Xerox Wins Patent for Blockchain System That Tracks Revisions to Electronic Documents

Xerox was awarded by the U.S. Patent and Trademark Office(USPTO) for a patent on a blockchain-based auditing system for electronic files, as per the patent filing issuedNov. 13.

Xerox — recognized for its eponymous printing and digital copying appliances — first filed the patent in August 2017. The patent explains a blockchain-related system for the secure recording of revisions made to electronic documents.

The technology provided by Xerox can allegedly detect whether a file has been altered and detects the history of changes made. Owing to the decentralized verification mechanism, the system thus becomes resistant to tampering, the filing mentions.

Describing the technology behind the patent, Xerox explains a series of blockchain nodes that may approve or dismiss each amendment made. The filing also suggests that the management network will alert its users whenever a particular node fails to approve the document or the content differs from its certified version.

Xerox considers that the newly patented technology can be used to audit electronic files in many areas, such as medical and financial records, tax papers, and educational documents. The filing precisely mentions criminal investigation records, such as interview notes, crime scene photos and DNA test results that must be endangered from alterations and tampering. 

In 2016, Xerox registered a similar patent, targeting to build a blockchain-related timestamp protocol for data such as copies or pictures. As per the filing, the company wanted themarks to be irrevocable, implying that data bearing such a mark could besubmitted in court asevidence.

Major tech and electronics companies have registered a slew of patent applications for various proprietary iterations and applications of blockchain technology. A September report mentioned that IBM had filed more blockchain-based patent applications than any other company at the time of publication.

IBM has registered over 90 blockchain patents, the most recent of which targets to practice blockchain technology to help scientific research and offer a record of its results.
