1. An image processing apparatus comprising:
a memory storing captured image data; and
an electronic processor configured to:
determine a characteristic of the captured image data,
select, based on the characteristic of captured image data, metadata relating to authenticity verification, of metadata including information of a plurality of items being associated with the captured image data,
calculate a hash value as to the captured image data and metadata being associated with the captured image data,
generate signature data based on the hash value that is calculated,
set marking information in the selected metadata relating to the authenticity verification, and
integrate the signature data, the captured image data, and the metadata in which the marking information is set to render the integrated signature data, captured image data, and metadata capable of being recorded.
