Owner authentication system

An owner authentication system comprising:

• a facility device;
• a data management server connected to the facility device;
• and
• a user terminal connectable to the facility device and the data management server, wherein
• the facility device includes:
• device identification information retention circuitry to retain device identification information that is identification information on the facility device;
• operation data retention circuitry to retain operation data that is dynamic data varying over time in the facility device;
• first information provision circuitry to transmit, to the data management server, device association data in which first operation data in the operation data is associated with the device identification information;
• and
• second information provision circuitry to transmit, to the user terminal, second operation data in the operation data,
• the user terminal includes:
• user identification information retention circuitry to retain user identification information that is identification information on the user terminal;
• and
• authentication request circuitry to request the data management server to perform authentication of whether the user terminal is a terminal corresponding to an owner of the facility device, by transmitting, to the data management server, user association data in which the second operation data is associated with the user identification information, and
• the data management server includes
• matching verification circuitry to perform the authentication by comparing the first operation data included in the device association data with the second operation data included in the user association data, wherein
• the first operation data and the second operation data each include a start date and time that is a date and time at which the facility device started operating, and
• the matching verification circuitry determines that the user terminal is the terminal corresponding to the owner of the facility device when the start date and time included in the first operation data matches the start date and time included in the second operation data.
