A user information utilization system includes: a user information storage means that stores user information; a temporary ID acquisition means that acquires a temporary ID for identifying the identicalness of a user between a plurality of devices or a plurality of service providers, the temporary ID being an identifier corresponding to a user of the stored user information; a user information comparing/determining means that compares legitimately-read user information of a plurality of users read in response to acquired two or more temporary IDs and a user information comparison/determination request that designates a predetermined condition that represents a desired relationship between a plurality of users represented by the two or more temporary IDs to thereby determine whether the relationship between the designated users satisfies the predetermined condition, and outputs the determination result; and a process execution means that receives the comparison/determination result for the user information and executes a predetermined process based on the received comparison/determination result.
