Lenovo’s New Patent Shows Its Interest in Using Blockchain For Validating Docs

Blockchain faces more adoption from the world tech giants. Recently, the Chinese multinational tech company Lenovo submitted an application to the U.S. Patent & Trademark Office for a gadget. This device is expected to provide the inviolability of a signed physical doc with the help of blockchain.

Another Blockchain Adoption

A week ago the American agency, which issues patents to inventors, released an application №20180046889, filed by Lenovo Pte. Ltd. of Singapore one year and a half ago, which shows that the tech company aims at using blockchain for physical validation documents.

Why should they use blockchain in this way?

It is not a secret that blockchain tech trend can be used not only in the realm of cyber assets. It is widely adopted in medicine, administrative fields and so on.

In the application by Lenovo, it is stated that entrepreneurs and businesses have not yet broadly endorsed digital or virtual signatures. The reason for this lies in the lack of publicly recognized standards and technological difficulties.


This is a problem as long as a paper doc, which has been signed by human’s solid ink signature and later scanned or sent to anybody by fax or via email, has no protection against any further interference with the help of tech tools. The text after scanning can easily be altered, and this can lead to fraud cases and considerable misunderstandings.

Unfortunately, no digital signature technologies can guarantee the protection of a document either.

On the other hand, the use of blockchain can change this situation for better.

How Will it Work?

According to the filing, the electronic gadget comprises an imager that generates a virtual image of a doc. The apparatus also includes such details as:

  • processor
  • memory
  • document integrity module
  • input device with an imager
  • output device with a printer

The offered device can be embodied either in hard-, software or both simultaneously.
