A spatial domain secret image embedding technique with image authentication feature

In practical applications, it is required to provide a means to authenticate an information-embedded image such that its integrity can be guaranteed. However, conventional studies generally consider image hiding and image authentication as two different tasks. When both are required, the secret image and a fragile watermark are separately embedded into a cover image. In this paper, to address this issue, we propose a spatial domain image embedding scheme that can embed rich pictorial information and fragile watermark simultaneously into a cover image with the same technique to reduce the complexity and improve the efficiency.
