A new algorithm is presented for hiding information in the least significant bits of color images the number of bits used for hiding changes according to pixel neighborhood information where less resemblance between a pixel and its neighbors leads to using more bits for hiding. Steganography papers 2012 there are different file formats used in steganography like text, image, audio and video out of these file formats image steganography is followed in this paper one of the major objective of text steganography with multi level shielding. Steganography is the art and science of hiding a secret message in a cover media such as image, text, signals or sound in such a way that no one, except the intended recipient knows the existence of the data. The cover_medium (and, thus, the stego_medium) are typically image or audio files the aim of our project is to develop “crypt –steganography” that uses cryptography along with genetic algorithm that makes our system more secure and maintains privacy and secrecy of the message.
In computer science, a thorough design phase makes program implementation much easier and more effective students obtain practice with a portion of the design process that may be less exciting, but is just as important as the other steps in the process. The scope of the project is implementation of steganography tools for hiding information includes any type of information file and image files and the path where the user wants to save image and extruded file application gives the screen to select only image file and ask path where user want to save the secrete file.
