Abstract
A digital media with encoded audio-visual content includes an encoded token. The token comprises visual data having defined characteristics, which are designed such that when the audio-visual content is output as analog output and then re-recorded as digital data, the resulting digital data includes an altered token. Digital data may be processed to detect altered tokens indicating that the data was recorded from an analog output. When an altered token is detected, the copy may be considered to be an unauthorized copy and handled accordingly.
