TARDOS algorithm

The Tardos algorithm is a method used in digital rights management to detect counterfeiters of digital content like movies or music. It assigns each user a unique, slightly different version of the content, with subtle markings. When a pirated copy appears, the algorithm analyzes these markings to identify which user(s) may have leaked it. It’s designed to efficiently detect and trace multiple guilty parties, even if they try to hide their copies or collude. Overall, it’s a robust approach to protect owners’ rights by pinpointing dishonest users through clever encoding and analysis techniques.
