Tools for Achieving Usable Ex Post Transparency: A Survey <s> 3) WEB-BASED SERVICE <s> This paper provides a short survey on transparency tools for privacy purposes. It defines the term transparency tools, argues why they are important and gives examples for transparency tools. A classification of transparency tools is suggested and some example tools are analyzed with the help of the classification. <s> BIB001 </s> Tools for Achieving Usable Ex Post Transparency: A Survey <s> 3) WEB-BASED SERVICE <s> The work presented in this paper introduces the concept of On-line Interactive (OI) privacy feature which is defined as any on-line interactive tool, component or user-interface that creates privacy awareness and supports users in understanding their on-line privacy risks. These features have been developed as an interactive social translucence map that discloses the flow of personal information, a privacy enquiry for a direct chat about users' privacy concerns and a discussion forum presenting users' privacy concerns using their language in an interactive FAQ format. The paper presents an evaluation of a prototype of this set of embedded OI privacy features. The field study presented evaluates the prototype's usability and its effect on users' privacy awareness, understanding and attitude. 100 participants took part in the study and were drawn from groups of experienced and less experienced users. Both quantitative and qualitative data collection methods were used. Findings suggest that OI privacy features increase users' privacy awareness and encourage users to find out more about the uses of their personal data. However, users' ICT skills and Internet experience significantly influence whether a feature is favoured or otherwise. In general, it is concluded that privacy features are very much welcomed and necessary to empower users to manage their privacy concerns but some groups need to be further supported by social and institutional privacy management processes. <s> BIB002 </s> Tools for Achieving Usable Ex Post Transparency: A Survey <s> 3) WEB-BASED SERVICE <s> Location-Based Mobile Service (LBMS) is one of the most popular smartphone services. LBMS enables people to more easily connect with each other and analyze the aspects of their lives. However, sharing location data can leak people's privacy. We present PDVLoc, a controlled location data-sharing framework based on selectively sharing data through a Personal Data Vault (PDV). A PDV is a privacy architecture in which individuals retain ownership of their data. Data are routinely filtered before being shared with content-service providers, and users or data custodian services can participate in making controlled data-sharing decisions. Introducing PDVLoc gives users flexible and granular access control over their location data. We have implemented a prototype of PDVLoc and evaluated it using real location-sharing social networking applications, Google Latitude and Foursquare. Our user study of 19 participants over 20 days shows that most users find that PDVLoc is useful to manage and control their location data, and are willing to continue using PDVLoc. <s> BIB003 </s> Tools for Achieving Usable Ex Post Transparency: A Survey <s> 3) WEB-BASED SERVICE <s> We present a prototype of the user interface of a transparency tool that displays an overview of a user's data disclosures to different online service providers and allows them to access data collected about them stored at the services' sides. We explore one particular type of visualization method consisting of tracing lines that connect a user's disclosed personal attributes to the service to which these attributes have been disclosed. We report on the ongoing iterative process of design of such visualization, the challenges encountered and the possibilities for future improvements. <s> BIB004 </s> Tools for Achieving Usable Ex Post Transparency: A Survey <s> 3) WEB-BASED SERVICE <s> The ubiquitous availability of location data to smartphone apps and online social networks has caused the collection of such information to grow at an unprecedented rate. However, the discriminative power and potential uses of this data collection is not always clear to the end user. In this work, we present FindYou, a web-based application that gives users the ability to perform a location data privacy audit. FindYou lets users import and visualize the location data collected by popular web services in order to understand what these companies know or can easily infer about them. Additionally, FindYou gives users the option to donate their data to the scientific community, creating new mobile datasets linked to user properties that will be open to use by academic institutions. We hope that FindYou will increase awareness of the privacy issues surrounding the collection and use of location data, the potential problem of "digital red-lining", and also create valuable new datasets with the full informed consent of interested users. <s> BIB005
The term 'web-based service' comprises a plethora of rich Internet applications (RIA). While applications designed for specific architectures or platforms can run only on the operating systems and run-time environments they have been designed for, RIAs can be run and interacted with by means of a standard web browser. Since both access to the Internet as well as demands for collaborative services have been BIB001 https://myaccount.google.com/intro/privacy VOLUME 5, 2017 growing, RIAs remain a stable competitor to platformspecific apps, especially if the RIA manages to incorporate the particular usage paradigms of both traditional computers and handheld devices. Many reviewed TETs used generic web services as a convenient means to configure user preferences and to audit disclosed data  ,  ,  , BIB003 , BIB005 . They act as webbased front-ends for a server-sided business logic residing in the back-end. The 'online interactive tool' presented by Kani-Zabihi et al. BIB002 runs entirely on a remote web server. The TETs presented by BIB004 ,  ,  ,  ,  are implemented as RIAs that either run as stand-alone browser apps or as front-ends that communicate with remote services.
