Abstract

The present invention makes it possible to satisfactorily specify an outflow route for content. A content reception unit receives broadcast content or communication content. An electronic watermark information acquisition unit acquires information specifying an outflow route for content in order to create an electronic watermark. A content output unit uses the information for creating an electronic watermark to embed an electronic watermark in the received content and output the content. The electronic watermark is embedded in the output content by using the information specifying the outflow route for that content and it is therefore possible to specify a distribution route if the content is used in an unauthorized manner.
