Verizon obtains patent for virtual SIM cards based on blockchain

The leading communications and technology company, Verizon, has obtained a patent for the use of virtual subscriber identity modules (vSIMs) for customer devices.

On September 10, an application was filed with the United States Patent and Trademark Office detailing a blockchain encryption technology, in which a traditional physical SIM card can be replaced by a software version SIM According to the file, this guarantees more security and the existence of a single copy of the vSIM on one device at a time. The document explains in more detail:

"The network device starts the creation of a blockchain that includes a vSIM certificate for network services, in which the vSIM certificate includes an international mobile subscriber identity (IMSI). [...] The vSIM can be retrieved and used by any of the different devices associated with the user account, transferred between devices associated with the same user account, or temporarily assigned to other users. "


Protection with an authentication code

VSIMs are protected with a special authentication code that prevents any party from accessing it if the authentication code received from a client device does not match the authentication code registered on the vSIM platform.


Attempts to bribe Verizon staff for information on the SIM card

In a dedicated analysis published in November last year, Cointelegraph reported that an anonymous source on Verizon had been contacted through Reddit, where bribes were offered in exchange for SIM exchanges. He was told that he could earn up to USD 1,000 per week by transferring customer phone numbers to the new SIM cards.

Another Verizon employee said the hacker, who also found him in Reddit, promised he would earn "USD 100,000 in a few months" if he cooperated - all he had to do was "or activate the SIM cards for [the hacker] when [he was ] at work or give the attacker his] Employee ID and PIN ".


Blockchain priorities

This summer, Verizon actively sought to hire new recruits for work related to blockchains, including blockchain developers. In particular, Verizon published five vacancies for a blockchain developer on July 1. According to the list, successful applicants would have to "research, design, develop and test blockchain technologies," among other responsibilities.
