Up to now, cloud-based processing of positioning data (e.g. samples, raw measurements, anonymised Position, Velocity and TimePVT) has always been susceptible to data breaches and raised concerns about privacy protection. Location-based services can fail in their path to wide-spread adoption, because they are perceived as invasive by the users and fail to properly address their risks. By shifting the privacy control on the user side and also decentralise processing with the involvement of the user, trusted services can be built without having to rely on the security of the infrastructure. One can bear the full responsibility for its data if, for example, if allowed to act in anonymity or to encrypt its information before it is shared for processing. Different techniques can be envisioned to avoid disclosing sensitive data. For example, homomorphic encryption allows the manipulation and processing of encrypted data sets without the need of revealing any of the original data. This enables third parties such as cloud service providers to apply various functions over the user’s data while not infringing upon any privacy barriers. The user maintains all its information and encryption keys private, and computationally intensive operations are blindly performed by dedicated servers. Moreover, to prevent security breaches, multi resolution sharing allows the user to control the granularity of information shared to different users. Other crypto technologies such as blockchain can enable a community data sharing protocol robust against tampering from malevolent parties. Many applications could be considered: contact tracing for establishing risk of infection and minimizing the spread, incident awareness for users in areas affected by natural disasters or in an emergency state, automatic tolling for passenger cars, enforcing regulations on the airspace used by autonomous drones or distributed secure processing of GNSS signals. This activity aims at developing innovative privacy-preserving Position, Navigation and Timing (PNT) processing concepts based on the use of cryptographic techniques and distributed processing architectures.
