The present invention is a computer system in which computer environments (0101 and 0102) can dispatch replicas (0111 and 0112) of a software asset possessed by a user to a counterpart side, and at a counterpart-side computer environment (0100), the software asset can be executed; wherein authentication of software asset usage rights for restricting usage in other than predefined conditions is achieved using an authentication query verification unit (0105) and an authentication query generation unit (0113). An authentication key is generated on the basis of combination information of software assets that may not be used at the same time at the user side and the counterpart side, which have been generated by replication of the software asset, and operation information of software executed at the counterpart side, and by exchanging the authentication key between the counterpart side and the user side, validity of usage of the software assets is verified. |
