An Efficient Steganography Algorithm Based on Visual Cryptography and Least Significant Bit Embedding

Steganography is the process of concealing data within another data. The data may be in any form such as file, image, audio or video. The data to be concealed into another data is called secret data. The original data is called as cover data that hides the secret data. In this paper, an efficient steganography technique is presented which combine the visual cryptography with Least Significant Bit (LSB) embedding approach. The secret data is divided into two data called as shares by random grid techniques. The LSB process inserts one of the shares into the cover image. The remaining share is used by the receiver to recover the secret data. MATLAB is used to implement the proposed system, and the results show the effectiveness of the proposed system.
