Abstract:
An image coding device adapted to code time-continuous pictures is provided. An embedding position information conversion unit acquires embedding position information indicating a position in a picture, by using a one-way function based on time-continuous information. An image coding unit selects a coding block in the picture based on the embedding position information, embeds electronic watermark information in a coding parameter used to code the coding block, and codes the coding block by using the coding parameter in which the electronic watermark information is embedded.
