Mobility, Data Mining and Privacy - Preserving anonymity in geographically referenced data

First Interdisciplinary Workshop onMobility, Data Mining and PrivacyPreserving anonymity in geographically referenced

Rome, Italy - 14 February 2008

Organized by the European project GeoPKDD Geographic Privacy-aware Knowledge Discovery and Delivery (IST-FET project n. 014915).




The technologies of mobile communications and ubiquitous computing pervade our society, and wireless networks sense the movement of people and vehicles, generating large volumes of mobility data. This is a scenario of great opportunities and risks: on one side, mining this data can produce useful knowledge, supporting sustainable mobility and intelligent transportation systems; on the other side, individual privacy is at risk, as the mobility data contain sensitive personal information. A new multidisciplinary research area is emerging at this crossroads of mobility, data mining, and privacy. In this context, the workshop aims at fostering the interdisciplinary dialogue among researchers and professionals in computer science, law, geography, social sciences, statistics, telecommunication and transportation engineering.

A new startup called YourStreet is bringing hyper-local information to its users by collecting news stories and placing them on its map-based interface, down to the nearest street corner. While there have been many companies that combine information and maps, YourStreet is novel in its focus on classifying news by location. (See "A New Perspective on the Virtual World.")

When a user opens the site, it detects her location and shows a map of that area, stuck with pins that represent the locations of news stories, user-generated content called conversations, and people who have added themselves to the map. The user can zoom in or out of the map or look at another location by entering a place name or zip code into a search bar. CEO and founder James Nicholson says that what sets YourStreet apart is its extensive news service: the site collects 30,000 to 40,000 articles a day from more than 10,000 RSS feeds, mostly from community newspapers and blogs. "We're not relying on the users to provide us with articles," Nicholson says. The stories featured on the site aren't of a specific type, and users will find the locations of murders marked alongside the locations of upcoming music shows. Stories featured on the site are teasers, and, if a user clicks to read further, she will be directed back to the source of the information.

Finding Yourself without GPS

Finding Yourself without GPS

Google's new technology could enable location-finding services on cell phones that lack GPS.

As more mobile phones tap into the Internet, people increasingly turn to them for location-centric services like getting directions and finding nearby restaurants. While Global Positioning System (GPS) technology provides excellent accuracy, only a fraction of phones have this capability. What's more, GPS coverage is spotty in dense urban environments, and in-phone receivers can be slow and drain a phone's battery.

To sidestep this problem, last week Google added a new feature, called My Location, to its Web-based mapping service. My Location collects information from the nearest cell-phone tower to estimate a person's location within a distance of about 1,000 meters. This resolution is obviously not sufficient for driving directions, but it can be fine for searching for a restaurant or a store. "A common use of Google Maps is to search nearby," says Steve Lee, product manager for Google Maps, who likened the approach to searching for something within an urban zip code, but without knowing that code. "In a new city, you might not know the zip code, or even if you know it, it takes time to enter it and then to zoom in and pan around the map."
