It is a fundamental right of every natural person to control which personal information is collected, stored and processed by whom, for what purposes and how long. In fact, many (cloud based) services can only be used if the user allows them broad data collection and analysis. Often, users can only decide to either give their data or not to participate in communities. The refusal to provide personal data results in significant drawbacks for social interaction. That is why we believe that there is a need for tools to control one's own data in an easy and effective way as protection against economic interest of global companies and their cloud computing systems (as data collector from apps, mobiles and services). Especially, as nowadays everybody is permanently online using different services and devices, users are often lacking the means to effectively control the access to their private data. Therefore, we present an approach to manage and distribute privacy settings: PRIVACY-AVARE is intended to enable users to centrally determine their data protection preferences and to apply them on different devices. Thus, users gain control over their data when using cloud based services. In this paper, we present the main idea of PRIVACY-AVARE.
Applications for the Internet of Things are becoming increasingly popular. Due to the large amount of available context data, such applications can be used effectively in many domains. By interlinking these data and analyzing them, it is possible to gather a lot of knowledge about a user. Therefore, these applications pose a threat to privacy. In this paper, we illustrate this threat by looking at a real-world application scenario. Current state of the art focuses on privacy mechanisms either for Smart Things or for big data processing systems. However, our studies show that for a comprehensive privacy protection a holistic view on these applications is required. Therefore, we describe how to combine two promising privacy approaches from both categories, namely AVARE and PATRON. Evaluation results confirm the thereby achieved synergy effects.
Digital Transformation, Smart Factories, and Virtual Design: Contributions of Subject Orientation

Nachhaltigkeit ist für die Gesellschaften unseres Planeten von grundlegender Bedeutung, ebenso wie Software Systeme immer mehr Teil der heutigen Gesellschaften werden. Daher gewinnt Nachhaltigkeit auch immer mehr an Relevanz im Software Engineering und es wurden erste Ansätze entwickelt, um Nachhaltigkeit bei dem Software System Design zu berücksichtigen. Dennoch bleibt es schwer die erst später eintreffenden Auswirkungen von Entscheidungen, die beim System Design getroffen werden, zu erkennen und zu bewerten. Um diese schwierige Aufgabe zu unterstützen, wird in der Keynote die Metapher „Sustainability Debt“ vorgestellt. Die Metapher hilft bei der Identifikation, Dokumentation und Kommunikation von Nachhaltigkeitsfragen im Software Engineering. Sie baut auf der bestehenden Metapher des „Technical Debt“ auf und erweitert diese um vier weitere Dimensionen der Nachhaltigkeit (individuell, sozial, ökologisch, ökonomisch). Neben der Bedeutung der Metapher Sustainability Debt und ihrer Verwendung im Software Engineering wird im Rahmen der Keynote auch darauf eingegangen wie im Software Engineering Entscheidungen getroffen werden. Da Entscheidungen im Rahmen des Sustainability Debts immer bedeuten einen Kompromiss zu schließen zwischen zeitnahen und entfernten Ergebnissen. Bei solchen intertemporalen Entscheidungen werden entfernte Ergebnisse oft als weniger bedeutsam bewertet als zeitnahe, was berücksichtigt werden muss, um eine entsprechende Entscheidungsunterstützung zur Verringerung des Sustainability Debts zu liefern.
