A control unit of an information processing apparatus acquires product information of each of one or more inclusion products included in a target product based on association information indicating an association relationship of products of companies included in a supply chain. The product information includes traceability-related information of the at one or more inclusion products. The traceability-related information is encrypted with a public key of a certificate authority. The control unit acquires an encrypted integrated result of the traceability-related information by computing the encrypted traceability-related information through secure computation. The control unit decodes the encrypted integrated result of the traceability-related information through the certificate authority.

A manufacturing method of a fibrous perovskite-type oxide catalyst includes: a first preparing step; a jetting step; a heating step; and an impregnating step. The first preparing step prepares a first solution by mixing metal salts containing La, Sr, Fe, Co and O elements, a first polymer, a metal salt containing a Zn element and a first solvent. The jetting step jets the first solution by using an electrospinning method to produce a precursor fiber. The heating step heats the precursor fiber to produce a perovskite-type oxide mixed with a Zn oxide. The impregnating step impregnates the perovskite-type oxide with an alkaline solution to remove the Zn oxide.
