UOC's Audio Watermarking System, High-fidelity recovery under extreme conditions

An audio watermark is a sequence of bits embedded in a streamed audio signal (TV, radio or internet). They are imperceptible to the human senses and are only detected by devices such as smartphones or tablets. A watermark contains unique identifiers of both the portion of the audio from which the mark was extracted and the distribution source to which the content can be credited. UOC's system comes up with two innovative aspects: first, the use of the Fourier domain, and second, the use of the time and frequency domains during the embedding. It's an invention by David Megías, principal investigator in the K-riptography and Information Security for Open Networks (KISON), UOC's research group: http://bit.ly/2G5nON7.
