ABSTRACT:
This invention allows verifying whether or not an original image content has been altered, to specify all edit processes applied to the original image content, and to hold the edited content. To this end, upon inputting a digital content file to be edited, first verification data included in that file is verified. After the content is edited, edit record information for the content is generated. Upon completion of the edit process and outputting the edited content, second verification data is generated based on the verification result of first verification unit, the edit record, and the edited content. The edited content, the edit record, the verification result of the first verification unit, and the second verification data are combined as an edited digital content file, and the combined file is output.
