Backing Up data with Blockchain is the Next Move by US Postal Service
The U.S. Postal Service is looking at blockchain as a part of a system for building up digital trust, recently announced patent document demonstrate.
The “Methods and Systems for Digital Trust Architecture” patent application was announced on 22nd March having been initially registered last September. As per the application, “it is apparent that the devices that provide trust to the users are lacking in their ability to adequately provide a desired level of assurance,” referring to concerns like transaction altering and unsafe messaging, among others.
The application goes ahead to note:
“There are many excellent reasons for online communications to continue as they have been. However, in a multi-party, open source environment, there is also a need for a secure, trusted, and enforceable online environment, to enable greater trust and therefore the expansion of offerings online.”
The system illustrated in the Postal Service’s application incorporates many components, including one devoted to email and another that arrange public and private keys for the clients. It notably likewise calls for a blockchain component that, “may be configured to receive records from the user and add the records to a blockchain.”
As indicated by the application, some of these parts could work in tandem. Including the connecting of the blockchain and email sections.
The application demonstrates:
“In some aspects, the user email component is further configured to receive input indicating whether information indicating the transmission of the encrypted email body data is to be stored in a blockchain and store the information in a blockchain in response to the input.”
The Postal Service’s application also highlights the utilization of a “special digital token,” however it is uncertain this alludes to any scarce form of data that would exist on the previously mentioned blockchain. Per the text, “the token is used to create a record for the user for inclusion in a blockchain.”
It later clarifies:
“The block chaining of a special digital token provides evidence that a specific transaction occurred, and specifically who was involved.”
The filing is a remarkable one, given that in 2016, a report from the Postal Service recommended that the mail carrier could move to make its digital currency as well as use the tech for supply chain applications, among different regions.
