In this paper the concept of cryptography and steganography are combined to perform a powerful encryption.Here we propose a novel approach where a duel encryption methodology has been implemented.In the first level of encryption a pattern matching algorithm has been employed to encrypt the text message in terms of their positional value.In second level, the conventional LSB method has been used to embed the positional value in the cover file.Such a duel encryption method will ensure data security in an efficient manner.Finally the performance of the proposed method is evaluated in terms of means square error (MSE) and signal to noise ratio (SNR).A comparison has been carried out with conventional LSB method.The experimental results and the comparisons demonstrated that our algorithm is highly efficient in terms of encryption and the capacity size of the text.
