RAND - STEG: an integer wavelet transform domain digital image random steganography using knight's tour

Abstract

In recent times, the use of Internet for data exchange has increased to a great extent. Steganography, cryptography and watermarking are the methods to transfer the data with high security. In this paper, a steganography method with constant bit embedding and adaptive bit embedding in Haar Integer Wavelet Transform domain has been proposed. The adaptive bit embedding provides more security than the constant bit embedding. Here, a mathematical model for Knight's Tour is developed, which adapts random traversing inside the wavelet coefficients to increase the security further. In this proposed work, multiple security is ensured by formulating Knight's Tour algorithm for random traversing and selecting the order of sub-bands to provide high capacity, security and robustness.

QR-like Secret Data Hiding in Integer Wavelet Transform Domain Images

“…The most secure one-on-one communication technique is steganography [8][9][10][11]. The principle behind steganography simple, the unauthorized party must not have a clue of what is being transferred.…”
