Method and system for providing restricted access to a storage medium

摘要

A system, apparatus, method, or computer program product of restricting file access is disclosed wherein a set of file write access commands are determined from data stored within a storage medium. The set of file write access commands are for the entire storage medium. Any matching file write access command provided to the file system for that storage medium results in an error message. Other file write access commands are, however, passed onto a device driver for the storage medium and are implemented. In this way commands such as file delete and file overwrite can be disabled for an entire storage medium.

1. A method for applying an operation access privilege to a storage medium, comprises:
associating an operation access privilege with at least a portion of the storage medium; intercepting by at least one trap layer an attempted operation on said at least a portion of the storage medium,
wherein said intercepting occurs regardless of an identity of a user attempting the attempted operation; comparing the attempted operation to the operation access privilege; and allowing, or denying the attempted operation based on the comparing the attempted operation to the operation access privilege.
