INPUT/OUTPUT CONTROL SYSTEM, INPUT/OUTPUT CONTROL METHOD, INPUT/OUTPUT CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide a system which flexibly controls input/output operation to resources by application programs (APs) and prevents abuse of resources and APs except the use intended by users or providers of the resources or APs. SOLUTION: In this system, when a request for input/output operation of a resource 1 is output from AP2 (S1), a platform 3 conducts authentication for AP2 and an AP policy 2a (S2), and conducts authentication for the resource 1 and a resource policy 1a (S3). The platform 3 makes a control policy 3a based on the detected AP policy 2a and the resource policy 1a, and controls an input/output operation (S4) to the resource 1 from AP2 based on the control policy 3a. The use against the intention of the providers or the users of the APs and the resources can be prevented by controlling the input/output operation so that the input/output operation is prohibited when the operation does not meet the control policy 3a.
