Matthias Matousek

I have been studying Computer Sciene in Media at the University of Ulm until the summer of 2015. I also spent one year of my studies (2013-2014) in the Netherlands where I visited lectures at three different universities: University of Twente, Eindhoven University of Technology, and Radboud Unversity Nijmegen. The lectures were part of the Kerckhoffs Institute for Computer Security. For my Master's Thesis I was working on a secure processor called Secure Execution PUF-based Processor (SEPP). In summer 2015 I joined the Institute of Distributed Systems, where I am now working as a research assistant.

Research

I am generally interested in security and privacy of IT systems. Specifically, I am working on the privacy of interconnected vehicles. Furthermore, I am interested in enabling private communication (such as cryptography in messenger services) in a user-friendly way.

Abstract: Machine learning offers great opportunities, but also comes with risks. Especially the privacy risks are becoming more prevalent in the discussions about machine learning. Recently, Google published a machine learning library called TensorFlow Privacy. Its goal is to make it easier for developers and researchers to build privacy-preserving machine learning models. Specifically, it utilizes Differential Privacy, which mathematically guarantees that the training data to create the models is protected from being extracted. The goal of this thesis or project is to become familiar with the TensorFlow Privacy library, to understand and be able to explain the techniques which are implemented in it, to be able to build privacy-preserved machine learning models, and possibly to implement own protection techniques that could enhance the TensorFlow Privacy library.
