Abstract
A system and method for restricting the use of secure data on a computer system are provided. An interception program may be added as part of an interface program. The interception program may control access to the content of storage media such as an extension to the file system program of the operating system of the computer system. The secured data may be encrypted, and requested data may be decrypted by the interception program before it is returned. If the intercepted file system access operation is to open the secured data, but does not originate from an application program including executable program code stored within the secured data, the file system access operation may fail. In addition, an error message may be displayed implying that the user does not have sufficient privilege to access the requested data.
