Secured LSB Modification using Dual Randomness

摘要

Steganography is being used to communicate confidential pieces of information across covert channels as it is less prone to attacks than conventional cryptography methods. It is increasingly used for images or audio files. Least Significant Bit modification is most popular method for steganography through audio files. However, it is open to steganalysis. In this paper, a novel Secured LSB Modification using Dual Randomness method is presented where RSA, XOR operation and most significant bits are used for embedding the secret bits in the sample. The performance of proposed method has been compared with `Enhanced LSB method' and tested on 8-bit audio samples of different sizes. The experimental results validates that the proposed method outperforms along enhanced capacity, robustness, and transparency.
