Increasing Robustness through Multiple Layers in Audio Steganography

Abstract

‘Increasing Robustness through Multiple Layers in Audio Steganography’ is a project relating to cryptography that uses multiple cryptographic methods under a project. The multiple cryptographic method ensures the complexity of decryption. This cryptographic method also uses multiple layers for each cryptographic method. The system uses three blocks for encryption namely cipher-text, text steganography and audio steganography. The first two blocks can further be into number of layers. The decryption is also achieved through the same reverse process. Further details of multiple layers will be discussed in the rest of the paper. In this project, we wxplore the potential of steganography in increase of robustness by introducing multiple cryptographic techniques in an encryption of text file so that it becomes difficult to decrypt it. We use two algorithms for the encryption, they are LSB and MSB embedding technique. _______________________
