Image-Based Information Concealment Using Encryption and Decryption Algorithms
Steganography involves embedding information within images while utilizing encryption and decryption algorithms to ensure data security during the concealment process.
Steganography Tools for Text Concealment in True Color Images
Steganography tools implementing LSB (Least Significant Bit) techniques to embed text files within true color images while maintaining visual fidelity through RGB channel manipulation.
Enhanced LSB Algorithm Implementation
A MATLAB implementation of an improved Least Significant Bit (LSB) algorithm featuring both data hiding and extraction functionalities. The implementation uses the standard Lena test image as a sample carrier, successfully embeds secret information, and accurately retrieves the hidden data through the extraction algorithm. Code includes pixel manipulation techniques and bit-plane operations.
