Proof for Origin and Ownership by Watermarking

Document Thumbnail

The presented paper examines the general concept behind watermarking set against the requirements of audio forensics and comes to a conclusion that watermarking - being a convenient way to mark and track recordings - can be turned into an effective tool in the hands of investigation only when the detection channel is secured. It is not enough to have an embedding and detection algorithm on their own: the input and output processes must be backed up by an individual identifier allowing or prohibiting access to the data hosted within the audio.
