Copy Detection Mechanisms for Digital Documents

Summary: Registration-based copy detection for digital documents; COPS detects complete or partial copies in a digital library. Algorithms, evaluation metrics (accuracy, efficiency, security), and prototype results inform scalable deployment and parameter tuning for robust copyright protection.
