Abstract: Providing security to the data is a very important aspect in communication system. The importance of security lies in each and every region like e-commerce, industry, education and data ware house. The two main methods used for protecting data from an intruders while transferring over an open channel network are cryptography and steganography. The encryption of data is done in cryptography and steganography hides the secret image in a cover image. In this paper we are encrypting the data with a new cryptographic algorithm called affine cipher. The alphabets and special characters are transformed into numerical values equivalent to them. The encrypted data is embedded into a cover image which is binded with a key generated from an binary image in order to provide much more security. The system using this process has the better security in transferring the secret messages from sender to the receiver through public channels.
