Telecommunications conglomerate Verizon is eyeing using blockchain know-how to underpin the dynamic creation of digital SIM playing cards.
The firm was granted a patent with the U.S. Patent and Trademark Office for the idea on Sept. 10, during which it units out the way it the invention might get rid of pre-inserted, branded bodily SIM playing cards.
The patent describes how a bodily SIM card might be changed by a software program equal – a digital SIM (vSIM) – that’s secured with blockchain-based encryption.
A tool on the cellular community would create a consumer account for storing a number of vSIMs and a choice of community providers to be related to the account.
The community system then creates a blockchain document together with a vSIM certificates for the community providers and an International Mobile Subscriber Identity (IMSI) – a quantity that uniquely identifies all customers of a cellphone community. The vSIM certificates is then linked to the consumer account and could be activated on a shopper’s cellular gadget.
Participating nodes on the “distributed consensus network” would keep a listing of data that Verizon calls a vSIM blockchain. This can be secured from malicious tampering by storing time-stamped transactions in cryptographically secured blocks. Records on the vSIM blockchain can be saved in a hash tree construction for effectivity and to be sure that blocks are acquired “undamaged and unaltered,” in accordance to the patent.
Notably, the vSIM might be assigned any of a number of cellular units linked to the consumer account and transferred between the units. It may be briefly assigned to different customers, says Verizon.
Backing all of it up can be a vSIM platform hosted by the cellular community supplier that shops a consumer repository of vSIMs utilizing a variety of software programming interfaces (APIs).
According to the patent:
“In one implementation, users can accept new vSIM certificates into a user account, transfer a vSIM among client devices associated with the user account, or deliver a vSIM certificate to another user.”
This would seem to recommend that, say, a firm might buy a variety of vSIMs, assign them to its employees at will and later re-assign them to different staff utilizing the system.
Verizon has previously backed a $15m funding spherical for Filament, a agency working on blockchain hardware for the web of issues.
