WAKE: Watermarking Audio with Key Enrichment

WAKE is the first key-controllable audio watermark framework, which aims to embed watermarks into audio and decode the embedded watermarks using specific keys, as shown in the following Figure. If an incorrect key is used, it will be impossible to decode the correct watermark, substantially enhancing the watermarking system's security and scalability while also fulfilling personalized watermarks. Notably, WAKE can achieve multiple watermark embeddings and corresponding watermark decoding based on the key used during embedding. WAKE outperforms the current state-of-the-art audio watermarking models in watermarked audio quality and decoding performance.
