Steganography algorithm using encrypted secret message

Security is the major issues for transmission of messages or any media files containing critical information. In this paper we are using LSB method and have modified the idea of Play fair method into a new platform where we can encrypt or decrypt any file. A secret key is entered by the user during encryption which is used at time of decryption. In this paper we propose technique for encryption of text into a cover image. For hiding secret message in the coverfile we have inserted the 8 bits of each character of encryptedmessage file in 8 consecutive bytes of the cover file. We proposethat our new method could be most appropriate for hiding anyfile in any standard cover file such as image, audio, video files. Because the hidden message is encrypted hence it will be almostimpossible for the intruder to unhide the actual secret messagefrom the embedded cover file. This method may be the most Secured method in digital water marking.
