Proof of Xerox? Copier Giant Pursues Blockchain Time-Stamping Strategy
Xerox may be looking to use blockchain to create digital proofs for documents and other forms of data, according to a patent filing.
A technology company best known for its eponymous copier machines may be looking to use blockchain to create digital proofs for documents and other forms of data.
Just last week, the U.S. Patent and Trademark Office (USPTO) published a new patent filed by Xerox in which it outlines a method by which a blockchain (either a public option or a permissioned alternative) could be used to tie types of data (naming images and video as examples) to a certain period in time.
After detailing the use of the bitcoin blockchain for time-stamping purposes – mentioning the Proof of Existence project by name, the application goes on to state:
Interestingly, the filing shares a name with another Xerox patent application submitted in 2015, though the text of that application makes no reference to blockchain.
As previously reported by CoinDesk, Xerox has already submitted at least two other blockchain-related patents, both of which hinted at the use of the tech for a record-keeping system.
