Prof. David-Olivier Jaquet-Chiffelle is full professor at the School of Criminal Justice, University of Lausanne, Switzerland, where he started teaching in 2003. He is head of the Master program in forensic science, orientation digital investigation and identification.

David-O. Jaquet-Chiffelle accomplished his PhD thesis in Mathematics at the University of Neuchâtel, Switzerland. He spent a post-doc at Harvard University (Boston, USA) where he was also lecturer in the Department of Mathematics. Then, he strengthened his experience in cryptology while working for the Swiss government at the Swiss Federal Section of Cryptology.

Projects and expertise

David-O. Jaquet-Chiffelle conceived the system used by the Swiss Federal Statistical Office (SFSO) for its official medical statistics of all patients hospitalized in Switzerland. This system allows the SFSO to recognize that the same patient was hospitalized in two different hospitals, even on different years, while protecting the patient’s anonymity. All Swiss hospitals now use this system to transfer their data to the SFSO.

Recent and current projects include the CANVAS H2020 EU project (Constructing an Alliance for Value-driven Cybersecurity, as workpackage leader) and “Creating an ethical and legal governance framework for trustworthy cybersecurity in Switzerland” (as co-PI), a Swiss Digital Transformation NRP 77 project. Moreover, David-O. Jaquet-Chiffelle is the inventor of one patent related to authentication processes, and co-inventor of two other patent applications linked to biometric pseudonyms. He regularly acts as an expert both in Switzerland and internationally, and is active in standardization bodies (NIST, ISO).

His current research covers cybercrime, ethics and cybersecurity, privacy, new forms of identities in the information society, anonymization, identification and authentication processes, especially in the digital world, as well as blockchain technologies to support authentication and integrity.
