invisible watermarking
Invisible watermarking is a technique used to embed digital information into an image or document in such a way that it is not visible to the naked eye. This hidden information can be used for various purposes such as copyright protection, authentication, and tracking. The process involves altering the pixels of the image slightly to encode the information without degrading the quality of the original content. Invisible watermarking provides a way to prove ownership or authenticity of digital media without altering its appearance.
