Geographic Privacy-aware Knowledge Discovery and Delivery


FET - Open

A flood of data pertinent to moving objects is available today, and will be more in the near future, particularly due to the automated collection of privacy-sensitive telecom data from mobile phones and other location-aware devices. Such wealth of data, referenced both in space and time, may enable novel classes of applications of high societal and economic impact, provided that the discovery of consumable and concise knowledge out of these raw data is made possible. The goal of the GeoPKDD project is to develop theory, techniques and systems for geographic knowledge discovery and delivery, based on new privacy-preserving methods for extracting knowledge from large amounts of raw data referenced in space and time. More precisely, we aim at devising knowledge discovery and analysis methods for trajectories of moving objects; such methods will be designed to preserve the privacy of the source sensitive data. The fundamental hypothesis is that it is possible, in principle, to aid citizens in their mobile activities by analyzing the traces of their past activities by means of data mining techniques. For instance, behavioral patterns derived from mobile trajectories may allow inducing traffic flow information, capable to help people travel efficiently, to help public administrations in traffic-related decision making for sustainable mobility and security management, as well as to help mobile operators in optimizing bandwidth and power allocation on the network. However, it is clear that the use of personal sensitive data arouses concerns about citizen's privacy rights. Obtaining the potential benefits by means of a trustable technology, designed to prevent infringing privacy rights, is a highly innovative goal; if fulfilled, it would enable a wider social acceptance of many new services of public utility that would find in the advocated form of geographic knowledge a key driver, such as in transport, environment and risk management.
