CONTROL METHOD, CONTROL PROGRAM, AND INFORMATION PROCESSING DEVICE

To improve authentication accuracy. A processing unit (12) receives a plurality of pieces of captured data of a person, and generates weight information indicating a weight applied to each of the plurality of pieces of captured data on the basis of quality of each of the plurality of pieces of captured data and the number of the plurality of pieces of captured data. When representative data representing the plurality of pieces of captured data is calculated from the plurality of pieces of captured data, the processing unit (12) applies an algorithm in which the smaller the weight indicated by the generated weight information, the smaller an influence of each of the plurality of pieces of captured data on a calculation result of the representative data.
