PRECIOSA (PRivacy Enabled Capability In Co-Operative Systems and Safety Applications)

Pervasive (or ubiquitous) computing is developing rapidly. Even today a wide variety of devices are available to consumers such as routing systems, locators, intelligent travel guides, or personalized devices. With the development of further application scenarios and new services we expect enhanced devices. Besides their benefits the emerging pervasive environments must also face new approaches for abuses and attacks. For example, many users are not aware of the exchange of personal data. Even if the exchanged data is not sensitive it may become sensitive in a broader context. Intelligent adversaries could combine observed data with additional information from other (external) sources such as digital repositories or knowledge bases to intrude the user’s privacy. Those adversaries may extract sensitive information and therefore may identify the corresponding individuals. This kind of violating the user’s privacy is called linkage attack.

In the context of the European Union PRECIOSA (Privacy Enabled Capability In co-Operative systems and Safety Applications) we investigate different attack and protection models in location-aware, mobile environments. We currently develop and implement various methods to prevent the observation of location based information that is considered sensitive for a particular user. Furthermore we intend to combine existing technologies on protecting privacy and mobility with technologies for the Semantic Web.
