This is a blind image watermarking and steganography tool designed to embed and extract hidden data from images without requiring the original source file. It functions as a framework for concealing text or bit arrays within images using mathematical transforms to ensure the marks remain invisible to the viewer.
The system is designed for robust watermark extraction, allowing hidden information to be recovered even after images have undergone rotations, cropping, resizing, noise injection, or brightness changes. It utilizes a blind extraction mechanism that retrieves data using a shared password and the original data shape.
The tool supports digital image copyright protection and batch image processing. It incorporates a parallel image processor that distributes embedding and extraction tasks across multiple CPU cores to increase throughput.
