  • Abstract

    A robust watermarking system for strengthening audio against unauthorized access and tampering is proposed in this paper. The system can ensure robustness and imperceptibility by embedding watermarks to random time instants in the frequency domain with the help of ‎FFT and encrypting the metadata by AES encryption. Thorough evaluations based on SNR, MOS, and extraction accuracy confirm ro-‎robustness of the system against common attacks such as noise, compression, and resampling. The novel system is applicable in the field of ‎digital rights management by offering a trustworthy and efficient solution for audio authentication and copyright protection‎.
