Neha Narula, Deepak Sethi, P.p. Bhattacharya . Transmission of Secured Image using DWT-SVD Technique for Applications in Wireless Sensor Network. International Journal of Computer Applications. 119, 6 ( June 2015), 11-18. DOI=10.5120/21071-3745
Wireless sensor networks hold the promise of facilitating large-scale and real-time data processing in complex environments. These networks are used in a variety of applications including military, surveillance, industry and health systems. Sensors used in these applications can be susceptible to various types of attacks such as data modification, data insertion and deletion, or even physical capture and sensor node replacement. Therefore, security is a critical issue that must be resolved. This paper presents the transmission of secured image using DWT-SVD image hiding technique. Initially, both the carrier image and the secret image are decomposed according to DWT (Discrete Wavelet Transform) and then the secret image is embedded in singular values of the carrier image by applying SVD (Singular Value Decomposition). An Energy saving greedy algorithm is applied for routing the resultant secured image in the form of packets. Experimental results and performance analysis demonstrate that the proposed scheme can protect the sensitive information without affecting the transmission and usability of the ordinary data.
