In this seminar we want to work with you on very current topics in secure identity research that are all connected to our individual research topics. Specifically, we will present topics in the fields of:

  • Behavioral Authentication
  • Fingerprinting in P2P Networks
  • Self-Sovereign Identity Ecosystem

Depending on the topics you will be divided into groups to work on these topics and finally write a scientific report summarizing your results.

For more information on the provided topics please refer to the topic presentation slides.

Additionally, in the literature section you can find some examples of our previous publications in the context of the proposed topics.


Bitcoin P2P Network

Gotta Catch’em All! Improving P2P Network Crawling Strategies

Characterising Proxy Usage in the Bitcoin Peer-to-Peer Network


Behavorial Authentication

Beware of SMOMBIES: Verification of Users based on Activities while Walking

Under Pressure: Pushing Down on Me: Touch Sensitive Door Handle to Identify Users at Room Entry

Verification of Keyboard Acoustics Authentication on Laptops and Smartphones Using WebRTC


Self-Sovereing Identity Ecosystem

A Survey on Essential Components of a Self-Sovereign Identity

On the Relevance of Blockchain in Identity Management

A Quantifiable Trust Model for Blockchain-based Identity Management

A Comparative Analysis of Trust Requirements in Decentralized Identity Management


The following disciplines will be considered for the overall grade:

  • intermediate presentation (15%)
  • final presentation (25%)
  • source code (30%)
  • project documentation (20%)
  • student activity (10%)


Our kick-off meeting was in HS3 on 5th of November at 15:30, please refer to the recording for any questions regarding the topics.

Please also sign up to the Moodle of our course for further coordination and information. In case you want to take part make sure that you choose a topic using moodle until the 8th of November, eob.
