First Claim
1. A computer-readable recording medium that stores therein a device driver program to control access thereto, the device driver program causing a computer to execute:
- receiving a request for access to the computer-readable recording medium from a process;
determining, in response to received access request, whether to allow access to the computer-readable recording medium based on information about the process; and
allowing the process to access the computer-readable recording medium upon it is determined at the determining to allow access to the computer-readable recording medium.

Abstract
A device driver includes an access permitted directory storage unit and an access-permission determining unit. The access-permitted directory storage unit stores as an access-permitted directory an activation directory for a process that is allowed to access an S memory (private memory). The access-permission determining unit checks whether an activation directory for a process that has requested for access to the S memory matches the access-permitted directory. Based on the result, the access-permission determining unit determines whether to accept the access request.
