Faronics Assigned Patent

Faronics Corporation, Vancouver, Canada, has been assigned a patent (9,152,824) developed by Lomnes, Randy Keith, Pender Island, Canada, for a “method and system for automatically preserving persistent storage.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Computer-based methods, techniques, and systems for automatically protecting a storage device from unwanted alterations are provided. Example embodiments provide a Disk Access Redirection System, which includes a Redirection Driver, an Available Space Table, (‘AST’), a Protected Space Redirection Table, (‘PSRT’), and optionally an Unprotected Space Table, (‘UST’). The Redirection Driver is installed and registered with the computer operating system so that it can intercept storage device access requests, such as a disk read/write). When a storage access request for a read or write is sent, the request is intercepted by the Redirection Driver, transparent to the code that invokes the storage access request. The Redirection Driver uses the AST, PSRT, and optionally the UST, to allocate available storage space for redirected write requests, redirect write requests for protected areas of the storage device, and redirect read requests when the read request specifies a storage location that has been previously redirected.“

The patent application was filed on February 18, 2011 (13/030,872).
