摘要:
There is provided an electronic watermark generating apparatus including an appliance characterizing information generating unit that generates appliance characterizing information that characterizes an electronic appliance, by using physical data acquired by a sensor that measures characteristics of the electronic appliance, an electronic watermark generating unit that generates, in relation to the appliance characterizing information, electronic watermark information that is used for detecting whether information has been tampered with or not, an embedded position deciding unit that analyzes the appliance characterizing information, and decides an embedded position for the electronic watermark information in the appliance characterizing information, and an electronic watermark embedding unit that embeds the electronic watermark information generated by the electronic watermark generating unit in a position on the appliance characterizing information decided by the embedded position deciding unit.
