Lenovo is supposed to launch a new advanced product on the market. The company will use blockchain as part of a system for verifying the validity of physical documents.
According to the application released by the U.S. Patent and Trademark Office (USPTO), the company describes a set-up that utilizes digital signatures encoded in physical documents, which can be processed by computers to verify the legitimacy of a document. It is indicated a new product that operates with digital signatures codes and security blockchain. It will allow connecting the device to any computer or machine.
Using the security blockchain, anyone can validate that they have the current authentic physical document even if multiple paper copies exist and multiple people have made entries in the chain of modification. If any forgeries exist, they will show up as orphaned blocks in the chain. To validate a paper copy, a user of the electronic device takes a picture of the printed code on the physical document.
The company claims that all persons involved in having copies of a document have no negative consequences in terms of the information alteration.
However, this is not a first company’s experiment with blockchain technology. Last year, IBM had started working with the company on a blockchain-based invoicing system. They have worked on a project related to billing and transparent processing operations.
