Abstract
To perform high-speed and efficient processing of determining a correlation between vectors. An information processing system includes: a first information processing device having k number of vectors including secure data as an element; and a second information processing device having m number of vectors including secure data as an element. The first information processing device receives vector information regarding a vector Y selected from the m number of vectors, as encrypted data, from the second information processing device. A data processing unit of the first information processing device sequentially calculates element-based sample identifiers each having a specific common value for each of a plurality of different vectors Y selected from the m number of vectors to one vector X selected from the k number of vectors retained by the first information processing device, and sequentially determines the correlation between the one vector X and each of the plurality of different vectors.
