Contextualized Communication of Privacy Practices and Personalization Benefits: Impacts on Users’ Data Sharing and Purchase Behavior

Abstract

Abstract. Consumer surveys demonstrated that privacy statements on the web are ineffective in alleviating users' privacy concerns. We propose a new user interface design approach in which the privacy practices of a website are explicated in a contextualized manner, and users' benefits in providing personal data clearly explained. To test the merits of this approach, we conducted a user experiment that compared two versions of a personalized web store: one with a traditional global disclosure and one that additionally provides contextualized explanations of privacy practices and personalization benefits. We found that subjects in the second condition were significantly more willing to share personal data with the website, rated its privacy practices and the perceived benefit resulting from data disclosure significantly higher, and also made considerably more purchases. We discuss the implications of these results and point out open research questions.

Internet of Everything (Ioe): Analysing the Individual Concerns Over Privacy Enhancing Technologies (Pets)

“…On the other side, the privacy-by-architecture concludes that individuals have no right to say anything about their personal information. The individuals may have their perspective concerns and if they are not heard and managed up to their contents, this approach would be seen as an unwelcome outcome [25].…”

Privacy Considerations in Awareness Systems: Designing with Privacy in Mind

“…-encryption [Diffie and Hellman 1979]; -access control via preferences, policies, and roles [Edwards 1996;Wickramasuriya, Datt et al 2004]; -mechanisms to reduce the burden of preference specification such as lightweight interfaces [Lau, Etzioni et al 1999], or grouping and templates [Olson, Grudin et al 2005;Patil and Lai 2005]; -automatic or manual control of the granularity of disclosed information [Dourish and Bly 1992;Lee, Girgensohn et al 1997;Palen 1999;Consolvo, Smith et al 2005]; -feedback via visualization [Gross, Wirsam et al 2003], sound [Gaver, Moran et al 1992], intelligent agents , and contextual disclosure [Kobsa and Teltzrow 2005]; -distortion of disclosed information [Boyle, Edwards et al 2000]; -support for anonymity (or pseudonymity) [Appelt 1999]; -inference of appropriate awareness disclosure based on modeling [Begole, Tang et al 2002]. Describing these techniques is beyond the scope of this chapter.…”

Privacy protection without impairing personalization by using the extended system MASKS and the extended contextualized P3P privacy policies

“…Kobsa [13] presents a framework for the disclosure contextualized of privacy practices and personalization benefits. This method notifies the user according to the context he/she is.…”

“…Developing project presented by Kobsa [13] applies when orienting privacy policies construction and increasing information disclosed is necessary. For a page or a set of pages, there is contextual and specifically built P3P privacy policy.…”
