Will Lenovo be the next company to use a Blockchain application? As a recent patent suggests, it looks quite the same. In the now publicized letter, there are indications of an implementation of blockchain features in the validation of documents.
Last week, the US Patent and Trademark Office (USPTO), the United States Patent Office, issued a document stating that Lenovo might be working on the implementation of blockchain plans in the near future. Specifically, the patent aims to verify the authenticity and validity of documents and protocols using a blockchain-like mechanism.
Thus, the Chinese technology corporation describes in the form a mechanism in which a digital signature is encoded in a document. By using such a coding instead of a physically printed tag, the recipient can be sure that the document has not been altered after being created. A computer should later decode the signature and make it comparable to a physical document.
This technology should build a bridge between the digital and the analog world. Through the presented and now patented mechanism, it should be possible in the future to cryptographically encrypt even physical and non-digitized documents. This is to prevent physically printed documents from being manipulated after being signed.
"If a paper document is physically signed with an ink stick and then scanned, faxed or emailed, there is no guarantee that the text of the document has not been substantially altered after the signature. A wide range of digital signature technologies exist today, but they do not provide tamper-proof mechanisms for checking physical documents printed with physical ink, "
it says in the patent of Lenovo.
