A comparative evaluation for digital image watermarking techniques in wireless image sensor networks
Wireless sensor networks have emerged as the major criteria that enable the Internet of things evolution. In which, wireless image sensor network have wide application range from special domain to civilian and scientific domain thus it is attracted a lot of research. Since security is of the crucial importance for wireless sensor networks, there are existed several authentication techniques for digital right management, and watermarking is a promising approach for ensuring a part of communication security in these networks due to its popular use and lightweight. To develop a security solution based on this approach, the digital image watermarking techniques need to be considered in different aspects of performance. The paper presents a comparative evaluation on error performance of major digital image processing techniques for JEG/JPEG2000 standard image and its embedded watermark images in a typical wireless image sensor networks. Moreover, a watermark detection probability with varied transform methods is delivered to recognize how attack possibilities. Numerical results will show a best choice of embedded watermark transform method in wireless image sensor networks.
