Provided is an information processing utilization management system (IPUMS) that can determine whether an information processing device (IPD) is available from an application of a mobile terminal (MT). The IMPUMS includes the MT and IPD connected thereto via a network, the IPD accepting a process request (PR) from the MT-installed application to execute a process. The MT includes a process data (PD) generation part generating PD based on the PR from the application to transmit the PD to the IPD. The IPD includes a PD receiving part receiving the PD, a MT kind-code obtaining part obtaining a kind-code of the MT from the PD, an application information (AI) obtaining part obtaining II of the application from the PD, and a utilization restriction determination part determining whether the PR from the AI is acceptable based on the kind-code of the MT and the II of the application.
