In today’s scenario security of data is very big challenge in any communication. Numerous data security and hiding algorithms have been developed in the last decade. The Digital image Steganography is science of hiding sensitive information in another transmission medium to achieve secure and secret communication. In this paper we present the dual layer of security to the data, in which first layer is to encode data using Least Significant Bit image steganography method and in the second layer encrypt the data using Advance Encryption Standard Algorithm. Steganography does not replace the encryption of data, instead it provides extra security feature to it. In our work secret text message is hiding behind the digital image file and this image file is then encrypted using AES encryption algorithm.
