Steganography is defined as the study of invisible communication. Steganography usually deals with the ways of hiding the existence of the communicated data in such a way that it remains confidential. It maintains secrecy between two communicating parties. In image steganography, secrecy is achieved by embedding data into cover image and generating a stego-image. There are different types of steganography techniques each have their strengths and weaknesses. Using Steganography techniques on Stego image we can improve the security. For improving second level security we can also apply blowfish algorithm on stego image. so that the result in improvement of security in terms of execution can be achieved.
