In the introduction to the patent application, the USPS states that as people's daily interactions move to online activities, the tools that give users confidence do not provide an adequate level of security.
Among the components of the infrastructure is a module for registration and registration of the user, with a verification component; a module that provides public and private key users with an email module, a data access component and the blockchain module, which serves as a distributed database for the storage of information.
Also mentioned in the application is a "special digital token" that could be used as part of a provisioning phase to interact with the secure digital infrastructure. There are no additional details about the token nor about the specific operation of the blockchains, beyond specifying that a blockchain will contain the information of the users and that there is an unspecified number of blockchains, apparently destined to the operation of different services.
It is inferred that with this patent application, the USPS wants to use the proven benefits of the blockchain in transparency, immutability of its records and lower transaction costs, in order to continue offering security and confidence to its users.
