A hybrid technique for data embedding over wireless sensor networks based on cover generation through variance

Abstract

In today's digitized era almost all data is transferred digitally which is very easy and advantageous but it also has some shortcomings i.e. the security of this data is very important. With the advent of wireless sensor networks in military regions, security of this secret data is very crucial. So Security technique such as steganography can provide the need to be a lightweight and energy efficient technique without being effected by attacks. In this paper, two state of the art steganography techniques are studied which have been applied over speech data and image data respectively, and modified them in order to use them in network steganography for wireless sensor networks. Energy, throughput, Delay, Mean squared error, Peak Signal-to-noise ratio and absolute mean difference as detectability parameter are evaluated and compared with the already available techniques of steganography and wireless sensor network and the hybrid technique performed well and have potential to be applied over wireless sensor networks for military application.
