In this paper, we propose a novel watermarking-based secure image acquisition scheme for multimedia sensor networks (MSNs), which provides support authentication and restoration. the proposed scheme, node groups frames. Two successive frames compose non-overlapping restoration group. The watermarking bits, are version of down sampling image, computed from first reversibly embedded into second image. sink does verification by reversible watermark. Compared to previous work, our approach can not only implement but also improve quality. Experimental results show that achieve gains in terms packet loss tolerance
