Matrix element participated in the preparation, "Technical Standards for Data Circulation Products Based on Secure Multi-party Computing" was released in Beijing

In order to implement the national big data strategy in depth, promote the exchange and cooperation of big data industry, and show the latest development achievements of China's big data industry, from June 4 to 5, 2019, hosted by China Information and Communication Research Institute and China Communications Standards Association, big data. The 2019 Big Data Industry Summit hosted by the Technical Standards Promotion Committee was held at the Beijing International Convention Center, and the Matrix Technical Standard for Data Circulation Products Based on Secure Multi-Party Computing was published.

Embrace the data wave and lead the future

Wang Xinzhe, chief economist of the Ministry of Industry and Information Technology, and Guo Guohua, chairman of the China Communications Standards Association, attended the meeting and delivered a speech. Wang Zhiqin, vice president of China Information and Communication Research Institute, presided over the opening ceremony of the summit. The summit attracted wide attention from the big data field and related industries. More than 3,000 participants attended the conference and 50,000+ people participated in the online live broadcast.

• Apple introduced CryptoKit, an encryption developer tool, and the large-scale adoption of encryption is coming soon?
• State channel: clearing on the chain under the chain, walking on two legs – nine of the blockchain technology
• Will the currency hinder the development of Bitcoin?

The summit held six major sub-forums such as Big Data Frontier Technology Forum, Big Data Security Forum, Data Circulation and Policy Regulation Forum, Government and Urban Big Data Forum, Data Asset Management Forum, Distributed Database Technology and Key Industry Application Forum. Certificates were issued for 37 products from 25 companies in the DCA's eighth batch of big data product capability evaluations, and certificates were awarded to the winners of the "2019 Big Data Galaxy Award".

In addition, the summit set up two roundtable forums, “Uncovering Data in the Platform” and “Data Asset Management”, from the leaders of the Ministry of Industry and Information Technology, and many excellent big data field service providers, industry application customers, research institutions, and local big data supervisors in China. The leaders and experts of the organization exchanged views on the status and trends of big data policies, industries and technologies.

Publish important standards and release data value

At the meeting, the China ITT Big Data team released the "Data Asset Management Practice White Paper 4.0", "In-Memory Database White Paper", "Relational Cloud Database Application White Paper", "Urban Big Data Platform White Paper", "Trusted Data Service Series" A number of results including Standards and Standards for Data Circulation Products Based on Secure Multi-Party Computing.

Among them, the "Standard for Data Circulation Products Based on Secure Multi-party Computing" is led by the China Information and Communication Research Institute and is written by the matrix element as an important participant . For the data circulation products based on secure multi-party computing, sort out the necessary technical requirements and corresponding test methods.

"Data Circulation Product Standards Based on Secure Multi-Party Computing" Released

At present, there is a bottleneck in the release of data value. When data is shared and mined, data often needs to be transferred between the management and the user, which will involve many data security and legal issues. For example, there is a risk of data leakage and legal compliance requirements. Therefore, it is urgent to solve these problems through the technical means of landing, and fully exploit the data to achieve the release of value in compliance with regulatory requirements.

According to the standard introduction, data circulation based on secure multi-party computing is a circulation technology that protects data security in the process of data release, cross-organizational flow, etc. from the supply side to the demand side by using secure multi-party computing technology. The multi-party collaborative calculation is completed if the participant cannot obtain other party data except the calculation result.

"There are many safe multi-party computing data circulation products based on different implementation methods such as obfuscated circuits, inadvertent transmission, homomorphic encryption, blockchain, etc. on the market. Its main advantage is that real data does not transfer and can correctly complete multiple parties. Data participation in computing tasks. But at the same time there are problems, such as the impact of computing performance, product implementation differences, no uniform measurement standards, product security is difficult to verify. Therefore, the need to establish a unified standard to define MVC-based data circulation products To clarify the basic technical requirements and safety verification methods of the products,” said Wang Zhuo, Institute of Cloud Computing and Big Data, China Academy of Information and Communications Technology.

Matrix elements have long been cultivated in privacy computing. The team has invested a lot of resources to support the engineering implementation of MPC technology (safe multi-party computing). In 2018, it participated in the preparation of the "White Paper on Key Technologies of Data Circulation". As an important author of the "Data Circulation Product Standards Based on Secure Multi-party Computing", the matrix element participates in the preparation of the technical requirements part of the MPC, and defines the product, from the data-related basic capabilities, compiler computing power, data circulation management. Requirements for capabilities and product safety, robustness, stability and performance.

As an important brand summit in the industry, the Big Data Industry Summit has been held for three consecutive years, becoming an authoritative high-end platform that supports big data national strategy, panoramic display of big data industry development achievements, promotes big data industry exchange and cooperation, and discusses major issues facing development.

Matrix Element and the China Information and Communication Research Institute and other enterprises jointly published "Technical Standards for Data Circulation Products Based on Secure Multi-party Computing" was grandly released at the summit, which is conducive to the establishment of a unified standard to define MVC-based data circulation products, in compliance with regulatory requirements. In the case of the full exploitation of the value of data, to promote the circulation of data resources and maximize the value.
