Blockchain Technology to be explored by Lenovo with U.S Patent for Document Validation

Lenovo has registered a patent with USPTO (U.S Patent and Trademark Office) for a system to verify the sincerity of physical documents by using a security Blockchain.

The patent application was submitted in August 2016 but was published late last week on Feb. 15.

The use of digital signatures encoded into documents, opposing to physical signatures printed with physical ink provide support that the document cannot be changed after the signing.

The patent’s “Brief Summary” reveals that a processor will identify an “integrity symbol” within the document, convert it into an “integrity map,” and then compare the map to the physical document to ensure the document’s integrity.

Lenovo described:

“We have the current authentic physical document even if multiple paper copies exist and multiple people have made entries in the chain of modification.  If multiple, fake copies of a physical document came into existence, they would show up as orphaned blocks in the chain.”

Anyhow, Lenovo’s patent wasn’t presented recently, while China cracked down the usage of ICOs and cryptocurrencies in the country. China banned all foreign cryptocurrency exchanges in early February, following a September 2017 ban on Initial Coin Offerings (ICO).

Swiss Financial Market Supervisory Authority Published Guidelines for ICO Organizers. Following Switzerland, Spain also announced that it is going to Legalize Cryptocurrency after Swiss Recently Rolled out Guidelines for ICOs.
