Abstract [en]

Public cloud providers process data on behalf of their customers in data centres that typically are physically remote from their users. This context creates a number of challenges related to data privacy and security, and may hinder the adoption of cloud technology. One of these challenges is how to maintain transparency of the processes and procedures while at the same time providing services that are secure and cost effective. This chapter presents results from an empirical study in which the cloud customers identified a number of transparency requirements to the adoption of cloud providers. We have compared our results with previous studies, and have found that in general, customers are in synchrony with research criteria for cloud service provider transparency, but there are also some extra pieces of information that customers are looking for. We further explain how A4Cloud tools contribute to addressing the customers’ requirements.

Designing for Usable Privacy and Transparency in Digital Transactions : Exploring and enhancing the usability and user experience aspects of selected privacy and transparency technologies
Abstract [en]

People engage with multiple online services and carry out a range of different digital transactions with these services. Registering an account, sharing content in social networks, or requesting products or services online are a few examples of such digital transactions. With every transaction, people take decisions and make disclosures of personal data. Despite the possible benefits of collecting data about a person or a group of people, massive collection and aggregation of personal data carries a series of privacy and security implications which can ultimately result in a threat to people's dignity, their finances, and many other aspects of their lives. For this reason, privacy and transparency enhancing technologies are being developed to help people protect their privacy and personal data online. However, some of these technologies are usually hard to understand, difficult to use, and get in the way of people's momentary goals.

The objective of this thesis is to explore, and iteratively improve, the usability and user experience provided by novel privacy and transparency technologies. To this end, it compiles a series of case studies that address identified issues of usable privacy and transparency at four stages of a digital transaction, namely the information, agreement, fulfilment and after-sales stages. These studies contribute with a better understanding of the human-factors and design requirements that are necessary for creating user-friendly tools that can help people to protect their privacy and to control their personal information on the Internet.

Abstract [en]

This paper elaborates HCI (Human-Computer Interaction) requirementsfor making cloud data protection tools comprehensible and trustworthy.The requirements and corresponding user interface design principles are derivedfrom our research and review work conducted to address in particular the followingHCI challenges: How can the users be guided to better comprehend theflow and traces of data on the Internet and in the cloud? How can individual endusers be supported to do better informed decisions on how their data can be usedby cloud providers or others? How can the legal privacy principle of transparencyand accountability be enforced by the user interfaces of cloud inspectiontools? How can the user interfaces help users to reassess their trust/distrust inservices? The research methods that we have used comprise stakeholderworkshops, focus groups, controlled experiments, usability tests as well as literatureand law reviews. The derived requirements and principles are groupedinto the following functional categories: (1) ex-ante transparency, (2) exercisingdata subject rights, (3) obtaining consent, (4) privacy preference management,(5) privacy policy management, (6) ex-post transparency, (7) audit configuration,(8) access control management, and (9) privacy risk assessment. This broadcategorization makes our results accessible and applicable for any developerwithin the field of usable privacy and transparency-enhancing technologies forcloud service chains.

Abstract [en]

Cloud computing is becoming a key IT infrastructure technology being adopted progressively by companies and users. Still, there are issues and uncertainties surrounding its adoption, such as security and how users data is dealt with that require attention from developers, researchers, providers and users. The A4Cloud project tries to help solving the problem of accountability in the cloud by providing tools that support the process of achieving accountability. This paper presents the contents of the first A4Cloud tutorial. These contents include basic concepts and tools developed within the project. In particular, we will review how metrics can aid the accountability process and some of the tools that the A4Cloud project will produce such as the Data Track Tool (DTT) and the Cloud Offering Advisory Tool (COAT).

Abstract [en]

We explore how concepts from the field of network science can be employed to inform Internet users about the way their personal identifiable information (PII) is being used and shared by online services. We argue that presenting users with graphical interfaces that display information about the network structures that are formed by PII exchanges can have an impact on the decisions users take online, such as the services they choose to interact with and the information they decide release.

Abstract [en]

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.

Abstract [en]

Transparency is a basic privacy principle and factor of social trust. However, the processing of personal data along a cloud chain is often rather intransparent to the data subjects concerned. Transparency Enhancing Tools (TETs) can help users in deciding on, tracking and controlling their data in the cloud. However, TETs for enhancing privacy also have to be designed to be both privacy-preserving and usable. In this paper, we provide requirements for usable TETs for the cloud. The requirements presented in this paper were derived in two ways; at a stakeholder workshop and through a legal analysis. Here we discuss design principles for usable privacy policies and give examples of TETs which enable end users to track their personal data. We are developing them using both privacy and usability as design criteria.

Abstract [en]

We investigate the end users’ behaviours and attitudes with regards to the control they place in the personal information that they disclose to cloud storage services. Three controlled experiments were carried out to study the influence in users’ decisions to retain or surrender control over their personal information depending on different factors. The results of these experiments reveal, among other things, the users’ willingness to surrender control over personal information that is perceived as non-sensitive in exchange for valuable rewards, and that users would value the possibility of knowing and controlling the parties who are granted access to their data in the cloud. Based on the results from the experiments we provide implications for the design of end-user tools that can promote transparency and accountability in cloud computing environments.
