Abstract: In this paper, we enhance the security for the data by hiding the message using steganographic technique. Initially the given message is taken as input and we generate digital signature using MD5 algorithm. After generating the signature we conceal the given message using steganography. Now, the message which is hidden along with the digital signature is sent to the receiver. The receiver applies the steganographic technique to retrieve the message and then verifies the digital signature.
