Xerox proved Copier giants to explore the block chain timestamp strategy


nnnLast week, the US Patent and Trademark Office (USPTO) published a new patent submitted by Xerox, which outlined the use of block chains to bind data types to a certain period of time. At the same time, the Proof of Existence project is specifically mentioned in this patent. It is reported that Xerox has already submitted at least two pieces of chain-related patents, all mean to use this technology for record keeping system.n
nnTranslation: Clovern
nA technology company known for its name copiers will seek to use block chains to create digital proofs for documents and other forms of data.n
nJust last week, the US Patent and Trademark Office (USPTO) published a new patent submitted by Xerox, which outlined the use of block chains (public chains or alternative license chains) to link data types (such as pictures and videos) Set to a certain period of time.n
nAfter describing in detail the use of the Bitcoin block chain after the timestamp, the Proof of Existence project is mentioned, which continues to state that:n
nnAccording to a feature of an embodiment of the present invention, an information processing apparatus provided by the present invention includes an acquisition unit that obtains characteristic information of the latest block in the block chain when generating the target data, and a registration unit that serves the time proof service And the authentication information associated with the feature information acquired by the acquisition unit when the target data is generated.n
nnInterestingly, the application was the same as another patent application filed by Xerox in 2015, but the text of the previous patent application did not mention the block chain.n
nAs CoinDesk previously reported, Xerox has already submitted at least two pieces of chain-related patents, both of which suggest the use of the technology as a record-keeping system.n
