LSB Watermarking Image Algorithm with Attack Testing Code

Implementation of Least Significant Bit (LSB) watermarking image algorithm including attack simulation code for robustness evaluation.

Digital Watermark Information Hiding Using LSB (Least Significant Bit) in Carrier Images

Digital watermark information is concealed in the LSB of carrier images through direct replacement. This method is straightforward to implement but exhibits poor robustness, making it vulnerable to attacks such as noise addition, filtering, and cropping. Code implementation typically involves pixel-wise bit manipulation for embedding and extraction.

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.
