Title:  Computing with private data: Data Processing in the Encrypted Domain
Time: 14:30
Location: Meeting Room B, Building Zeta
Type: Research talk
Speaker:  Riccardo Lazzeretti
Processing and encryption of content are generally considered sequential and independent operations. In certain multimedia content processing scenarios, it is, however, desirable to carry out processing directly on encrypted data to preserve the privacy of the data owners. The field of secure signal processing poses significant challenges for both signal processing and cryptography research, and only few ready-to-go fully integrated solutions are available. This talk first concisely summarizes some of the cryptographic primitives used in existing solutions to processing of encrypted signals, and discusses implications of the security requirements on these solutions. The talk then focuses on some application domains in which secure data processing has been taken up as a challenge, namely, analysis of biomedical data, remote biometric recognition and privacy-preserving IoT device coordination. Finally, the talk discusses the challenges and open issues in the field of secure data processing and other research directions recently explored at University of Padua and Sapienza University of Rome.
Short bio:
Riccardo Lazzeretti got the MSc degree (Laurea) in Computer Science Engineering and the Europeaus Ph.D. at the Information Engineering Department of the University of Siena, and during Ph.D. he spent six months in Philips Lab at Eindhoven, The Netherland. He has been a psot-doc researcher at University of Siena until 2015. From 2016 to February 2017 he has been post-doc researcher at the University of Padua, Italy, Department of Mathematics, where he was part of the SPRITZ research group. Riccardo Lazzeretti is currently assistant professor (RTD-A) at Sapienza University of Rome, Italy. He is member of CINI’s Cybersecurity National Laboratory and the Research Center of Cyber Intelligence and Information Security (CIS). His research activities span on the security field, with particular focus on privacy preserving applications based on Homomorphic Encryption and Secure Multi-Party Computation. He is associate editor of Elsevier Journal of Information Security and Applications, regularly serves in the technical program committees of conferences in the field of security. He has been deeply involved in the activities of EU and Italian funded projects in the area of security and privacy.
