Robust Watermarking

Robust watermarking is a technique used to embed a hidden signature or mark into digital content like images, videos, or audio. Its goal is to make this mark resistant to common alterations such as compression, resizing, or noise, ensuring it remains detectable even after the content has been edited or attacked. This helps verify ownership or authenticity, protect intellectual property, and prevent unauthorized use. Essentially, robust watermarking balances invisibility (so it doesn’t bother viewers) with durability, maintaining the embedded information despite attempts to modify or obscure the content.
