Preventative steganalysis in wireless visual sensor networks: Challenges and solutions

The goal of preventative steganalysis is to offer a proactive solution against steganography by increasing the steganalyst´s knowledge of the cover-media therefore emphasizing the presence of hidden messages. This paper presents the concept of preventative steganalysis applied to wireless visual sensor networks. By means of the entropy, the uncertainty of the data captured by the network´s camera is reduced, hence reducing the potential embedding capacity and discouraging the use of steganography.
