Personal Information Markets AND Privacy: A New Model to Solve the Controversy

From the early days of the information economy, personal data has been its most valuable asset. Despite data protection laws, companies trade personal information and often intrude on the privacy of individuals. As a result, consumers feel out of control and lose trust in electronic environments. Technologists and regulators are struggling to develop solutions that meet businesses’ demand for more personal information while maintaining privacy. However, no promising proposals seem to be in sight. We propose a 3-tier personal information market model with privacy. In our model, clear roles, rights and obligations for all actors re-establish trust. The ‘relationship space’ enables data subjects and visible business partners to build trusting relationships. The ‘service space’ supports customer relationships with distributed information processing. The ‘rich information space’ enables anonymized information exchange. To transition to this model, we show how existing privacy-enhancing technologies and legal requirements can be integrated

Enhancing Information Governance with Enterprise Architecture Management: Design Principles Derived from Benefits and Barriers in the GDPR Implementation

Businesses today are increasingly dependent on how they transform information into economic value, while simultaneously being compliant with intensified privacy requirements, resulting from legal acts like the General Data Protection Regulation (GDPR). As a consequence, realizing information governance has become a topic more important than ever to balance the beneficial use and protection of information. This paper argues that enterprise architecture management (EAM) can be a key to GDPR implementation as one important domain of information governance by providing transparency on information integration throughout an organization. Based on 24 interviews with 29 enterprise architects, we identified a multiplicity of benefits and barriers within the interplay of EAM and GDPR implementation and derived seven design principles that should foster EAM to enhance information governance

Automation for network security configuration: state of the art and research trends

The size and complexity of modern computer networks are progressively increasing, as a consequence of novel architectural paradigms such as the Internet of Things and network virtualization. Consequently, a manual orchestration and configuration of network security functions is no more feasible, in an environment where cyber attacks can dramatically exploit breaches related to any minimum configuration error. A new frontier is then the introduction of automation in network security configuration, i.e., automatically designing the architecture of security services and the configurations of network security functions, such as firewalls, VPN gateways, etc. This opportunity has been enabled by modern computer networks technologies, such as virtualization. In view of these considerations, the motivations for the introduction of automation in network security configuration are first introduced, alongside with the key automation enablers. Then, the current state of the art in this context is surveyed, focusing on both the achieved improvements and the current limitations. Finally, possible future trends in the field are illustrated

Individual values of GenZ in managing their Internet Privacy: a decision analytic assessment

A nossa investigação coloca a importância dos valores individuais como o centro de qualquer discussão sobre questões de privacidade. Os valores têm um papel essencial no discurso científico. Notamos que o conceito de valores é um dos poucos discutidos e utilizados em várias disciplinas das ciências sociais. Para isso, nesta investigação, apresentamos objetivos baseados em valores para a privacidade na Internet da GenZ. Os objetivos são classificados em duas categorias - os objetivos fundamentais e os meios para os atingir. Em síntese, os nossos seis objetivos fundamentais orientam a gestão das questões de privacidade da Internet da GenZ. Os objetivos são: Aumentar a confiança nas interações online; Maximizar a responsabilidade dos detentores de dados; Maximizar o direito à privacidade; Maximizar a capacidade individual de gerir o controlo da privacidade; Maximizar a percepção da funcionalidade da plataforma; Garantir que os dados pessoais não são alterados. Coletivamente, os objetivos fundamentais e de meios são uma base valiosa para a GenZ avaliar a sua postura de privacidade. Os objetivos também são úteis para que as empresas de media social e outras plataformas relacionadas elaborem as suas políticas de privacidade de acordo com o que a GenZ deseja. Finalmente, os objetivos são uma ajuda útil para o desenvolvimento de leis e regulamentos; Individual values of GenZ in managing their Internet Privacy: a decision analytic assessment Abstract: Online privacy is a growing concern. As individuals and businesses connect, the problem of privacy continues to remain significant. In this thesis, we address three primary questions - What are the individual values of GenZ concerning online privacy? What are the fundamental objectives of GenZ in terms of protecting their online privacy? What are the means objectives GenZ consider for protecting their online privacy? We argue that online privacy for GenZ is vital to protect. We also argue that protection can be ensured if we understand and know what privacy-related values behold GenZ and define their objectives accordingly. Our research brings the importance of individual values to be central to any discussion of privacy concerns. Values have an essential place in scientific discourse. We note that the concept of values is one of the very few discussed and employed across several social science disciplines. To that effect, in this research, we present value-based objectives for GenZ internet privacy. The objectives are classified into two categories – the fundamental objectives and the means to achieve them. In a final synthesis, our six fundamental objectives guide the management of GenZ Internet Privacy Concerns. The objectives are: Increase trust in online interactions; Maximize responsibility of data custodians; Maximize right to be left alone; Maximize individual ability to manage privacy controls; Maximize awareness of platform functionality; Ensure that personal data does not change. Collectively our fundamental and means objectives are a valuable basis for GenZ to evaluate their privacy posture. The objectives are also helpful for the social media companies and other related platforms to design their privacy policies according to the way GenZ wants. Finally, the objectives are a helpful policy aid for developing laws and regulations

Adding Privacy Protection to Policy Based Authorisation Systems

An authorisation system determines who is authorised to do what i.e. it assigns privileges to users and provides a decision on whether someone is allowed to perform a requested action on a resource. A traditional authorisation decision system, which is simply called authorisation system or system in the rest of the thesis, provides the decision based on a policy which is usually written by the system administrator. Such a traditional authorisation system is not sufficient to protect privacy of personal data, since users (the data subjects) are usually given a take it or leave it choice to accept the controlling organisation’s policy. Privacy is the ability of the owners or subjects of personal data to control the flow of data about themselves, according to their own preferences. This thesis describes the design of an authorisation system that will provide privacy for personal data by including sticky authorisation policies from the issuers and data subjects, to supplement the authorisation policy of the controlling organisation. As personal data moves from controlling system to controlling system, the sticky policies travel with the data. A number of data protection laws and regulations have been formulated to protect the privacy of individuals. The rights and prohibitions provided by the law need to be enforced by the authorisation system. Hence, the designed authorisation system also includes the authorisation rules from the legislation. This thesis describes the conversion of rules from the EU Data Protection Directive into machine executable rules. Due to the nature of the legislative rules, not all of them could be converted into deterministic machine executable rules, as in several cases human intervention or human judgement is required. This is catered for by allowing the machine rules to be configurable. Since the system includes independent policies from various authorities (law, issuer, data subject and controller) conflicts may arise among the decisions provided by them. Consequently, this thesis describes a dynamic, automated conflict resolution mechanism. Different conflict resolution algorithms are chosen based on the request contexts. As the EU Data Protection Directive allows processing of personal data based on contracts, we designed and implemented a component, Contract Validation Service (ConVS) that can validate an XML based digital contract to allow processing of personal data based on a contract. The authorisation system has been implemented as a web service and the performance of the system is measured, by first deploying it in a single computer and then in a cloud server. Finally the validity of the design and implementation are tested against a number of use cases based on scenarios involving accessing medical data in a health service provider’s system and accessing personal data such as CVs and degree certificates in an employment service provider’s system. The machine computed authorisation decisions are compared to the theoretical decisions to ensure that the system returns the correct decisions

Detecting and resolving redundancies in EP3P policies

Current regulatory requirements on data privacy make it increasingly important for enterprises to be able to verify and audit their compliance with their privacy policies. Traditionally, a privacy policy is written in a natural language. Such policies inherit the potential ambiguity, inconsistency and mis-interpretation of natural text. Hence, formal languages are emerging to allow a precise specification of enforceable privacy policies that can be verified. The EP3P language is one such formal language. An EP3P privacy policy of an enterprise consists of many rules. Given the semantics of the language, there may exist some rules in the ruleset which can never be used, these rules are referred to as redundant rules. Redundancies adversely affect privacy policies in several ways. Firstly, redundant rules reduce the efficiency of operations on privacy policies. Secondly, they may misdirect the policy auditor when determining the outcome of a policy. Therefore, in order to address these deficiencies it is important to identify and resolve redundancies. This thesis introduces the concept of minimal privacy policy - a policy that is free of redundancy. The essential component for maintaining the minimality of privacy policies is to determine the effects of the rules on each other. Hence, redundancy detection and resolution frameworks are proposed. Pair-wise redundancy detection is the central concept in these frameworks and it suggests a pair-wise comparison of the rules in order to detect redundancies. In addition, the thesis introduces a policy management tool that assists policy auditors in performing several operations on an EP3P privacy policy while maintaining its minimality. Formal results comparing alternative notions of redundancy, and how this would affect the tool, are also presented

Cloud Privacy Audit Framework: A Value-Based Design

The rapid expansion of cloud technology provides enormous capacity, which allows for the collection, dissemination and re-identification of personal information. It is the cloud’s resource capabilities such as these that fuel the concern for privacy. The impetus of these concerns are not too far removed from those expressed by Mason in 1986, when he identified privacy as one of the biggest ethical issues facing the information age. There seems to be continuous ebb and flow relationship with respect to privacy concerns and the development of new information communication technologies such as cloud computing. Privacy issues are a concern to all types of stakeholders in the cloud. Individuals using the cloud are exposed to privacy threats when they are persuaded to provide personal information unwantedly. An Organization using a cloud service is at risk of non-compliance to internal privacy policies or legislative privacy regulations. The cloud service provider has a privacy risk of legal liability and credibility concerns if sensitive information is exposed. The data subject is at risk of having personal information exposed. In essence everyone who is involved in cloud computing has some level of privacy risk that needs to be evaluated before, during and after they or an organization they interact with adopts a cloud technology solution. This resonates a need for organizations to develop privacy practices that are socially responsible towards the protection of their stakeholders’ information privacy. This research is about understanding the relationship between individual values and their privacy objectives. There is a lack of clarity in organizations as to what individuals consider privacy to be. Therefore, it is essential to understand an individual’s privacy values. Individuals seem to have divergent perspectives on the nature and scope of how their personal information is to be kept private in different modes of technologies. This study is concerned with identifying individual privacy objectives for cloud computing. We argue that privacy is an elusive concept due to the evolving relationship between technology and privacy. Understanding and identifying individuals’ privacy objectives are an influential step in the process of protecting the privacy in cloud computing environments. The aim of this study is to identify individual privacy values and develop cloud privacy objectives, which can be used to design a privacy audit for cloud computing environments. We used Keeney’s (1992) value focused thinking approach to identify individual privacy values with respect to emerging cloud technologies, and to develop an understanding of how cloud privacy objectives are shaped by the individual’s privacy values. We discuss each objective and how they relate to privacy concerns in cloud computing. We also use the cloud privacy objectives in a design science study to design a cloud privacy audit framework. We then discuss the how this research helps privacy managers develop a cloud privacy strategy, evaluate cloud privacy practices and develop a cloud privacy audit to ensure privacy. Lastly, future research directions are proposed

Architektur- und Werkzeugkonzepte für föderiertes Identitäts-Management

Als essentielle Komponente des IT-Security Managements umfasst das Identity & Access Management (I&AM) saemtliche organisatorischen und technischen Prozesse der Verwaltung von Dienstnutzern einer Einrichtung und deren Berechtigungen; dabei werden die Datenbestaende verschiedenster autoritativer Datenquellen wie Personal- und Kundenverwaltungssysteme aggregiert, korreliert und in aufbereiteter Form den IT-Services zur Verfuegung gestellt. Das Federated Identity Management (FIM) hat zum Ziel, die so geschaffenen integrierten Datenbestaende auch organisationsuebergreifend nutzbar zu machen; diese Funktionalitaet wird beispielsweise im Rahmen von Business-to-Business-Kooperationen, Outsourcing-Szenarien und im Grid-Computing zunehmend dringender benoetigt. Die Vermeidung von Redundanz und Inkonsistenzen, aber auch die garantierte Verfuegbarkeit der Daten und die Einhaltung von Datenschutzbestimmungen stellen hierbei besonders kritische Erfolgsfaktoren dar. Mit der Security Assertion Markup Language (SAML), den Spezifikationen der Liberty Alliance und WS-Federation als integralem Bestandteil des Web Services WS-*-Protokollstacks haben sich industrielle und partiell standardisierte technische Ansaetze fuer FIM herauskristallisiert, deren praktische Umsetzung jedoch noch haeufig an der nur unzureichend geklaerten, komplexen organisatorischen Einbettung und den technischen Unzulaenglichkeiten hinsichtlich der Integration in bestehende IT-Infrastrukturen scheitert. In dieser Arbeit wird zunaechst eine tiefgehende und in diesem Umfang neue Anforderungsanalyse durchgefuehrt, die neben I&AM und FIM auch die als User-Centric Identity Management (UCIM) bezeichnete Benutzerperspektive beruecksichtigt; die Schwerpunkte der mehr als 60 strukturierten und gewichteten Anforderungen liegen dabei auf der Integration von I&AM- und FIM-Systemen sowohl auf der Seite der organisation, der die Benutzer angehoeren (Identity Provider), als auch beim jeweiligen Dienstleister (Service Provider), und auf dem Einbezug von organisatorischen Randbedingungen sowie ausgewaehlten Sicherheits- und Datenschutzaspekten. Im Rahmen eines umfassenden, gesamtheitlichen Architekturkonzepts wird anschliessend eine Methodik zur systematischen Integration von FIM-Komponenten in bestehende I&AM-Systeme erarbeitet. Neben der praezisen Spezifikation der technischen Systemschnittstellen, die den bestehenden Ansaetzen fehlt, fokussiert diese Arbeit auf die organisatorische Eingliederung aus Sicht des IT Service Managements, wobei insbesondere das Security Management und das Change Management nach ITIL vertieft werden. Zur Kompensation weiterer grundlegender Defizite bisheriger FIM-Ansaetze werden im Rahmen eines Werkzeugkonzepts fuenf neue FIM-Komponenten spezifiziert, die auf eine verbesserte Interoperabilitaet der FIM-Systeme der an einer so genannten Identity Federation beteiligten organisationen abzielen. Darueber hinaus wird auf Basis der eXtensible Access Control Markup Language (XACML) eine policy-basierte Privacy Management Architektur spezifiziert und integriert, die eine dezentrale Steuerung und Kontrolle von Datenfreigaben durch Administratoren und Benutzer ermoeglicht und somit essentiell zur Einhaltung von Datenschutzauflagen beitraegt. Eine Beschreibung der prototypischen Implementierung der Werkzeugkonzepte mit einer Diskussion ihrer Performanz und die methodische Anwendung des Architekturkonzepts auf ein komplexes, realistisches Szenario runden die Arbeit ab

Privacy-enabled Services for Enterprises

The IBM Enterprise Privacy Architecture (EPA) is a methodology for enterprises to provide an enhanced and well-defined level of privacy to their customers. EPA is structured in four building blocks. The privacy regulation analysis identifies and structures the applicable regulations. The management reference model enables an enterprise to define and enforce an enterprise privacy strategy and the resulting privacy practices. The privacy agreement framework is a methodology for privacy-enabling business process re-engineering. It outputs a detailed model of the privacy-relevant players and activities as well as the privacy policies that govern these activities. The technical reference architecture defines the technology needed for implementing the identified practices. The Platform for Enterprise Privacy Practices (E-P3P) is a refinement of EPAs technical reference architecture: Enterprises collect a certain amount of personal data while promising fair information practices to their customers. E-P3P enables an enterprise to keep the privacy promises made. It formalizes these privacy promises into policies and associates a consented policy to each piece of collected data. This consented policy can then be used in access control decisions to enforce the privacy promises made
