TL;DR: This work investigates learning algorithms that satisfy differential privacy, a notion that provides strong confidentiality guarantees in the contexts where aggregate information is released about a database containing sensitive information about individuals.
Abstract: Learning problems form an important category of computational tasks that generalizes many of the computations researchers apply to large real-life data sets. We ask: what concept classes can be learned privately, namely, by an algorithm whose output does not depend too heavily on any one input or specific training example? More precisely, we investigate learning algorithms that satisfy differential privacy, a notion that provides strong confidentiality guarantees in the contexts where aggregate information is released about a database containing sensitive information about individuals. We present several basic results that demonstrate general feasibility of private learning and relate several models previously studied separately in the contexts of privacy and standard learning.

TL;DR: In this paper, the consequences of consumers' privacy concerns in the context of mobile advertising are explored, and the proposed research model connects a series of psychological factors (prior negative experience, information privacy concerns, perceived ubiquity, trust, and perceived risk) and preference for degree of regulatory control.
Abstract: This study explores the consequences of consumers' privacy concerns in the context of mobile advertising. Drawing on social contract theory, the proposed research model connects a series of psychological factors (prior negative experience, information privacy concerns, perceived ubiquity, trust, and perceived risk) and preference for degree of regulatory control. Data from a survey of 510 mobile phone users in Japan show that mobile users with prior negative experiences with information disclosure possess elevated privacy concerns and perceive stronger risk, which leads them to prefer stricter regulatory controls in mobile advertising. Both perceived ubiquity and sensitivity of the information request further the negative impact of privacy concerns on trust. No such effect occurs for the impact of privacy concerns on perceived risk, however. The authors discuss some theoretical and managerial implications.

TL;DR: This work proposes a lightweight authenticated key establishment scheme with privacy preservation to secure the communications between mobile vehicles and roadside infrastructure in a VANET, called SECSPP, and integrates blind signature techniques into the scheme in allowing mobile vehicles to anonymously interact with the services of roadside infrastructure.

TL;DR: The perceived health status differentially moderates the effects of privacy concerns and informational support on the PHI disclosure intention, which significantly influence personal health information (PHI) disclosure intention.

TL;DR: In this article, the authors use a simple economic model to explore the conventional wisdom that privacy will continue to erode, until it essentially disappears, under the assumption that there is no government intervention and privacy is left to free-market forces.
Abstract: The World Wide Web has significantly reduced the costs of obtaining information about individuals, resulting in a widespread perception by consumers that their privacy is being eroded. The conventional wisdom among the technological cognoscenti seems to be that privacy will continue to erode, until it essentially disappears. The authors use a simple economic model to explore this conventional wisdom, under the assumption that there is no government intervention and privacy is left to free-market forces. They find support for the assertion that, under those conditions, the amount of privacy will decline over time and that privacy will be increasingly expensive to maintain. The authors conclude that a market for privacy will emerge, enabling customers to purchase a certain degree of privacy, no matter how easy it becomes for companies to obtain information, but the overall amount of privacy and privacy-based customer utility will continue to erode.
