text_blind_watermark

Text Blind Watermark is a Python package for hiding an invisible message inside ordinary plain text. It modifies the underlying character sequence without creating an obvious visual difference for readers. A password controls how the watermark is embedded and later extracted. The API can process text loaded from files and return a protected version for saving or sharing. The project has been tested across macOS, Windows, Linux, browsers, and several messaging or publishing platforms. An online demonstration and a Rust-related implementation provide additional ways to explore the technique. It is useful for ownership marking, leak tracing, and experiments with text steganography.
