SkillsFuture Series: Privacy-Preserving Technologies

PS101: Introduction to Privacy-preserving Secure Data Computation & Analytics

PROGRAMME OVERVIEW:

In the modern era of pervasive technological advancements, a huge amount of information has been collected through various channels such as personal smart devices, online surfing, or provided to companies when subscribing to their services. As a result, privacy preservation has taken a lead role in ensuring proper usage and confidentiality of data in every sector of our lives. As per the government regulations like PDPA and GDPR, privacy of data is crucial for every individual and enterprise, especially so in the context of collaborative learning within multi-enterprise federations.

Through the 2-day course, participants will be exposed to the four primary technological verticals aid in privacy-preserving data discovery, aggregation, search, mining, and data-driven learning. These technologies are Differential Privacy, Searchable Encryption, Multi-Party Computation and Homomorphic Encryption. After the completion, participants will get an understanding of how these approaches address the challenge from different angles.

TOPICS COVERED:
1: Introduction to Privacy-preserving Techniques: Background, Technology, and Use Cases

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.

2: Technology Focus 1 - Homomorphic Encryption

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.

3: Technology Focus 2 - Secure Multiparty Computation

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.

4: Technology Focus 3 - Searchable Encryption

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.

5: Technology Focus 4 - Differential Privacy and its Applications

Differential Privacy mechanism can be used to satisfy data aggregation without leaking individual private information. These algorithms rely on incorporating random noise into the data.

Dr. Lu Xianhui

Topic: Technology Focus 1 - Homomorphic Encryption

Dr. Xianhui Lu received his Ph.D. in information security from Southwest Jiaotong University in 2009.

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.

Dr. Thong T. Nguyen

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.

Dr. Mengmeng Yang (Melody)
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.
