Abstract
A reference-color-list generating unit of a server generates a reference color list on the basis of reference color lists stored in a CLDB, at a timing reported from a program-information management unit. An S-metadata generating unit generates S metadata from TV program information stored in an RVDB and the reference color list. A C-metadata generating unit of a user terminal generates C metadata from individual information of each frame constituting a captured image and the reference color list. An authenticity determining unit determines whether to permit or deny check-in by a user on the basis of the obtained C metadata, the S metadata extracted by the CMDB, and program detail information managed by the program-information management unit.
