Sequential Multiple LSB methods and real-time data hiding: variations for Visual Cryptography ciphers

Abstract

In this paper, a general model approach of real-time data hiding and watermarking for image, video and audio communications is proposed. The aim is the development of security robustness variations and data-rate (capacity) extensions of Steganography fast schemes for RT (real time) or NRT (near real time) image, video and audio media communication and data hiding, with no significant distortion of the medium. Additionally, this paper includes the proposal of specific case models such as Steganography of the total of Visual Cryptography schemes of black and white images. Influenced by our survey on Spatial Domain Steganography techniques such as Multiple LSB (Least Significant Bit) algorithm, Matrix Embedding and Parity Coding, a new potential method is introduced called in brief from now on SMLSB (Sequential Multiple LSB) method comparing other respective methods and algorithms researched, SMLSB is a different approach on real-time and non-real-time data hiding, which gives an advantage of robustness, while it provides various modes of the method depending on the requirements. Also the method can be used for the specific occasion of Visual Cryptography Ciphers’ Steganography.
