Meaningful Secret Image Sharing with Uniform Image Quality

In meaningful secret image sharing (MSIS), a is divided into n shadows. Each shadow and similar to the corresponding cover image. Meaningful shadows can reduce suspicion of attackers in transmission facilitate management. Previous MSIS schemes always include pixel expansion, cross-interference from different may exist when images are extremely unnatural with large black white blocks. this article, we propose an uniform quality. A threshold t set determine absolute salient regions. More identical bits allocated according saliency values region, which improve addition, new allocation strategy also adjusts randomness images, generating quality avoiding between Experimental results show effectiveness our proposed scheme.
