Information security is a major concern nowadays in our day-to-day life

Global Navigation Satellite Systems (GNSS) are increasingly being used in safety- and security-critical applications such as aviation, autonomous vehicles, and emergency services, as well as synchronization within communication systems, financial infrastructures, power grids, etc. However, they are vulnerable to several threats.

The INSURE project contributed to create beyond state-of-the-art knowledge for improving robustness of GNSS receivers against interference threats. Within this scope, the INSURE team developed a practical solution for GNSS interference detection and mitigation.

The security of location information on the societal scale but also on a personal level has been one of the main focuses of the INSURE project. In a time when positioning services and precision timing are critically important in many parts of society the protection of location information generated by personal devices are often overlooked.

Security and privacy aspects of localization are presented in more detail in the publication “Robustness, Security and Privacy in Location-Based Services in Future IoT: A Survey,” by L.Chen et al. 2017

The research in UH-CS focused primarily on privacy-enhancing technologies to protect users’ location privacy in different use cases. The most prominent results were obtained in privacy-preserving indoor localization utilizing different approaches for secure multi-party computation says Kimmo Järvinen, University of Helsinki.

The TUT team investigated several aspects of non-GNSS positioning; the principal findings and outcomes are:
– An assessment of location privacy challenges and the outline of their solutions (corresponding article is “Location privacy challenges and solutions” in InsideGNSS).
– An analysis of the robustness of fingerprinting-based positioning methods towards a wide range of attacks (corresponding publication is “Attack Tolerance of RSS-based Fingerprinting” from WCNC conference 2018).
– The design of a privacy-preserving fingerprinting-based positioning method in collaboration with the University of Helsinki and the Technical University Darmstadt. One outcome of that collaboration is “Received Signal Strength quantization for secure indoor positioning via fingerprinting” from ICL GNSS 2018. Another one, presenting the complete scheme, is under review.

During the INSURE project the issues of localization versus privacy have been discussed and approached by researchers from different angles. In May 2018 more than 60 students and representatives for companies discussed these issues for three days in the Summer School in Otaniemi, Espoo.

INSURE project brought together researchers from Finnish Geospatial Research Institute, Tampere University of Technology and University of Helsinki to work with information security in localization. The overall impression at the final meeting in Masala in August was that Insure has been a very successful project.

The project has resulted in more than 40 publications, such as “The Death and Rebirth of Privacy-Preserving Wifi Fingerprint Localization with Paillier Encryption”, by Z. Yang and K. Järvinen,( IEEE INFOCOM 2018), “Robustness, Security and Privacy in Location-Based Services in Future IoT: A Survey,” by L. Chen, S. Thombre, K. Järvinen, E.S Lohan, A. Alen-Savikko, H. Leppäkoski, M.Z.H.Bhuiyan, S. Bu-Pasha, G.N. Ferrara, S. Honkala, J. Lindqvist, L.Ruotsalainen, P. Korpisaari and H. Kuusniemi, (2017) IEEE Access, Vol. 5, and “A New Implementation of Narrowband Interference Detection, Characterization and Mitigation Technique for a Software-defined multi-GNSS Receiver,” by N.G. Ferrara, M.Z.H. Bhuiyan, S. Söderholm, L. Ruotsalainen and H.Kuusniemi (2018) GPS Solutions, Vol. 22, No. 4.
