  Smartphone apps that run on Android devices can access many types of personal information. Such information can be used to identify, profile and track the device users when mapped into digital identity attributes. This article presents a model of identifiability through access to personal data protected by the Android access control mechanism called permissions. We present an abstraction of partial identity attributes related to such personal data, and then show how apps accumulate such attributes in a longitudinal study that was carried out over several months. We found that apps' successive access to permissions accumulates such identity attributes, where different apps show different interest in such attributes.

  Future e-identity services will need to be accessible for people with different types of abilities. We review current sets of accessibility guidelines and standards, current assistive technology, and current e-identity technology to determine accessibility and inclusion requirements for a future e-identity solution. For our project, we found that the area we could influence the most was the development of user interface for the client for e-identity and focused on these areas with the assumption that users would have access to inclusive cards and card readers. The requirements are divided into content and presentation, control and operation, legal requirements, testing, and help and support. We also provide possible areas for future research.

  Model-based risk analysis methods use graphical models to facilitate participation, risk communication and documentation and thereby improve the risk analysis process. Currently, risk analysis methods for identity management systems (IDMSs) mainly rely on time consuming and expensive manual inspections and lack graphical models. This article introduces the executable model-based risk analysis method (EM-BRAM) with the aim of addressing these challenges. The EM-BRAM employs graphical models to enhance risk analysis in IDMSs. It identifies risk contributing factors for IDMSs and uses them as inputs to a colored petri nets (CPNs) model of a targeted IDMS. It then verifies the system’s risk using CPNs’ state space analysis and queries.

  Currently, risk assessment methods for identity management systems (IDMSs) are lacking. This makes it difficult to compare IDMSs based on how they enhance privacy and security of system stakeholders. This article proposes the executable model-based risk assessment method (EM-BRAM) with the aim of addressing this challenge. The EM-BRAM identifies risk factors inherent in IDMSs and uses them as inputs to a colored petri nets (CPNs) model of a targeted IDMS. It then estimates or verifies the system’s security and privacy risks using CPNs’ state space analysis and queries.

  We describe a prototype for inclusive and secure identity management regarding a bill sharing application in social media. Beginning with the principals of universal design, and involving groups of users with impairments, we designed a set of alternative authentication methods based on OpenID. This work explains the scenario and the particularities of designing a trust, security, and privacy infrastructure with a high degree of usability for diverse user groups, and which is aligned with the requirements from regulatory frameworks. The user trials show that several authentication alternatives in multiple modalities are welcomed by impaired users, but many have restrictions when it comes to payments in the context of social media.

  Users in the Internet of Things (IoT) use strategies to determine if they should trust a system or service. These strategies are not actively declared, but it can be useful to know which strategy is being used. We provide possible actions that users may perform when using different trust strategies and possible ways these can be captured for user studies.

  End-users on the Internet of Things (IoT) will encounter many different devices and services; they will need to decide whether or not they can trust these devices and services with their information. We identify three items of trust information that end-users will need to determine if they should trust something on the IoT. We create a taxonomy of the likely scenarios end-users will encounter on the IoT and present five trust strategies for obtaining this trust information. Upon applying these strategies to our scenarios, we find that there is no strategy that can work efficiently and effectively in every situations; end-users will need to apply the strategy that best fits their current situation. Offering multiple trust strategies in parallel and having this information transparent to end-users will ensure a sustainable IoT.

  Abstract: We present a novel approach for password/credential storage in Pseudo-SSO scenarios based on a hybrid password hashing/password syncing approach that is directly applicable to the contemporary Web. The approach supports passwords without requiring modification of the server side and thus is immediately useful; however, it may still prove useful for storing more advanced credentials in future SSO and identity management scenarios, and offers a high level of security.

  This chapter documents the experiences of assurance evaluation during the early stage of a large software development project. The PRIME project researches, contracts and integrates privacy-respecting software to business environments. There exist several approaches to ensure the quality of secure software. Some of these approaches have the focus of quality assurance at a very early stage of the development process and have weaknesses to ensure the quality of this process until the product is ready to enter the market. Other approaches, like the CC, focus on inspection, or more concrete evaluation, of ready-to-market products.

  The article argues for a shift of perspective in identity management (IDM) research and development. Accessibility and usability issues affect identity management to such an extent that they demand a reframing and reformulation of basic designs and requirements of modern identity management systems. The rationale for the traditional design of identity management systems and mechanisms has been security concerns as defined in the field of security engineering. By default the highest security level has been recommended and implemented, often without taking end-user needs and accessibility issues into serious consideration. The article provides a conceptual framework for inclusive IDM, a brief overview of the regulatory status of inclusive IDM and a taxonomy of inclusive identity management methods. Several widespread IDM approaches, methods and techniques are analyzed and discussed from the perspective of inclusive design. Several important challenges are identified and some ideas for solutions addressing the challenges are proposed and discussed.

  Data protection legislation was originally defined for a context where personal information is mostly stored on centralized servers with limited connectivity and openness to 3rd party access. Currently, servers are connected to the Internet, where a large amount of personal information is continuously being exchanged as part of application transactions. This is very different from the original context of data protection regulation. Even though there are rather strict data protection laws in an increasing number of countries, it is in practice rather challenging to ensure an adequate protection for personal data that is communicated on-line. The enforcement of privacy legislation and policies therefore might require a technological basis, which is integrated with adequate amendments to the legal framework. This article describes a new approach called Privacy Policy Referencing, and outlines the technical and the complementary legal framework that needs to be established to support it.

  The popularity of the Android OS has led to the development of millions of applications. The assumption of the majority of the Android user base is that these applications are trustworthy and that the Android system does enough to protect them from the untrustworthy applications. This assumption is however false as the Android system does allow trustworthy applications to track users in different ways and does nothing to detect and remove untrustworthy applications. This project aims at informing users about which of their installed applications is tracking them and all of the negative effects it can have on a persona that is similar to them. This is done through an application that uses a pre-filled log containing the data collection of different applications to match an application with negative effects on a specific predefined persona.

  This article speculates on the future of privacy and electronic identities on the Internet. Based on a short review of security models and the development of privacy-enhancing technology, privacy and electronic identities will be discussed as parts of a larger context—an ecosystem of personal information and electronic identities. The article argues for an ecosystem view of personal information and electronic identities, as both personal information and identity information are basic required input for many applications. Therefore, for both application owners and users, a functioning ecosystem of personal information and electronic identification is important. For the future of the Internet, high-quality information and controlled circulation of such information is therefore argued as decisive for the value of future Internet applications.

  The PETweb II project has turned out to be a truly multidisciplinary project. Although the project participants have had most of their training in either law or computer science, some of the most significant results from the project is a consequence of combining ideas from economics, psychology, decision science, journalism and computer science. We believe that this project is an excellent example of how a multidisciplinary perspective can benefit research. From economics, we have imported ideas regarding utility theory. Psychology has contributed with theories of incentives and motivation. Decision science has contributed with multi- attribute utility theory. The concept of framing, belonging to the field of journalism/rhetoric has provided inspiration to explore a new way of framing risk. Computer science has offered inspiration on how the risk management and analysis concepts can be modelled and how the ideas can be implemented as a software tool. Classical risk frame focuses on incident expected impact, i.e. a combination (product) of consequence and likelihood, possibly conditioned on knowledge. PETweb II developed two alternative approaches to risk analysis – the EM-BRAM and the CIRA method. EM-BRAM starts with a model of technical risk sources in identity management technology. From there, it aims at a modelling approach of a given system into an executable model that is used to detect the presence of the risk factors in a concrete system. The risk framing proposed in the CIRA method frames risk as the underlying cause of the incident. In this frame, risk corresponds to misaligned incentives. A preliminary – bleeding edge- alpha version of a CIRA tool was developed right at the end of the project. We intend to explore the possibility of deploying CIRA and associated software tools into the data cloud. It should be kept in mind that CIRA is still in its early days, and much more research need to be completed to enhance and validate the method. However, we have already established a new project to further develop CIRA. In addition, we are planning several new projects to further explore research into a multidisciplinary perspective on risk analysis.

• Paintsil, Ebenezer; Fritsch, Lothar & Snekkenes, Einar (2013). Privacy and Security Risks Analysis of Identity Management Systems. Doctoral Dissertations at Gjøvik University College. 1-2013. Show summary

  This thesis develops a risk model and model-based risk analysis method for privacy and security risks analysis of identity management systems (IDMSs) in order to reduce cost and provide scientific support for the choice of identity management approaches. In order to analyze a system, we need a clear understanding of the system as well as what can go wrong in it. Risk assessors often rely on system specifications and stakeholders (end-users and system owners) to understand a targeted system. Similarly, system stakeholders may rely on risk assessors to understand the risk analysis process. Model-based risk analysis methods use graphical models to assist system stakeholders to understand the risk analysis process. The graphical risk models communicate what can go wrong in a system and assist in the security risk analysis. They facilitate participation, risk communication and documentation. However, current model-based risk analysis methods provide general support for security risk analysis but pay little attention to privacy. Privacy requirements complement that of security but conflicts can arise in their implementation. Identifying and understanding such conflicts are a prerequisite for developing adequate and a balanced risk analysis method. Furthermore, due to lack of data on past events, model-based risk analysis methods either rely on subjective intuitions of risk assessors and system stakeholders, or complex mathematical validation techniques to determine a system’s risk. Subjective intuitions lead to high uncertainties in risk analysis. Moreover, complex mathematical risk modeling and validation techniques are expensive, difficult to learn and can impede risk communication among system stakeholders. This thesis develops a balanced approach to risk analysis where systems’ characteristics and tools that are relatively easy to learn are relied upon to analyze privacy and security risks in IDMSs. It provides new knowledge on how to develop a privacy and security risks model for IDMSs from the characteristics of information that flow in them. Furthermore, it develops an executable model-based risk analysis method (EM-BRAM) to improve risk communication, automation, participation as well as documentation in IDMSs. The EM-BRAM relies on system behaviors or characteristics rather than data on past events or intuitions of a risk assessor to analyze privacy and security risks in IDMSs. Consequently, the method can reduce subjectivity and uncertainty in risk analysis of IDMSs. EM-BRAM identifies risk factors inherent in IDMSs and uses them as inputs for the privacy and security risks analysis. The risk factors are categorized into external and internal misuse cases. The external misuse cases consist of risk factors that may be outside the control of IDMSs while the opposite is true for internal misuse cases. The internal misuse cases are used for the privacy and security risks analysis. In order to determine a system’s risk, the EM-BRAM uses Colored Petri Nets tools and queries to model and analyze the characteristics of information flow in the target IDMS. The method has been applied to analyze the security and privacy risks of popular IDMSs such as OpenID and SAML single sign-on services for Google Apps. The results show that the EM-BRAM is effective in analyzing privacy and security of IDMSs if it is applied to low level system specifications.

  The Internet of Things (IoT) is a complex mesh‐up of devices, infrastructures and services. When connecting to a particular peer, users expose themselves to these infrastructures. This report reviews techniques and knowledge concerning the communication of status information about privacy and information security and trustworthiness to users of the IoT. Particular challenges are the complexity and instability of the infrastructures, the miniature user interfaces of smart things, and the arbitrariness and traceability of connections and device federations.

  Abstract. The FutureID project builds a comprehensive, flexible, privacy-aware and ubiquitously usable identity management infrastructure for Europe, which integrates existing eID technology and trust infrastructures, emerging federated identity management services and modern credential technologies to provide a user-centric system for the trustworthy and accountable management of identity claims. The FutureID infrastructure will provide great benefits to all stakeholders involved in the eID value chain. Users will benefit from the availability of a ubiquitously usable open source eID client that is capable of running on arbitrary desktop PCs, tablets and modern smart phones. FutureID will allow application and service providers to easily integrate their existing services with the FutureID infrastructure, providing them with the benefits from the strong security offered by eIDs without requiring them to make substantial investments. This will enable service providers to offer this technology to users as an alternative to username/password based systems, providing them with a choice for a more trustworthy, usable and innovative technology. For existing and emerging trust service providers and card issuers FutureID will provide an integrative framework, which eases using their authentication and signature related products across Europe and beyond. To demonstrate the applicability of the developed technologies and the feasibility of the overall approach FutureID will develop two pilot applications and is open for additional application services who want to use the innovative FutureID technology. This paper provides a short overview of the FutureID project. Keywords. Identity Management, eID, Identity Broker, Open Source Client

  We present scenarios in the three domains of smart home, smart office, and e-voting. The smart home consists of five scenarios; the smart office includes nine scenarios; e-voting has five scenarios. These scenarios cover a variety of situations that people may encounter in their everyday life and help to illustrate the trust issues that can show up when working with the Internet of Things (IoT). The scenarios form a foundation for many of the tasks and activities in the other work packages since the scenarios capture the functionality that we will work on. We also include a list of potential devices that may be used to realize these scenarios.
