Mobility has both negative and positive facets. On the negative side, mobility introduces new threats (e.g., sparse connectivity, wireless communication eavesdropping). On the positive side, the related notion of locality, when handled correctly, can be beneficial to system design. Both facets of mobility need to be studied in the context of resilient ubiquitous systems. Privacy protection of personal data is also a major challenge.
Our work at the architecture level addresses the design of innovative technologies that are aimed at giving people control over their personal information, and preventing applications and devices from disclosing personal information without the consent of their users [1, 2]. Our recent research in this context mainly focuses on privacy protection considering geolocated data.
From the analysis viewpoint, we address: i) the development of geoprivacy assessment techniques considering the particular problem of deanonymization of geolocated data, ii) the modeling of interactions in a mobile context and iii) the development of testing strategies for mobile applications.
