Abstract: The network provides a method of communication to distribute information to the multitude. With the growth of data communication over computer network, the security of information has become a major issue. Cryptography and steganography are two different data hiding techniques. The science of securing a data by encryption is Cryptography whereas the method of hiding secret messages in other messages is Steganography, so that the secrets very existence is hidden. The term Steganography describes the method of hiding cognitive content in another medium to avoid detection by the intruders. Steganography hides messages inside some other digital media. In the process a message is first encrypted using transposition cipher method and then the encrypted message is embedded inside an image using LSB insertion method. The combination of these two methods will enhance the security of the data embedded. A comparative analysis is made to demonstrate the effectiveness of the proposed method by computing Mean square error (MSE) and Peak Signal to Noise Ratio (PSNR). We analyzed the data hiding technique using the image performance parameters like Mean, Entropy and Standard Deviation. The main objective in this paper is to provide resistance against statistical attacks and visual as well as high capacity.
