“When you use this network, you provide an IMSI number to show the backbone that you are a paid customer and here are the services you have subscribed to,” says Schmitt. “The system then informs others of all the information you need to log in to the network. But what we do with PGPP changes the calculus. The registration process can prove that you are a user without knowing who you are. We have removed the charge and changed the payment and confirmation. ”
Reimbursement of payments and distribution of software to users can be easier for carriers than additional networks. Raghavan and Schmitt are in the process of redesigning their research to make the service easier between US telephones. He acknowledges that while he may be comfortable raising children, it is still too late for all companies to switch to PGPP soon. But obtaining just a few items, he says, can still make a big difference. It is because the amount of space is less than if any part of it was displayed. If 9 million Boost mobile users, for example, are required to publish the same or fixed IMSI numbers, which could affect the accuracy and profitability of both storage.
The fact that young people who do not use their own water machines – known as MVNOs – can use this method surprisingly, is important, says photographer Bruce Schneier, who began studying PGPP in January and recently became a project consultant.
Schneier states: “One carrier can do this on his own without the consent of anyone else and without anyone else changing anything,” he says. “I can imagine one of these small companies claiming to offer this as a supplement, because they want to differentiate themselves. To do low-cost confidentiality at the lowest possible price, then be careful.”
A competitive, wireless monolithic market, privacy differentiation can be as exciting as an advertising strategy. It is possible that the three senior carriers may try to prevent MVNOs from engaging in other activities such as PGPP through a legal agreement. But researchers say some MVNOs have shown interest in the request.
Between being forced out of legal compulsions and losing access to data — including the need to share programs or drive calls to participate — carriers may have little incentive to use PGPP. Until the security forces can oppose the plan, Schmitt feels that it is still possible for carriers to make records of locations that have been completed on certain phone numbers. And the researchers say they believe the method could be legalized in the US under the Communications Assistance for Law Enforcement Act. This is because one of the warnings of PGPP is that it only adds privacy to cell-based connections that affect data such as 4G or 5G. It does not attempt to associate with the popular technology that guides mobile phones and SMS messages. Users need to rely on VoIP calls and instant messaging over private information.
The system also monitors IMSI numbers, along with its 5G counterparts known as the Subscription Permanent Identifier, or SUPI, and does not protect or stock up on sensitive devices such as International Mobile Equipment Identity (IMEI) or media control (MAC) addresses. This does not apply to interactions with cells that researchers are trying to avoid, but may offer alternative diagnostic options.
Having a simple and straightforward approach to dealing with local knowledge is essential, however, after many years of misusing data and meeting privacy challenges.
“Simply put, the way I feel now is that we haven’t seen this before?” Raghavan says. “It’s not, ‘wow, this was hard to recognize.’ It is obvious when we remember. ”
“This made us feel good as researchers,” adds Schmitt. “The simpler the system, the better the system.”
