A Fact Obscuring Setup Using Guarded Majority Vote Strategy

In steganography, the detectability of hidden data in a stego object is mostly influenced by four basic ingredients; the cover object, the selection rule used to identify individual elements of the cover that might be modified during embedding, the type of embedding operation that modifies the cover elements and the number of embedding changes (related to the message length). The information hiding deals with distortion reduction using steganography and security enhancement using cryptography. Distortion reduction is done using Tree Based Parity Check which uses majority vote strategy. The Tree Based Parity Check is very optimal for cloaking a message on image. The proposed majority vote strategy results in least distortion. The SHA-1 algorithm is implemented for security enhancement.
