Abstract
A management system that manages contents associated with a hash value registered in a blockchain. A controller of the management system receives contents as a target of authenticity determination and an identification number for identifying authentic contents used as a reference for determining the authenticity of the target contents. The controller determines the authenticity of the contents as the target of the authenticity determination by comparing a hash value generated from the contents as the target of the authenticity determination and a hash value, registered in the blockchain, of authentic contents indicated by the received identification number, and notifies a result of the authenticity determination. In a case where it is determined that the contents as the target of the authenticity determination are not authentic, the controller notifies information on the authentic contents associated with the identification number.
