This watermarking algorithm features: 1) Adaptive audio segment partitioning and intelligent watermark strength adjustment based on audio characteristics, enhancing robustness; 2) Simultaneous copyright protection and content authentication with approximate tamper localization; 3) Simulation experiments demonstrate excellent imperceptibility and robustness against common processing operations; 4) Capable of detecting replacement attacks and identifying tampered positions. The algorithm implements dynamic segmentation through audio feature analysis and employs psychoacoustic models for adaptive embedding strength calculation.
