An information processing apparatus generates authentication data that can be used for authentication of a first object that is included in a captured image captured by a first image capturing apparatus and has been authenticated by a first authentication apparatus corresponding to the first image capturing apparatus; and causes the authentication data to be reflected to an authentication database (DB) of at least one authentication apparatus included in a plurality of authentication apparatuses. The apparatus generates second authentication data corresponding to a second capturing condition differing from a first capturing condition corresponding to first authentication data that is included in the authentication DB of the first authentication apparatus and was used when authenticating the first object.
