Data hiding is an emerging field of research for secure data transmission over internet, ensuring ownership identification and copyright protection. A couple of techniques have been proposed based on pixel value differencing (PVD) and eight queens' solutions. In this paper, a new data hiding method based on inter-block difference in eight queen's solutions(More)
In this paper we present a reversible image steganography technique based on Slantlet transform (SLT) and using advanced encryption standard (AES) method. The proposed method first encodes the message using two source codes, viz., Huffman codes and a self-synchronizing variable length code known as, T-code. Next, the encoded binary string is encrypted using(More)
Grid computing is a high performance computing environment to solve larger scale computational demands. Grid computing contains resource management, task scheduling, security problems, information management and so on. Task scheduling in an important aspect of distributed computing. As grid computing is a form of distributed computing with heterogeneous(More)
