An Architecture for Privacy-Sensitive Ubiquitous Computing

Profile image of James A. LandayJames A. Landay

Abstract

Privacy is the most often-cited criticism of ubiquitous computing, and may be the greatest barrier to its long-term success. However, developers currently have little support in designing software architectures and in creating interactions that are effective in helping end-users manage their privacy. To address this problem, we present Confab, a toolkit for facilitating the development of privacy-sensitive ubiquitous computing applications. The requirements for Confab were gathered through an analysis of privacy needs for both end-users and application developers. Confab provides basic support for building ubiquitous computing applications, providing a framework as well as several customizable privacy mechanisms. Confab also comes with extensions for managing location privacy. Combined, these features allow application developers and end-users to support a spectrum of trust levels and privacy needs.

Privacy Infusion in Ubiquitous Computing
DRX MOHAN KUMAR

2007 Fourth Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services (MobiQuitous), 2007

In recent years, ubiquitous computing applications span such areas as telemedicine, banking, and transportation that require user privacy protection. The realization of contextaware ubiquitous computing exasperates existing privacy concerns. Ubiquitous computing applications demand new privacy enhancing technologies for the information and communication environments where the users are equipped with flexible and portable applications to support the capture, communication, recall, organization and reuse of diverse information. In this paper, we develop a novel scheme for the infusion of privacy into context-aware ubiquitous computing. We present Precision, a system for privacy enhanced context-aware information fusion in ubiquitous computing environments. In our scheme, privacy is defined as a set of parameters encapsulated in composite data entities called privons, through which, we aim at infusing privacy into Precision. We evaluate our proposed scheme through real interactions in implementation of privons.

Managing personal information disclosure in ubiquitous computing environments
Anind Dey

2003

Ubiquitous computing stands to redefine established notions of pr ivacy as it introduces regular, pervasive sensing of personal information such as identity, location, and activity. To effectively and comfortably manage the di sclosure of personal information, end-users will require a coherent conceptual model of privacy and convenient user interfaces to manage it. We describe a conceptual framework designed to support personal privacy management in ubiquitous computing by empowering users to adjust the precision of disclosed information. The framework relies on three key strategies: encapsulation, a priori configuration, and manual configuration. We describe a prototypical user i nterface built to instantiate this framework and we report the results of a formative evaluation of the framework. Results show our approach is superior to simple, automated disclosure paradigms but can be further refined.

A Privacy Service for Context-aware Mobile Computing
Fernando Nascimento

2005

Privacy issues related to the access of context information are becoming increasingly important as we move toward ubiquitous and mobile computing environments. In this article, we describe the design and implementation of a privacy service, called Context Privacy Service (CoPS), to control how, when and to whom disclose a user's context information. Based on the results of an end-user survey and experience reported by other research groups, we identified the main service requirements and designed CoPS aiming flexibility, generality, simplicity and fine-grained privacy control. CoPS is an optional service of our context-provisioning middleware MoCA and allows users of context-and location-aware applications to define and manage their privacy policies regarding disclosure of their context information. The main features supported by CoPS are group-based access control, pessimistic and optimistic approaches for access control, hierarchical privacy rules, mixed-initiative interaction, and rule specificity analysis.

Exploring privacy for ubiquitous computing: Tools, methods and experiments
Mika Raento

2007

Ubiquitous computing is about making computers and computerized artefacts a pervasive part of our everyday lifes, bringing more and more activities into the realm of information. The computationalization, informationalization of everyday activities increases not only our reach, efficiency and capabilities but also the amount and kinds of data gathered about us and our activities. In this thesis, I explore how information systems can be constructed so that they handle this personal data in a reasonable manner. The thesis provides two kinds of results: on one hand, tools and methods for both the construction as well as the evaluation of ubiquitous and mobile systems-on the other hand an evaluation of the privacy aspects of a ubiquitous social awareness system. The work emphasises real-world experiments as the most important way to study privacy. Additionally, the state of current information systems as regards data protection is studied.

Privacy and security in ubiquitous personalized applications
J. Kay

2004

Personalization systems provide customized service based on user preferences. In ubiquitous computing environments, personalization can be achieved based on user preferences stored on mobile devices. This requires a mechanism for capturing user information and making it available to users. However, storing and exchanging potentially personal information raises user privacy concerns. Past solutions to privacy in ubiquitous computing have been ad-hoc, application specific or partially implemented. This work explores a general framework to providing privacy-aware personalization in ubiquitous computing environments. A prototype implementation of the framework has been developed and evaluated. This paper describes the approach used and its underlying concepts.

Privacy mirrors: understanding and shaping socio-technical ubiquitous computing systems
Elizabeth Mynatt

2002

Privacy is a known issue in ubiquitous computing, exasperated by an oft-cited feature of ubiquitous computing -invisibility. Dangers of invisible computing are interfaces that do not give people the needed tools of awareness and control to understand and shape the behavior of the system. By definition, ubiquitous computing systems are socio-technical, encompassing three environments: social, technical, and physical. We argue that addressing or presenting solutions in any one environment alone cannot solve the privacy issue in ubiquitous computing. Privacy is addressed best by giving users methods, mechanisms, and interfaces to understand and then shape the system in all three environments. We introduce Privacy Mirrors, a framework for designing socio-technical ubiquitous computing systems that will integrate into people's on-going needs, practices, values, and aesthetic sensibilities.

Ubiquitous Privacy Protection Position Paper
Joël Moret-Bailly

2007

The main message of this position paper is that ubiquitous computing technology need not necessarily be an obstacle to privacy protection: if legal and social issues are given proper consideration, technology can also be used to allow individuals to exercise their rights. We believe that the key issue is to devise techniques able to support ambitious privacy protection policies while allowing for the flexibility required in the ambient intelligence context. We illustrate our position using three technical requirements: (1) formal specification of privacy policies, (2) trust management and (3) auditability, which show both the challenges posed by ubiquitous computing and the opportunities to strengthen privacy. For each of these requirements, we present the legal and social motivations, suggest technical challenges and provide hints on possible solutions based on our on-going work.

Keeping ubiquitous computing to yourself: A practical model for user control of privacy
Blaine Price

International Journal of Human-Computer Studies, 2005

As with all the major advances in information and communication technology, ubiquitous computing (ubicomp) introduces new risks to individual privacy. Our analysis of privacy protection in ubicomp has identified four layers through which users must navigate: the regulatory regime they are currently in, the type of ubicomp service required, the type of data being disclosed, and their personal privacy policy. We illustrate and compare the protection afforded by regulation and by some major models for user control of privacy. We identify the shortcomings of each and propose a model which allows user control of privacy levels in a ubicomp environment. Our model balances the user's privacy preferences against the applicable privacy regulations and incorporates five types of user controlled "noise" to protect location privacy by introducing ambiguities. We also incorporate an economics-based approach to assist users in balancing the trade-offs between giving up privacy and receiving ubicomp services. We conclude with a scenario and heuristic evaluation which suggests that regulation can have both positive and negative influences on privacy interfaces in ubicomp and that social translucence is an important heuristic for ubicomp privacy interface functionality.

Towards context adaptive privacy decisions in ubiquitous computing
Florian Schaub

2012

In ubiquitous systems control of privacy settings will be increasingly difficult due to the pervasive nature of sensing and communication capabilities. We identify challenges for privacy decisions in ubiquitous systems and propose a system for in situ privacy decision support. When context changes occur, the system adapts a user's privacy preferences to the new situation. As a consequence, recommendations can be offered to the user or sharing behavior can be automatically adjusted to help the user maintain a desired level of privacy. The system learns from user interaction and behavior to improve decision accuracy. In this paper, we outline the main components of our system and illustrate its operation with an ambient assisted living use case.

Designing for Privacy in Ubiquitous Computing Environments
John Canny

2004

Abstract. In an Ubiquitous Computing environment, sensors are actively collecting data, much of which can be very sensitive. Data will often be streaming at high rates (video and audio) and it must be dealt with in real-time. Protecting the privacy of users is of central importance. Effective solutions for controlling access to data in ubicomp settings remain to be developed. Dealing with these issues will be a central challenge for ubicomp for some time to come.

"Participatory applications provide users with valueadded and reusable information; however, collection of this information comes at the expense of the participants’ privacy. Preserving the mobile participants’ privacy is a key concern of mobile computing. This paper outlines current participatory application system model, privacy weaknesses, and existing privacy enhancing technologies. Next, it proposes a study to address mobile privacy protection by educating participants of exploitable privacy areas of their participatory applications. The contribution of the paper is two-fold: it provides a review of the existing privacy weaknesses of PS applications and demonstrates that participants’ wanting to know more about these weaknesses warrants further study."

Everyday privacy in ubiquitous computing environments
Anind Dey

Ubicomp 2002 Workshop on Socially- …, 2002

We present a conceptual model of everyday privacy in ubiquitous computing environments, based on the works of Lessig and Adams. By everyday privacy, we mean the enduser's ongoing exposure to and control over personal information collection. The model accounts for the influence of societal-scale forces, contextual factors, and subjective perception on end-user privacy. We identify notice and consent as the fair information practices of greatest everyday utility to users, as they gradually engender the user's conceptual model of ubicomp privacy. Navigating the regular deluge of personal information collection events in ubicomp requires that notice be minimally intrusive and consent be implicitly granted by a persistent, situation-specific set of user preferences. We extend our model into an interactional metaphor called faces, designed to mitigate the complexity of privacy for the end-user. Users vary the face they wear depending on the recipient and/or situation, where a face is a meaningful encapsulation of privacy preferences.
