STEGNOGRAPHY ENCRYPTION SCHEM USING FINITE STATE MACHINE AND CONCATENATION

S teganography is the technique of hiding confidential data with in any media. Steganography and cryptography are used to protect data but the major difference between the two is in the appearance in the processed output. In cryptography the output is scrambled, whereas in steganography it is not apparently visible. Automata theory is the study of abstract computing devices or machines. In computer science we find many examples of finite state system, as a useful design tool for these systems.
