An improved LSB based Steganography with enhanced Security and Embedding/Extraction
Parvinder S. Sandhu · 2013
The proposed system is an approach used to embed text into gray image (BMP).It enables the user to provide the system with both text and cover, and obtain a resulting image that contains the hidden text inside. The system uses the least significant Bit (LSB) method to embed the secret text in image after encrypt the secret text using RC4 stream cipher method and store the text in non sequential pixel in image by using variable hope value power of 2(2, 4, 8, 16, 32).The Proposed system aim to provide improved robustness, security due to multi-level security architecture along with faster embedding and extraction process irrespective of size of embedded text.
