Trust in PRIME

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 users trust in privacy enhancing identity management, and shows why HCI research, user studies, and socio-psychological research, are necessary efforts to accompany system design

Exploring the Feasibility of a Spatial User Interface Paradigm for Privacy-Enhancing Technology

Electronic devices get more and more involved in many of our communication processes for personal and professional activities. Each communication process may implicitly affect our privacy. An example may be the location trace of mobile phones. Experts present identity management systems to preserve the user’s1 privacy [2]. In digital correspondence users should decide about disclosure of personally identifiable information (in the following simply called “data”). However, identity management for Everyman is not yet a commonplace.

Visualising interactive graphics design for testing with users

The Ozlab set-up used in this study is intended to facilitate performance tests at a conceptual stage in the development of interactive multimedia products. Ozlab facilitates manual simulations of the interactivity of proposed user interfaces, thereby simplifying testing and making the development of ideas during test runs possible. Even non-programmers can perform these activities. The paper reports on a pilot study within the efforts currently taking place concerning educationalists focusing on language disabilities, where the clients could benefit from graphical support in interactive teaching aids. Ozlab extends the traditional, linguistically- based Wizard-of-Oz technique for manual prototyping to graphical interaction. The pilot study indicates that a refined Ozlab could be used by inexperienced designers for testing their own ideas. The fact that requirements of interactivity thus can be visualised by laymen will have implications for the design of requirements specification for multimedia products.

Facebook usage in a local government: A content analysis of page owner posts and user posts

Purpose To fully grasp the potential of using social media, one must know what governments and citizens are communicating in these media. Despite much statistics published, there is a dearth of research analyzing information content in detail. The purpose of this paper is to identify the kind of information exchange that occurs between a local government and its constituent citizens using social media. Design/methodology/approach This paper presents a qualitative single case study of the Facebook presence of the municipality and city of Karlstad, Sweden, one of the most prominent local governments on Facebook in the country. Facebook page data were collected between May 2015 and July 2015. A content analysis was performed on the data to explore new and existing categories that drive the analysis. Findings The paper identifies 11 content categories for municipality posts and 13 content categories for user posts (citizen or organization). The frequency for each content category reveals that the page owner is first of all using its Facebook page to promote different happenings in the municipality while the page user is asking questions to the municipality or other users. Research limitations/implications The study is limited to one municipality, but achieves analytical generalizability in its findings. In other words, the categories and mode of communication are a finding in and of itself that in future research may be validated in terms of commonality on a national scale. Practical implications Management concerns about opening up a municipality Facebook page for user posting may be exaggerated: positive posts are as common as complaints. If an organization wants to use the Facebook page for increased user participation and collaboration, it seems that users, both citizens and organizations, welcome such opportunities. However, such posts are not likely to receive many comments or shares from other users. Originality/value The paper is one of the first that uses content analysis to categorize both page owner posts and user posts on a local government Facebook page. The content categories identified in the paper provide novel and detailed insights on what types of information exchange occur on social media between a local government and citizens but also highlight the need to distinguish organizations from citizens among the visitors to the government Facebook page. Different types of user will post different types of content. The identified content categories can serve as a basis for future empirical research within e-government research.

Ozlab: a simple demonstration tool for prototyping interactivity

A system for testing interaction design without the need for programming is described. This technique has the advantage of paper prototying allowing for rapid prototyping. In the same time it makes a prototype look real why it is possible to test the prototype as if it were a functioning piece of software.

A Brief Evaluation of Icons in the First Reading of the European Parliament on COM (2012) 0011

We present the result of a small-scale test in which the participants failed to understand the graphic scheme as well as the pictographic parts of the icons appearing in the Annex to Article 13a of the European Parliament legislative resolution of 12 March 2014 on the Proposal for a regulation of the European Parliament and of the Council on the protection of individuals with regard to the processing of personal data and on the free movement of such data (General Data Protection Regulation), COM (2012) 0011.

Towards the Adoption of Secure Cloud Identity Services

Enhancing trust among service providers and end-users with respect to data protection is an urgent matter in the growing information society. In response, CREDENTIAL proposes an innovative cloud-based service for storing, managing, and sharing of digital identity information and other highly critical personal data with a demonstrably higher level of security than other current solutions. CREDENTIAL enables end-to-end confidentiality and authenticity as well as improved privacy in cloud-based identity management and data sharing scenarios. In this paper, besides clarifying the vision and use cases, we focus on the adoption of CREDENTIAL. Firstly, for adoption by providers, we elaborate on the functionality of CREDENTIAL, the services implementing these functions, and the physical architecture needed to deploy such services. Secondly, we investigate factors from related research that could be used to facilitate CREDENTIALs adoption and list key benefits as convincing arguments.

HCI requirements for Transparency and Accountability Tools for Cloud Service Chains

Cloud computing represents a major shift in the way Information and Communication Technology (ICT) is deployed and utilised across industries. Alongside the technological developments, organisations need to adapt to emerging operational needs associated with data governance, policy and responsibility, as well as compliance with regulatory regimes that may be multi-jurisdictional in nature. This paper is concerned with data governance in cloud ecosystems. It characterises the problem of data governance due to emerging challenges (and threats) in the cloud. It advocates an accountability-based approach for data stewardship. It defines accountability and introduces a model consisting of attributes, practices and mechanisms. The accountability model underpins an accountability framework supporting data governance. This paper also discusses emerging relationships between accountability, risk and trust. The overall objective of the proposed accountability-based approach to data governance is to support a transparent and trustworthy cloud.

Effects of Early User-Testing on Software Quality – Experiences from a Case Study

It is a well-established fact that the usability of a software package increases if it has been tested with users and usability flaws have been corrected. However, this presentation does not focus on usability issues but on the effects of early user-testing on software code quality determined as the number of errors discovered in function tests. In analysing the results of an extensive software update cycle, the authors found that functional requirements based on the results of early user-testing resulted in program code that had half the number of the errors (and less than one-fifth of the critical errors) found in code based solely on requirements emanating from users’ verbal opinions.

Human-computer interaction

An important critical success factor for PRIME technology will be userfriendly and intelligible user interfaces that convey and enhance trust. Such user interfaces have to meet challenges such as:
