摘要

PROBLEM TO BE SOLVED: To provide an authenticity determination system and the like which are capable of determining authenticity of an object.SOLUTION: Information terminals 2-1 to 2-3 read electronic watermark codes 6-1 to 6-3, photographed by cameras 7-1 to 7-3, by prescribed reading software and transmit read code information, as read log data, to a log management server 3 via a network 4. The log management server 3 stores the read log data transmitted from the information terminals 2-1 to 2-3, into a database. The log management server 3 analyzes the read log data stored in the database and creates a warning list to which codes determined to be improbable in original shipping routes and detected in abnormally large quantities as the result of the analysis are added. The log management server 3 delivers the warning list to the information terminals 2-1 to 2-3 via the network 4.
