Abstract [en]

Log audits are the technical means to retrospectively reconstruct and analyze system activities for determining if the system events are in accordance with the rules. In the case of privacy compliance, compliance by detection approaches are promoted for achieving data protection obligations such as accountability and transparency. However significant challenges remain to fulfill privacy requirements through these approaches. This paper presents a systematic literature review that reveals the theoretical foundations of the state-of-art detective approaches for privacy compliance. We developed a taxonomy based on the technical design describing the contextual relationships of the existing solutions. The technical designs of the existing privacy detection solutions are primarily classified into privacy misuse detection and privacy anomaly detection. However, the design principles of these solutions are, to validate need-to-know and access control obligations hence the state-of-art privacy compliance validation mechanisms focus on usage limitations and accountability. The privacy compliance guarantee they provide is subtle when compared to the requirements arising from privacy regulations and data protection obligations.

The school has a two-phase review process for submitted papers. In the first phase submitted papers (short versions) are reviewed and selected for presentation at the school. After the school, these papers can be revised (so that they can benefit from the discussion that occurred at the school) and are then reviewed again for inclusion in the school’s proceedings which will be published by Springer.

Abstract [en]

This thesis deals with the evidence that enable accountability, the privacy risks involved in using them and a privacy-aware solution to the problem of unauthorized evidence disclosure. 

Legal means to protect privacy of an individual is anchored on the data protection perspective i.e., on the responsible collection and use of personal data. Accountability plays a crucial role in such legal privacy frameworks for assuring an individual’s privacy. In the European context, accountability principle is pervasive in the measures that are mandated by the General Data Protection Regulation. In general, these measures are technically achieved through automated privacy audits. System traces that record the system activities are the essential inputs to those automated audits. Nevertheless, the traces that enable accountability are themselves subject to privacy risks, because in most cases, they inform about processing of the personal data. Therefore, ensuring the privacy of the accountability traces is equally important as ensuring the privacy of the personal data. However, by and large, research involving accountability traces is concerned with storage, interoperability and analytics challenges rather than on the privacy implications involved in processing them.

This dissertation focuses on both the application of accountability evidence such as in the automated privacy audits and the privacy aware use of them. The overall aim of the thesis is to provide a conceptual understanding of the privacy compliance research domain and to contribute to the solutions that promote privacy-aware use of the traces that enable accountability. To address the first part of the objective, a systematic study of existing body of knowledge on automated privacy compliance is conducted. As a result, the state-of-the-art is conceptualized as taxonomies. The second part of the objective is accomplished through two results; first, a systematic understanding of the privacy challenges involved in processing of the system traces is obtained, second, a model for privacy aware access restrictions are proposed and formalized in order to prevent illegitimate access to the system traces. Access to accountability traces such as provenance are required for automatic fulfillment of accountability obligations, but they themselves contain personally identifiable information, hence in this thesis we provide a solution to prevent unauthorized access to the provenance traces.

Abstract [en]

This thesis deals with the evidence that enables accountability, the privacy risks involved in using it and proposes a privacy-aware solution for preventing unauthorized evidence disclosure.

Accountability plays a crucial role in the legal privacy frameworks for assuring individuals’ privacy.  In the European context, accountability principle is pervasive in the measures that are mandated by the General Data Protection Regulation. In general, these measures are technically achieved through automated privacy audits. Traces that record the system activities are the essential inputs to those audits. Nevertheless, such traces that enable accountability are themselves subject to privacy risks, because in most cases, they inform about the processing of the personal data. Therefore, ensuring the privacy of the traces is equally important as ensuring the privacy of the personal data. The aim of the thesis is to provide a conceptual understanding of the automated privacy compliance research and to contribute to the solutions that promote privacy-aware use of the accountability traces. This is achieved in this dissertation through a systematic study of the existing body of knowledge in automated privacy compliance, a systematic analysis of the privacy challenges involved in processing the traces and a proposal of a privacy-aware access control model for preventing illegitimate access to the traces.
