Prospects for Context Prediction Despite the Principle of Informational Self-Determination

Christian Voigtmann; Klaus David; Julia Zirfas; Hendrik Skistims; Alexander Rossnagel

Until now informational self-determination has not been examined in relation to context prediction. The right of users to decide whether or not and how they want their personal data to be used is not ensured. This paper analyses the problem by introducing the state of the art and application fields of context prediction with focus on the users’ personal data. Subsequently, informational self-determination and the problems that arise if techniques of context prediction compete with informational self determination will be presented. Finally, possible solutions for overcoming these problems will be outlined.

Legal Compatibility as a Characteristic of Sociotechnical Systems

Axel Hoffmann; Thomas Schulz; Julia Zirfas; Holger Hoffmann; Alexander Roßnagel; Jan Marco Leimeister

Legal compatibility as a characteristic of sociotechnical systems aims at the greatest possible compliance with higher-order legal goals for minimizing social risks of technical systems and extends legality, which refers to the prevention of lawlessness. The paper analyzes the criteria for legal compatibility by reviewing specifications of legally compatible systems and shows goals and resulting requirements to foster legal compatibility. These comprise the following areas: avoiding personal reference in data, ensuring information security, enabling freedom of decision, increasing transparency, ensuring traceability, and increasing usability, whereby traceability and the avoidance of personal reference pursue conflicting goals. The presentation of the goals including their dependencies, relationships, and conflicts in form of standardized requirements explains legal compatibility and summarizes the requirements necessary for the development of legally compatible systems.

Protecting Personality Rights and Legal Accountability

Michaela Schuldt; Thomas Schulz; Hendrik Skistims; Julia Zirfas

This chapter deals with legal requirements that need to be considered during the development process for UC systems. However, technology by itself does not always satisfy legal provisions, but it can be designed in such a way that it prevents effects that are legally considered to be disadvantageous. Special consideration is given to the right to informational self-determination and the fundamental right to the guarantee of the confidentiality and integrity of information technology systems. In addition, this contribution discusses the legal accountability regarding UC systems. Finally, proposals that can serve as examples for the design of these systems as well as for the development of German and European law will be presented.

Einsatz von Persönlichen Schutzanzügen mit I&K-Technik

Alexander Roßnagel; Silke Jandt; Hendrik Skistims; Julia Zirfas

Der Einsatz von Personlichen Schutzausrustungen dient dem Ziel, die Sicherheit der Einsatzkraft zu gewahrleisten. Die Integration von Sensoren kann noch eine weitere, zusatzliche Hilfestellung zur Vorbeugung von Gefahren wahrend des Einsatzes, die fur die Gesundheit der Einsatzkraft entstehen, darstellen und Effektivitat der Schutzanzuge verstarken.

Zulassungsvoraussetzungen für Persönliche Schutzausrüstungen mit I&K-Technik

Alexander Roßnagel; Silke Jandt; Hendrik Skistims; Julia Zirfas

Als erster Schritt bei der Frage, unter welchen Voraussetzungen Personliche Schutzausrustungen mit integrierter I&K-Technik eingesetzt werden konnen, ist zu klaren, ob fur Personliche Schutzausrustungen eine Pflicht zur Produktzulassung besteht. Eine solche Pflicht konnte sich hier fur die Schutzausrustung selbst, aber auch fur Teilkomponenten, die ein Medizinprodukt darstellen konnten, ergeben und musste somit von den Herstellern der Personliche Schutzausrustungen erfullt werden.
