Digital Watermarking
Digital Watermarking refers to the process of embedding information into digital content in a way that is difficult to remove. It involves inserting a digital signal or pattern into digital media, which can be detected or extracted later to verify the authenticity and integrity of the content or to trace unauthorized copies. Unlike digital watermarks, digital watermarking often aims to be imperceptible, ensuring that the quality and usability of the original content are not compromised while providing an additional layer of security and copyright protection.
