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.

Abstract: A management system that manages content data corresponding to a hash value registered in a block of a blockchain. Content data selected by a user from among pieces of content data that are management targets, is provided to a provision destination of the selected content data. Information on the provision destination of the selected content data is registered in a block of the blockchain in association with an identification number for identifying the selected content data. When the management system receives content data that is a target of authenticity determination, an identification number for identifying the content data, and user information of the content data, authenticity of the received content data is determined. In the determination of the authenticity of the received content data, the received user information is compared with the provision destination information registered in the blockchain.
