The carrier claims the new system is needed to “save the targeted advertising industry”.

Vodafone is piloting a new advertising ID system called TrustPid, which will work as a persistent user tracker at the mobile Internet Service Provider (ISP) level. This is according to a report in BleepingComputer.

The new system is in test phase in Germany, where Deutsche Telekom is also piloting the new ID. The TrustPid system is intended to be impossible to bypass from within the web browser settings or through cookie blocking or IP address masking.

The mobile carrier plans to assign a fixed ID to each customer and associate all user activity with it. The ID will be based on a number of parameters, so that the system will be able to maintain persistence.

Then, the mobile ISP creates a personal profile based on that ID and helps advertisers serve targeted ads to each customer without disclosing any identification details.

The cost of keeping the Internet “free”

According to Vodafone, the problem that arises for its internet subscribers is that the “free” parts of the internet are threatened by stricter cookie blocking and privacy-boosting schemes.

Apple already blocks default tracking everywhere, which destroyed Facebook’s business model, and Google is also expected to switch off its advertising cookie in Chrome by 2023.

These new models threaten the targeted advertising industry, and according to Vodafone, the danger of this is losing content and platforms currently supported by ads.

The industry is looking for alternative tracking ways, and mobile ISPs are in a position to provide a solution that users are likely to find difficult to circumvent.

Patrick Breyer, member of the European Parliament and digital rights activist, has told BleepingComputer the following:

“The online activities of an individual allow for deep insights into their (past and future) behavior and make it possible to manipulate them. These personality profiles, which even cover political opinion, sexual orientation, or medical conditions, are a risk to privacy but also to national security, where officials can be blackmailed, and also to democracy, where elections and referendums can be manipulated. A unique ID would allow for monitoring our entire digital lives.

“These schemes are totally unacceptable and the trials should be stopped,” Breyer declared. “Democracy is not for sale.”
