In covert communication, Information hiding is rapidly gaining momentum. There are many sophisticated techniques being developed in steganography. There is a need of universal method to detect hidden image. We have proposed a Universal method to detect hidden message using Histogram, Discrete Fourier Transform and SVM (UDHDS). When compared to cover image(More)
Information hiding for covert communication is rapidly gaining momentum. With sophisticated techniques being developed in steganography, steganalysis needs to be universal. In this paper we propose Universal Steganalysis using Histogram, Discrete Fourier Transform and SVM (SHDFT). The stego image has irregular statistical characteristics as compare to cover(More)
The major concern is on energy-efficient routing in wireless sensor networks. Existing routing schemes assigns energy-related costs and obtain the shortest paths. Maximum achievable lifetime and optimal link cost are low in the existing routing schemes. The best performance is achieved by obtaining the shortest path in distributed routing algorithm. The(More)
