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. The new system is in test phase in Germany and 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.
