Master's Thesis Project: Mobile and WebView-based Fingerprinting in iOS and Android Apps

FAU Erlangen-Nuremberg
For my master's thesis I developed a comprehensive system encompassing backend, frontend, and mobile applications to investigate and evaluate fingerprinting and evaluate fingerprinting techniques.

Responsibilities and Achievements:
  • Backend Development and Deployment: Developed a backend system using NodeJS and TypeScript with PostgreSQL as the database. Configured a GitLab CI/CD pipeline to build Docker images of the backend and push them to the Docker registry. Set up a Nginx server and deployed the backend on a university server.
