Patent Issued for Automated Remediation of Corrupted and Tempered Files

June 17, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Symantec Operating Corporation (Mountain View, CA) has been issued patent number 8745001, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventor is Goldschmidt, Cassio B. (West Los Angeles, CA).

This patent was filed on March 31, 2008 and was published online on June 3, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "This invention relates to data storage systems and, more particularly, to performing backups and restores of data in data storage systems.

"Backup systems are used to protect data against loss. Typically, a backup system includes software that periodically copies user data to a backup storage device (e.g., such as a tape drive). If data is lost (e.g., due to user error or device failure), the backed-up copy of the data is retrieved from the backup storage device.

"Many organizations implement a network-based backup system in order to ensure that the organization's data is regularly backed up. By way of non-limiting example, a company can implement a network-based backup system to ensure that employees' data is backed up on a daily basis. Data that is stored on storage devices connected to the network is then backed up at regular intervals.

"Unfortunately, inadequate options exist for detection and remediation of individual files suffering from the impact of tampering or corruption. Modern backup systems are focused on the recovery of disasters that inflict loss of entire volumes of files. When a large amount of data is lost or destroyed (e.g., by the loss of a physical hard drive or destruction of a server resulting from lightning strike), the loss of data is easily identified by the end user. Loss of individual files (e.g., through viral corruption or user tampering) is far more difficult for the user to detect and remedy. Viruses are frequently designed to disguise damage and operate covertly until massive damage to a system has been accomplished. A user tampering with a file may be similarly motivated to reduce visible evidence of tampering. In either case, no thorough and automated system for detecting and remedying damage to individual files exists."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "A method, apparatus and computer-readable storage medium for ascertaining a set of preliminary characteristics of a first data structure and, responsive to determining that the set of preliminary characteristics matches a set of characteristics of a reference data structure, determining that a secondary characteristic of the first data structure indicates a replacement of the first data structure with the reference data structure is disclosed. Embodiments of the present invention further include replacing the first data structure with the reference data structure, in response to determining that the secondary characteristic of the first data structure indicates the replacement of the first data structure."
