Blind Watermark is a Python library for embedding hidden information inside images and recovering it without the original source image. It uses a DWT-DCT-SVD signal-processing pipeline to place watermarks with minimal visible change. Watermarks can contain text or raw bit arrays and may be protected with separate image and watermark passwords. The package provides both a Python API and command-line interface for embedding and extraction. Its examples evaluate recovery after rotation, cropping, masking, resizing, noise, cuts, and brightness changes. Multiprocessing can use several CPU cores during processing. The project is intended for copyright marking, traceability, and image steganography experiments.
