Mastercard to Secure Mobile Payments with Geotagging

MasterCard, Syniverse To Secure Mobile Payments Abroad By Barry Levine, Newsfactor Business Report, February 25, 2014

Geotagging is a key aspect of the new, pay-when-you’re-abroad service planned by MasterCard and Syniverse, allowing mobile users to be authorized when they’re in a new country, as well as enabling appropriate data plans and marketing services. But it’s geotagging that knows your mobile device and your credit card are in the same place.

Protecting Location Privacy Against Inference Attacks

Kazuhiro Minami and Nikita Borisov, 2010. Protecting location privacy against inference attacks. In Proceedings of the 9th annual ACM workshop on Privacy in the electronic society (2010), pp. 123-126.

GPS-enabled mobile devices are a quickly growing market and users are starting to share their location information with each other through services such as Google Latitude. Location information, however, is very privacy-sensitive, since it can be used to infer activities, preferences, relationships, and other personal information, and thus access to it must be carefully protected. The situation is complicated by the possibility of inferring a users’ location information from previous (or even future) movements. We argue that such inference means that traditional access control models that make a binary decision on whether a piece of information is released or not are not sufficient, and new policies must be designed that ensure that private information is not revealed either directly or through inference. We provide a formal definition of location privacy that incorporates an adversary’s ability to predict location and discuss possible implementation of access control mechanisms that satisfy this definition. To support our reasoning, we analyze a preliminary data set to evaluate the accuracy of location prediction.

Projects Use Phone Data to Track Public Services – NYTimes.com

By Joshua Brunstein, NYT, June 5, 2011

…The city’s Metropolitan Transportation Authority has been trying to provide a better sense of predictability in recent years by adding displays in stations that state when the next train is expected. Now, a Web development firm called Densebrain says that it can do the same thing at practically no cost, by analyzing how people lose phone service when they head underground. Urban planners, technology companies and officials from local governments see potential in projects like these that mine data collected from phones to provide better public services. …

FEMA’s Personal Localized Alerting Network Just Touches the Surface

Emergency Management Blog – Eric Holdeman, May 22, 2011

Yesterday’s announcement that cell broadcast alerts will be available soon in New York City just touches the surface of a comprehensive plan. FEMA, the FCC, the Mayor of New York and cellular company executives announced that a program called PLAN, Personal Localized Alerting Network, will be launched in NYC late this year. … A number of important points:

1. The word “launch” is important. What was announced was that new mobile devices shipped to NYC will soon be equipped to receive the alerts. That doesn’t mean that all mobile devices will receive them…only new ones from participating carriers. (Most major carriers are participants.) …

By David Talbot, MIT Technology Review, March 28, 2011

From Libya to Japan, a Web-reporting platform called Ushahidi has helped human rights workers and others document and make sense of fast-moving crises. The platform allows reports from cell phones and Web-connected devices to be collected and displayed on Web-based maps. Now Ushahidi is adding a concept borrowed from location-based social networking, as well as layers of private access—functionality that could make the service more efficient and useful in politically charged circumstances. …

Legal Symposium on Mobile Devices, Location Technologies and Shifting Values

Fifth Annual Law & Information Society Symposium: Mobile Devices, Location Technologies & Shifting Values

Date(s):
03.25.11 Fri
Time: 9:00 a.m. – 5:30 p.m.
Location: Lowenstein Building, 12th Floor Lounge

In celebration of CLIP’s Fifth Anniversary, this symposium will explore emerging law and policy related to mobile devices, location technologies and shifting public values. Advances in information and network technologies have placed mobile computing at the forefront of the global information economy. The popularity of devices like smart phones and of applications providing location based services have led to an increase in information collection and information accessibility. At the same time, values and societal expectations with respect to key issues such as access to networks, use of content, and privacy are shifting. This symposium will bring together thought-leaders and practitioners to address and assess policies and solutions for the cutting-edge issues that will affect the evolution of mobile computing.

8:30 – 9:00 Registration and Breakfast

9:00 – 9:10 Welcome

9:10 – 9:30 Mobile Computing 101

This introductory presentation will provide a technological primer on mobile devices and location technology. Topics covered will include: What location data is currently being collected and by whom? How is this location data being used? What are location based services (LBS)? What consumer and business LBS are on the horizon?

Speaker: Matt Blaze, Associate Professor of Computer Science, University of Pennsylvania

9:30 – 11:00 Panel 1: Evolving Values Regarding Locational Privacy

Have mobile devices and location based services changed our values regarding privacy, data collection and data use? This panel will explore the privacy concerns that arise as people begin turning over and technologies disclose more information in order to use mobile devices and LBS. What rights do individuals have in the data collected? What rights do people expect and are expectations changing as these services become more popular? What rights are granted/recognized internationally and how can compliance with local and international standards be assured? What rights should corporations ethically grant their users?
