FIELD: information technology.
SUBSTANCE: there is provided a receiving device including a content receiving unit configured to receive content; a digital watermark information receiving unit configured to acquire information establishing a content leakage route to form a digital watermark; and a content output module configured to embed the digital watermark in the received content using the information received and made to output the content. The information for generating a digital watermark includes at least source information identifying the source of content transmission and device information identifying the receiving device. The source of transmission is external in relation to the receiving device, so that the source of transmission does not coincide with the receiving device, and the embedded digital sign identifies the source of transmission and the receiving device providing the indication of the leakage route.
EFFECT: setting the content leakage route.
