Here are some pointers... 


My research is on Computational Privacy: protecting (privacy and/or commercially) sensitive data using cryptographic tools.   
I am also conducting active research on blockchain: fundamental research around consensus algorithms, leadership selection, cryptographic building blocks and smart contracts.

  • Computational Privacy (Processing Sensitive Data)
    • Privacy-aware Trusted Healthcare-COMMIT Project
    • Secure Online Social Networks-STW Project
    • Secure Recommender Systems-STW Project
    • Secure Clustering Algorithms-EU Project
    • Privacy-preserving data aggregation in e.g. Smart Grids
  • Distributed Trust-Blockchain
  • Cloud computing: integrity and verifiability, and data privacy 
  • Anonymization Techniques for Open Data 
  • Emotion Maps for Crowd Management-COMMIT Project

Dr. Z. Erkin is an associate professor in the Cyber Security Group, Delft University of Technology. He received his PhD degree on “Secure Signal Processing” in 2010 from Delft University of Technology where he has continued his research on Privacy Enhancing Technologies, particularly on Computational Privacy.  
His interest is on protecting sensitive data from malicious entities and service providers using cryptographic tools. While his interest on solutions based on provably secure cryptographic protocols is the core of his research, Dr. Erkin is also investigating distributed trust for building such protocols without trusted entities.  

Dr. Erkin has been involved in several European and national projects one of which is on Blockchain and Logistics Innovations where an unbounded scalable blockchain version with confidentiality is being developed.  He is serving also in numerous committees including IEEE Information Forensics and Security Technical Committee as chair and Editor in Chief for the Eurasip Journal on Information Security. Dr. Erkin is a member of TU Delft Blockchain Lab, also serving as a core member of Cyber Security Next Generation ( CSng), a community of cyber security researchers in the Netherlands and ICT Next Generation ( ICTng). Dr. Erkin is a Senior IEEE, ACM and IACR member.
