Usable privacy for digital transactions : Exploring the usability aspects of three privacy enhancing mechanisms
2012
Licentiatavhandling (övrigt vetenskapligt/konstnärligt) abstract
The amount of personal identifiable information that people distribute over different online services has grown rapidly and considerably over the last decades. This has led to increased probabilities for identity theft, profiling and linkability attacks, which can in turn not only result in a threat to people’s personal dignity, finances, and many other aspects of their lives, but also to societies in general. Methods and tools for securing people’s online activities and protecting their privacy on the Internet, so called Privacy Enhancing Technologies (PETs), are being designed and developed. However, these technologies are often seen by ordinary users as complicated and disruptive of their primary tasks. In this licentiate thesis, I investigate the usability aspects of three main privacy and security enhancing mechanisms. These mechanisms have the goal of helping and encouraging users to protect their privacy on the Internet as they engage in some of the steps necessary to complete a digital transaction. The three mechanisms, which have been investigated within the scope of different research projects, comprise of (1) graphical visualizations of service providers’ privacy policies and user-friendly management and matching of users’ privacy preferences “on the fly”, (2) methods for helping users create appropriate mental models of the data minimization property of anonymous credentials, and (3) employing touch-screen biometrics as a method to authenticate users into mobile devices and verify their identities during a digital transaction. Results from these investigations suggest that these mechanisms can make digital transactions privacy-friendly and secure while at the same time delivering convenience and usability for ordinary users.

Secure and privacy-preserving identity and access management in CREDENTIAL
2019
Ingår i: Challenges in Cybersecurity and Privacy. - Delft : River Publishers. - 9788770220880 - 9788770220873 ; , s. 271-284
Bokkapitel (refereegranskat) abstract
In an increasingly interconnected world, establishing trust between endusers and service providers with regards to privacy and data protectionis becoming increasingly important. Consequently, CREDENTIAL, fundedunder the European Union’s H2020 framework programme, was dedicated tothe development of a cloud-based service for identity provisioning and datasharing. The system aimed at offering both high confidentiality and privacyguarantees to the data owner, and high authenticity guarantees to the receiver. This was achieved by integrating advanced cryptographic mechanisms intostandardized authentication protocols. The developed solutions were testedin pilots from three critical sectors, which proved that high user convenience,strong security, and practical efficiency can be achieved at the same timethrough a single system.

Defining the 'D' in ICT4D: Graduate Papers on Development, Globalisation, and ICT
2009
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt) abstract
IPID – the International Network for Postgraduate students in ICT4D – arranged a course in the academic year 2008/2009 as a response to several requests from IPID members for an introduction to development theories and for guidance in how to define the ‘D’ in the expression ICT4D. The aim of the course “Development, Globalisation and ICT (Defining the ’D’ in ICT4D) – 7.5 ECTS” was thus to provide a sound foundation for advanced studies in ICT4D. The course was designed to provide insights into some of the most influential development theories. The selection was made on the basis of classical bodies of ideas with strong impact on recent notions of development. Devoted scholars from relevant fields were invited to lecture and comment on student papers. Postgraduate students from all over the world registered for the course. Video recording was used to provide access to the lectures for those who could not attend. In the event we have eleven completed papers, which are presented in this report.

Trust in PRIME
2005
Ingår i: Proceedings of the 5<sup>th </sup>IEEE International Symposium on Signal Processing and IT. - : IEEE conference proceedings. - 0780393139 ; , s. 552-559
Konferensbidrag (övrigt vetenskapligt/konstnärligt) abstract
The PRIME project develops privacy enhancing identity management systems that allow users in various application areas such as e-commerce to regain control over their personal spheres. This paper introduces the PRIME technical architecture that also includes special trust-enhancing mechanisms, and shows how PRIME technologies can enhance privacy and trust of e-shopping customers. It also discusses the socio-psychological factors and HCI aspects influencing the end user's trust in privacy enhancing identity management, and shows why HCI research, user studies, and socio-psychological research, are necessary efforts to accompany system design.

Evaluation of early prototypes (D[6-12].1.a) : Public EU6FP IST deliverable
2004
Rapport (refereegranskat) abstract
This document captures the results of the evaluation and analysis of these early prototypes and user interface mock-ups. The evaluation is done with reference to the legal, social, economic and application requirements documented in D1.1a. Besides, usability testing is performed to evaluate mock-ups and early prototypes from an HCI perspective. This evaluation should guide the future technical development and provide input to the selection of application scenarios for which application prototypes will be developed

Usable privacy-enhancing Identity Management : Challenges and Approaches
2010
Ingår i: Information and Communication Technologies, Society and Human Beings. - Hershey PA : IGI Global. - 9781609600570 ; , s. 172-189
Bokkapitel (refereegranskat) abstract
A critical success factor for Privacy-Enhancing Technologies (PETs), and for Privacy-Enhancing Identity Management in particular, will be user-friendly and intelligible user interfaces that are legally compliant and convey trust. Such user interfaces have to meet challenges such as the user-friendly representation of complex PET concepts (such as “pseudonyms”, “unlinkabilty” or “anonymous credentials”) that are unfamiliar to many users, the provision of security, the enforcement of legal privacy principles, such as informed consent or transparency, as well as the mediation of reliable trust to the end users. In this paper, we will discuss such challenges for usable privacy-enhancing identity management and will provide some HCI guidelines for addressing those challenges.
