PROBLEM TO BE SOLVED: To provide a license management system which is applicable even to a stand-alone computer, and can easily perform a processing related with the displacement of software. SOLUTION: In the license management system 1, a PC 2 makes an IC card 3 authenticate an authentication code stored at the PC 2 side in starting software 5. The IC card 3 authenticates an authentication code by using a reference seed making a pair with the seed of the authentication code, and when the authentication succeeds, the IC card 3 increments a reference counter included in a reference seed. When the IC card 3 succeeds in the authentication of the authentication code, the PC 2 permits the start of the software 5, and increments the authentication counter included in the seed, and makes the IC card 3 generate the authentication code on the basis of the seed, and stores the authentication code generated by the IC card 3 as the authentication code to be used for the next start management.
