Innovations and Applications in Privacy-Preserving Tech in the Age of Data Privacy
PS101: Introduction to Privacy-preserving Secure Data Computation & Analytics (TGS-2020504778)
Course Overview
In today's digitized world, as per the government regulations like PDPA and GDPR, data privacy is an important concern for both private and public organizations. On the one hand, companies would like to use data to improve their products, on the other hand, individuals as customers would want to protect our privacy. This kind of contradicting needs is exactly where the privacy-preserving technologies can be applied to meet. The innovations in privacy-preserving technologies ensure that different kinds of statistical analyses don’t compromise data privacy. They allow organizations and businesses to collect information about their uses without compromising the personal privacy.
This course aims to introduce participants with the basic approaches in privacy-preserving technologies and their applications in machine learning, healthcare, government data etc. Approaches like secure multiparty computation, homomorphic encryption, synthetic data, and differential privacy offer capabilities for managing input, analytical, and output privacy and promote data accessibility and use.

Course Highlights
Explore solutions and plans for privacy-preserving technologies (PP-Tech). Main aims at providing solutions to related industry, adding value to the digital economy, and promoting social adoption.
Homomorphic Encryption schemes allow computations on ciphertext, without revealing information on plaintext. We design new fully homomorphic encryption (FHE) constructions based on new mathematical tools to efficiently secure data management on the cloud. To improve the efficiency of existing FHE constructions, we develop efficient computation algorithms on encrypted data.
Multi-Party Computation (MPC) schemes enables multiple parties to collaboratively perform computation without disclosing any party's private input. We design and implement secure MPC based on FHE, speed up the MPC of particular functions in terms of rounds, improve communication and computation complexities.
Symmetrical Searchable Encryption (SSE) schemes allow ciphertext searching which enables data to be securely stored at the cloud. Our work focuses on building flexible SSE schemes for ease of configuration in the level of security, search time, storage for application in practical large databases. We design leakage-resilient provable secure frameworks to maximize query capacity and improve existing structured encryption schemes to achieve performance-balanced expressive SSE.
Course Instructors
Dr. Xianhu Lu is a research fellow in SCRiPTS of NTU an expert in Privacy protection of neural networks based on homomorphic encryption. Design homomorphic encryption schemes to support practical multiplications of fixed-point decimal vectors and non-linear functions such as sigmoid, ReLU and square. Explore efficient noise management algorithm to support homomorphic computation of large size numbers and large depth circuits without bootstrapping. Explore efficient message encoding algorithm to bridge the gap between the native data type of homomorphic encryption scheme and the target data type of applications.
He current research focuses on homomorphic encryption and post-quantum cryptography. He is one of the editors of the post-quantum study project of ISO/IEC SC27 WG2. He is the principal author of the algorithm LAC, which is currently one of the 26 second round candidates of the NIST Post-Quantum Cryptography Competition.
Topic: Technology Focus 3 - Searchable Encryption
Dr. Thong T. Nguyen received his Ph.D. from the School of Computer Science and Engineering, NTU. He completed his B.Sc degree in Computer Science from Ho Chi Minh City University of Technology.
Dr. Tong T. Nguyen research is at the intersection between differential privacy and machine learning. He contributed to the development of differentially private techniques for survival analysis models. He also proposed techniques to collect distributed data with local differential privacy.
His current research is on the applications of cryptographic techniques in training machine learning models with differential privacy guarantees.
Topic: Technology Focus 3 - Searchable Encryption
Dr. Melody research topic is local differential privacy technology (LDP). As LDP perturbs the users’ data locally before it leaves their own devices, nobody can access the original data except the data owner. It prevents single-point failures for data breaches and provides much stronger privacy protection. Therefore, it received a significant amount of attention and has been deployed by many big companies, such as Google, Apple, and Microsoft.
Her research mainly focusses on designing local differential privacy algorithm to support the statistics over the smaller population, and quantify the sample complexity. Currently, the main directions we considered are definition relaxation, privacy amplification and combination with MPC.
Topic: Technology Focus 4 - Differential Privacy and its Application
Dr. Zhao received his Ph.D. degree from the Department of Information Engineering, the Chinese University of Hong Kong.
Dr. Zhao under the supervision of Prof. Sherman S. M. Chow for his Ph.D. Before joining NTU, Dr. Zhao was a research fellow at the Chinese University of Hong Kong. He has been working on cryptographic cloud storage systems as well as private set-intersection protocols, resulting in publications in top-tier journals and conferences, e.g., IEEE Transactions on Dependable and Secure Computing (IEEE-TDSC), the International Conference on Practice and Theory in Public Key Cryptography (PKC), the annual Privacy Enhancing Technologies Symposium (PETS).
Dr. Zhao is interested in applying cryptography to privacy-enhancing technologies. He is now mainly working on symmetric searchable encryption in the Strategic Centre for Research in Privacy-Preserving Technologies & Systems, Nanyang Technological University.
