A flag converting part (12) converts a form of a share of a flag representing a last element of a group. A flag applying part (13) generates a share of a vector in which a value of a value attribute is set if a flag representing the last element of the group is true, and a predetermined value is set if the flag is false. A sorting part (14) generates a share of a sorted vector obtained by sorting the vector with a permutation which moves elements so that the last elements of each group are sequentially arranged from beginning. An output part (15) generates and outputs a share of a vector representing a maximum of each group from the sorted vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure aggregate maximum system, secure aggregate minimum system, secure computation apparatus, secure aggregate maximum method, secure aggregate minimum method, and program","description":"An aggregate maximum is efficiently obtained while keeping confidentiality.
