Software authentication system, software authencation program, and software authentication method

摘要

A software authentication system authenticates software including a function module on the basis of log information created by a resource management system. The resource management system includes a resource measuring unit; a resource exchanging unit; a resource restriction information acquiring unit; a log information creating unit that creates the log information indicating that the amount of resources used by the function module has reached an upper limit value. In addition, the software authentication system includes a log information acquiring unit that acquires the log information; an operation determining unit that determines whether the amount of resources used by the function module does not reach an upper limit value on the basis of the log information acquired by the log information acquiring unit; and a software authenticating unit that adds authentication information to the software when it is determined by the operation determining unit that the amount of resources used by the function module does not reach the upper limit value.
