Data protection based on multifunction digital watermark in wireless sensor network

In this paper, we at first specially present a framework of transmitted data protection based on multiple-function digital watermarking in wireless sensor network (WSN). And we provide the security features of transmitted data protection and the corresponding properties of digital watermarking in WSN. As an example, we introduce an efficient watermarking-based data protection scheme. Our data protection scheme utilizes self-embedding watermarking for image data to provide content audit, and support authenticity and integrity for image content in WSN. Moreover, our scheme also supports the copyright protection of image by self-embedded technology. That is, we integrate image content authentication, integrity audit service and copyright protection through a multiple function self-embedded watermarking scheme, which is the advantage of our scheme.
