In each of these domains, data integrity and device-owners' privacy are first-class concerns, but current approaches to secure sensing fail to balance these properties. External signing infrastructure cannot attest to the values generated by a device's sensing hardware, while trusted sensing hardware does not allow users to securely reduce the fidelity of readings in order to preserve their privacy. In this paper we examine the challenges posed by the potentially conflicting goals of data integrity and user privacy and propose a trustworthy mobile sensing platform which leverages inexpensive commodity Trusted Platform Module (TPM) hardware.","PeriodicalId":88972,"journal":{"name":"Proceedings.

This trend makes smart phone operating systems vulnerable to many of the same threats as desktop operating systems.\u0000 In this paper, we focus on the threat posed by smart phone rootkits. Rootkits are malware that stealthily modify operating system code and data to achieve malicious goals, and have long been a problem for desktops. We use three example rootkits to show that smart phones are just as vulnerable to rootkits as desktop operating systems. However, the ubiquity of smart phones and the unique interfaces that they expose, such as voice, GPS and battery, make the social consequences of rootkits particularly devastating. We conclude the paper by identifying the challenges that need to be addressed to effectively detect rootkits on smart phones.","PeriodicalId":88972,"journal":{"name":"Proceedings.

Today, smartphones using these applications act as simple clients and send out user locations to untrusted third-party servers. These servers have the application logic to provide the service, and in the process collect large amounts of user location information over time. This design, however, is shown to be susceptible to large-scale user privacy compromises even if several location cloaking techniques are employed. In this position paper, we argue that the LBSAs should adapt an approach where the untrusted third-party servers are treated simply as encrypted data stores, and the application functionality be moved to the client devices. The location coordinates are encrypted, when shared, and can be decrypted only by the users that the data is intended for. This approach significantly improves user location privacy. We argue that this approach not only improves privacy, but it is also flexible enough to support a wide variety of location-based applications used today. In this paper, we identify the key building blocks necessary to construct the applications in this approach, give examples of using the building blocks by constructing several applications, and outline the privacy properties provided by this approach. We believe our approach provides a practical alternative design for LBSAs that is deployable today.","PeriodicalId":88972,"journal":{"name":"Proceedings.

The original application executes on a machine running remote desktop software (such as VNC server) without any modifications. Users can utilize the Merlion Designer to select relevant visual regions of the original application and create an alternate layout that is more suitable to their circumstances (e.g. taking the screen real-estate of their mobile device into account). Once the custom application has been designed, the user can utilize the Merlion Runtime (running on the user's mobile device) to interact with their custom application. Merlion can improve user productivity by simplifying user interfaces, automate repetitive actions, make applications available across different mobile form factors, and can allow applications that work on different OS platforms to operate in concert. In this paper, we describe the design of the Merlion system, details of our initial prototype, and discussion of the benefits and challenges of our approach.","PeriodicalId":88972,"journal":{"name":"Proceedings.

Alternative solutions that run the recognizer on a remote server will not be as desirable because of the delay between image capture and receipt of a result that can cause users to abandon the technique. We present a method for mobile recognition of paper documents and an application to newspapers that lets readers retrieve electronic data linked to articles, photos, and advertisements. We show that the index for a reasonable collection of daily newspapers can be downloaded in less than a minute and will fit in the memory of today's mid-range smart phones. Experimental results show that the recognition system has an overall error rate of less than 1%.

Users can fabricate sensor readings with relatively little effort. This lack of trust discourages the emergence of applications where users have an incentive to lie about their sensor readings, such as falsifying a location or altering a photo taken by the camera.\u0000 This paper presents a broad range of applications that would benefit from the deployment of trusted sensors, from participatory sensing to monitoring energy consumption. We present two design alternatives for making sensor readings trustworthy. Although both designs rely on the presence of a trusted platform module (TPM), they trade-off security guarantees for hardware requirements. While our first design is less secure, it requires no additional hardware beyond a TPM, unlike our second design. Finally, we present the privacy issues arising from the deployment of trusted sensors and we discuss protocols that can overcome them.","PeriodicalId":88972,"journal":{"name":"Proceedings.

Existing architectures for the generation and verification of such location proofs have limited flexibility. For example, they do not support the proactive gathering of location proofs, where, at the time of acquiring a location proof, a user does not yet know for which application or service she will use this proof. Supporting proactive location proofs is challenging because these proofs might enable proof issuers to track a user or they might violate a user's location privacy by revealing more information about a user's location than strictly necessary to an application. We present six essential design goals that a flexible location proof architecture should meet. Furthermore, we introduce a location proof architecture that realizes our design goals and that includes user anonymity and location privacy as key design components, as opposed to previous proposals. Finally, we demonstrate how some of the design goals can be achieved by adopting proper cryptographic techniques.","PeriodicalId":88972,"journal":{"name":"Proceedings.

However, mobile devices are fundamentally different from desktop PCs in terms of input speeds, screen size, and network speeds, making it harder in practice to find information when on the go. In this paper, we introduce GurunGo, a system that monitors a person's activities on their PC for mobile data types---kinds of data likely to be useful to a person when mobile---and then proactively copies these snippets of data onto his mobile device, thus making it easier to find that information when mobile. Our initial prototype finds and extracts mobile data types from web pages that are browsed on a desktop computer, annotates it with additional relevant information, and copies it to a mobile device in the background. We discuss the design and implementation of GurunGo, as well as some of the tradeoffs and design rationale.","PeriodicalId":88972,"journal":{"name":"Proceedings.
