»Localization of Employees. Questions of Admissibility under Data Protection Law using the Example of Employee Tracking«: Using the example of employee tracking, the thesis deals with questions of admissibility under data protection law. It systematises - abstractly as well as concretely in relation to employee tracking - a risk-based protection concept that can lead to an appropriate balancing of the conflicting interests. The author argues in favour of differentiating more strongly on the basis of the risk that data processing poses to the protected privacy interest.
