In recent years it have been witnessed, the rapid development of the internet and telecommunication techniques. But with this development, the security of information is becoming very difficult. To tackle information security problem steganography and cryptography techniques are used. Where cryptography is to scramble the contents of secret message and in steganography the secret message is embedded into the cover medium. In this paper a new technique is discussed by combining both security techniques cryptography and steganography. Firstly information is encrypted by using multiple column transposition cryptography and then this message is hide behind any cover image on LSB 7th bit pixel. This method makes extraction of original message difficult. If hacker will come to know about message hidden in image then will not be able to know original message as it has to be encrypted through cryptography techniques.
