1. A system for logging and managing measurement data, the system comprising:
a measurement data management system; and
a data recording apparatus comprising:
a first computer system comprising one or more processors and one or more non-transitory, computer-readable storage media communicating with the one or more processors of the first computer system and storing a first program, wherein:
when the first program is executed by the one or more processors of the first computer system, the first computer system is configured to exchange a first encryption key with the measurement data management system in response to authentication by the measurement data management system;
when the first program is executed by the one or more processors of the first computer system, the first computer system is configured to collect measurement data obtained by measuring a physical quantity associated with a product having a product value, which is impacted by deviation of the physical quantity from a predetermined condition, wherein the physical quantity relates to an external or internal condition of the product;
when the first program is executed by the one or more processors of the first computer system, the first computer system is configured to record the measurement data; and
when the first program is executed by the one or more processors of the first computer system, the first computer system is configured to transmit the measurement data encrypted using the first encryption key to the measurement data management system, wherein
the measurement data management system comprises:
a second computer system comprising one or more processors and one or more non-transitory, computer-readable storage media communicating with the one or more processors of the second computer system and storing a second program, wherein:
when the second program is executed by the one or more processors of the second computer system, the second computer system is configured to exchange the first encryption key with the data recording apparatus in response to authentication of the data recording apparatus;
when the second program is executed by the one or more processors of the second computer system, the second computer system is configured to obtain, from the data recording apparatus, the measurement data, which are encrypted by the data recording apparatus using the first encryption key;
when the second program is executed by the one or more processors of the second computer system, the second computer system is configured to receive a query for requesting an indicator of an added value to be added to the product value; and
when the second program is executed by the one or more processors of the second computer system, the second computer system is configured to transmit, in response to the query, a response including the indicator of the added value calculated by the one or more processors based at least in part on the deviation of the physical quantity from the predetermined condition determined using the measurement data.
