A settlement processing device, which is an example of an information processing device, includes an acquisition unit, a verification unit, and a providing unit. The acquisition unit acquires, from a user terminal used by a user who is a request source for a service, proof information that is for proving, by zero knowledge proof, that a user is an identity verified user, and that is generated by using secret information that only the identity verified user is allowed to know. A verification unit executes a verification process of proof information acquired by an acquisition unit by using encrypted information of identity verification information used in an identity verification process of the identity verified user managed in a block chain system, where the encrypted information is encrypted using secret information. The providing unit executes a process for providing a service to a user who is a request source for a service on condition that the user is proved to be an identity verified user as a result of the verification process by the verification unit.
