermore superior to the past studies upon our revised algorithms. In other words, the secret embedding and reconstruction is definitely fulfilled upon the secret sharing systems. The qualities of the stego-images also do meet the requirement of steganography in better fidelity upon human vision systems.
