Mapping the Space of Location-Based Services 5
CHARLIEDETAR MAPPINGTHESPACEOFLOCATION- BASEDSERVICES 2 charlie detar Abstract This paper is an attempt to both summarize the current state of Lo- cation Based Services (LBS), and to unpack and problematize the underlying assumptions on which they operate. Location based ser- vices — including applications for mapping and navigation, social networking, gaming, and tourism and information services — are all based on the idea that information about a user’s location can be used to adapt the content and user interface of a service, improving it. However, the “location” used by these systems is usually restricted to data-poor representations such as geographic coordinates, and as such provides an insufficient cue for the rich and culturally contin- gent context embodied in the notion of a “place”. I will argue that developers should consider both the salience of the particular place- or space-based context to their application domain, and the potential impacts the application will have on a user’s sense of place when designing location based services.

The concept of “place” combines both geography and sociality — one has a “place” in relation to other people (and deviant behavior is “out of place”). -

Where these services are directed at the general public, extra care is required because of the ongoing debate over privacy of location data. If you were to survey an expert panel of mobile and web professionals about what they thought was the number-one hurdle to a wider and faster spread of LBS, we’d bet a large sum of money that their answer would be “privacy concerns.” More and more, the terms privacy and location are mentioned together (try Googling for the two terms together, and you’ll get over 1,980,000,000 entries), and the driver behind this is that people value their locational privacy above all 214 What do we mean by privacy? 215 other types of privacy (religious privacy, cultural privacy, behavioral privacy, and so on). -

Privacy Considerations for Secure Identification in Social Wireless
Privacy considerations for secure identification in social wireless networks Master’s degree thesis ELENA KOZHEMYAK Academic supervisor: Sonja Buchegger, KTH External supervisor: Christian Gehrmann, SICS Examiner: Johan Håstad, KTH September 2011 iii Abstract This thesis focuses on privacy aspects of identification and key exchange schemes for mobile social networks. In particular, we consider identification schemes that combine wide area mobile communication with short range com- munication such as Bluetooth, WiFi. The goal of the thesis is to identify possi- ble security threats to personal information of users and to define a framework of security and privacy requirements in the context of mobile social networking. The main focus of the work is on security in closed groups and the procedures of secure registration, identification and invitation of users in mobile social net- works. The thesis includes an evaluation of the proposed identification and key exchange schemes and a proposal for a series of modifications that augments its privacy-preserving capabilities. The ultimate design provides secure and ef- fective identity management in the context of, and in respect to, the protection of user identity privacy in mobile social networks. Keywords: mobile social networks, identity privacy, identity management, pseudonyms. iv Sammanfattning Det här examensarbetet handlar om personlig integritet, identifiering och nyckelutbyte i mobila sociala nätverk. Speciellt adresserar vi dessa aspekter för system som kombinerar mobil kommunikation med kort räckviddskommunika- tion som Bluetooth och WiFi. Målet med detta arbete är att identifiera möjliga säkerhetshot mot användarinformation och att ta fram ett ramverk för säkerhet och krav på personlig integritet i mobila sociala nätverk. Tyngdpunkten i ar- betet ligger på säkerhet i slutna grupper och förfaranden för säker registrering, identifiering och inbjudan av användare i mobila sociala nätverk. -

Privacy Leakage in Mobile Online Social Networks
Privacy Leakage in Mobile Online Social Networks Balachander Krishnamurthy, AT&T Labs – Research Craig E. Wills, Worcester Polytechnic Institute Workshop on Online Social Networks Boston, MA USA June 2010 1 Introduction Previously studied the leakage of personally identifiable information via Online Social Networks (OSNs) to third-party aggregators. Trend towards use of mobile devices to access OSNs (Facebook reports 25% of users access OSN via a mobile device every month). Also development of new OSNs—mobile OSNs (mOSNs)—that primarily cater to mobile users. Examples include Brightkite, Foursquare, Gowalla, Loopt, Urbanspoon, Whrrl. Mobile access to Web sites designed specifically for mobile devices and through the development of “apps” that are specific to a site and to a mobile platform. 2 New Privacy Concerns Mobile devices potentially introduce new privacy concerns for mOSNs. These include: • user presence and geographic location • information shared with a mOSN connected to a traditional OSN is also shared with that OSN • unique device identifiers Examine the degree to which leakage of private information is occurring via mOSNs.

Location-Sharing Technologies: Privacy Risks and Controls
Location-Sharing Technologies: Privacy Risks and Controls Janice Y. Tsai, Patrick Gage Kelley, Lorrie Faith Cranor, Norman Sadeh Carnegie Mellon University Pittsburgh, PA [email protected], [email protected], [email protected], [email protected] Updated February 2010 Abstract. Due to the ability of cell phone providers to use cell phone towers to pinpoint users’ locations, federal E911 requirements, the increasing popularity of GPS-capabilities in cellular phones, and the rise of cellular phones for Internet use, a plethora of new applications have been developed that share users’ real-time location information online [27]. This paper evaluates users’ risk and benefit perceptions related to the use of these technologies and the privacy controls of existing location-sharing applications. We conducted an online survey of American Internet users (n = 587) to evaluate users’ perceptions of the likelihood of several location-sharing use scenarios along with the magnitude of the benefit or harm of each scenario (e.g. being stalked or finding people in an emergency). We find that although the majority of our respondents had heard of location-sharing technologies (72.4%), they do not yet understand the potential value of these applications, and they have concerns about sharing their location information online. Most importantly, participants are extremely concerned about controlling who has access to their location. Generally, respondents feel the risks of using location-sharing technologies outweigh the benefits. Respondents felt that the most likely harms would stem from revealing the location of their home to others or being stalked. People felt the strongest benefit were being able to find people in an emergency and being able to track their children. -
