Privacy preserving data mining using visual steganography and encryption

摘要: Steganography is the process of hiding a secret message within an ordinary & extracting it at its destination. Visual steganography one most secure forms available today and highly suited for image files. The scope this paper to combine cryptography properties in such way make harder retrieve message. In work, sliced, sliced images are stored upon match with search string query original retrieved by merging individual randomly ordered slices regular manner. slicing ensures privacy preserving thread based mining reduces time complexity algorithm.
