Title: Privacy Computing and its Research Scope

Abstract: With the rapid development of information technology and the continuous evolution of service mode, it leads to a common situation in which a massive amount of users’personal information interacts across information systems, digital ecosystems, and even national network boundaries. However, existing privacy-preserving schemes cannot provide systematic privacy preservation, and problems like dynamic privacy measurement and extended control, tracing the source of privacy violations are still unsolved, therefore, it is necessary to set up a completely theoretical system of privacy preservation. This report includes: definition of privacy computing, key technical links and the computing framework of privacy computing, some important characteristic, intelligent sensing and dynamical measurement of private information, algorithm design criteria, evaluation of the privacy-preserving effect, privacy computing language, determining and tracing the privacy violations, and system architecture of privacy Information. Finally, we discuss the prospect of future research trends.

Title: Artificial Intelligence and Security: Challenges, Methodologies and Future Directions

Abstract: Artificial Intelligence (AI) technologies have been developed for numerous systems and services, such as face recognition, smart health, auto-drive, smart city, etc. According to the laws and regulations in China, it is desirable to develop both security techniques for AI applications and AI-driven security techniques. On the one hand, we introduce security techniques to protect the privacy of participants when utilizing AI to make timely and safe decisions in unpredictable environments. On the other hand, we illustrate several AI-driven techniques to enhance system security. Finally, we discuss future directions of AI and Security.

Title: Towards Efficient Privacy-Preserving Inspection of TLS Encrypted Traffic

Abstract: Network middleboxes perform deep packet inspection to detect anomalies and suspicious activities in network traffic. However, increasingly these traffic are encrypted and middleboxes can no longer make sense of them. This raises the problem of privacy-preserving inspection on TLS encrypted traffic. In this talk will first introduce the need for TLS traffic inspection and the problem with the existing approach. Three recent proposals, namely Blindbox, PrivDPI and Pine, will be then introduced. Finally, I will present conclusion and future direction.

Title: How to Ensure Secure Data Sharing with Blockchain in IoT

Abstract: With the rapid development of IoT techniques, IoT networks constantly generate a large amount of data which contain valuable information for various industrial applications after collecting and analyzing. However, it is almost impossible to enable users to effectively contribute their data without privacy guarantees and incentive mechanisms. Such challenges seriously restrict the data sharing in IoT networks. To this end, based on the blockchain platform, we propose a data incentive mechanism to provide data privacy and fairness measures for users in IoT. Moreover, we give two different constructions of the proposed mechanism and analyze their performances on privacy protection and transaction efficiency.

Title: Data-Driven Security Analysis of Machine Learning Systems

Abstract: Human society is witnessing a wave of machine learning (ML) driven by deep learning techniques, bringing a technological revolution for human production and life. In some specific fields, ML has achieved or even surpassed human-level performance. However, most previous machine learning theories have not considered the open and even adversarial environments, and the security and privacy issues are gradually rising. Besides of insecure code implementations, biased models, adversarial examples, sensor spoofing can also lead to security risks, which are hard to be discovered by traditional security analysis tools. This talk reviews previous works on ML system security and privacy, revealing potential security and privacy risks. Firstly, we introduce a threat model of ML systems, including attack surfaces, attack capabilities and attack goals. Second, we analyze security risks and countermeasures in terms of four critical components in ML systems: data input (sensor), data preprocessing, machine learning model and output. Finally, we discuss future research trends on the security of ML systems. The aim is to arise the attention of the computer security society and the ML society on security and privacy of ML systems, and so that they can work together to unlock ML’s potential to build a bright future.
