Abstract
A user device includes: a holding unit that holds confidential information; a generation unit that generates a generator; an arithmetic unit that calculates a commitment corresponding to the generator, on the basis of the generator and the confidential information; and an acquisition unit that transmits, to a first external device, an acquisition request including the generator and the commitment corresponding to the generator, to acquire a verifiable claim (VC) including the generator and the commitment corresponding to the generator. In the user device, the value of the generator the acquisition unit uses to newly acquire the VC is different from the value of the generator the acquisition unit has used to acquire the VC in the past.
