Appl. No.:

9/114756

Inventors:

Robert Phillip Starek - Austin TX

Assignee:

International Classification:

G06F 1730

US Classification:

707206

Abstract:

A method and apparatus are provided that enhance file system calls to a file system structure of an operating system. In particular, file system calls can be enhanced to provide real-time secure file deletion on an ongoing basis. A file system call that is intended to perform a function with respect to data stored on a storage device is intercepted. It is then determined whether the file system call is of a type that should be processed. If not, the original file system call is passed on through the file system. If the file system call should be processed, supplemental processing is performed to enhance the original file system call and the file system call is transparently returned to the calling system application. In embodiment, real-time secure file deletion is implemented using a vendor supplied driver (VSD) executing within the installable file system (IFS) of WINDOWS 95. Further, a method and system are disclosed for real-time secure data deletion in a system having an NTFS file system.
