When use of an information asset in the unavailable state is requested by an application corresponding to the use permission range, the information asset is decrypted to cause the information asset to be in the available state. When the use of the information asset in the available state by the application ends, the information asset is encrypted to cause the information asset to be in the unavailable state.
