Abstract

Unused storage space within a data storage is utilized to store data while effectively making it appear to the operating system, other programs, and the user that the space is still available or unused. The space used to store the hidden data remains available for use by the operating system, other programs and uses upon a request. File system requests are monitored such that the hidden storage area remains hidden from unauthorized processes as well as to restrict operations within the hidden storage area that are attempted by unauthorized processes.
