During the 'Thirteenth Five-Year Plan' period, the compound annual growth rate of China's big data industry exceeded 30%, and the industrial scale exceeded 1.3 trillion yuan in 2021 ... According to the data of the Ministry of Industry and Information Technology, the scale of China's big data industry grew rapidly, and the big data industry chain was initially formed. At the same time, around further promoting the efficient and compliant circulation and use of data elements, and promoting the integration and open sharing of data resources, many departments are actively deploying to fully tap the value of data elements.

Insiders pointed out that with the implementation of data security law, personal information protection law and other laws and regulations, China's data market has entered a new stage of compliance development. Data security and privacy protection have become important consensus, and a safe and efficient unified data market has begun to be built.

Promote open data development and value release

In recent years, the development of China's big data industry has entered a fast lane, and the development and utilization of data resources have achieved initial results.

'Big data applications have gradually expanded from the Internet, finance, telecommunications and other fields to intelligent manufacturing, digital society, digital government and other fields, which has greatly enriched China's data resources and spawned a number of new scenes, new models and new formats.' Minister of Industry and Information Technology Xiao Yaqing said at the 2022 China International Big Data Industry Expo.

Cao Shumin, deputy director of the Central Network Information Office, said that in the past five years, the number of provincial public data open platforms has increased from 5 to 24, and the number of open effective data sets has increased from 8,398 to nearly 250,000.

Cao Shumin said that there are still some problems in China's data field, such as the lack of ownership system, unclear circulation rules, and lack of overall planning of data governance. It is necessary to speed up the establishment and improvement of basic systems such as data ownership, circulation, and trading, promote the open development and value release of data, and help the development of high-quality digital economy.

It is understood that many departments are actively deploying around further mining the value of data elements and promoting the integration and open sharing of data resources.

'Collecting, managing and making good use of data is the key to the development and growth of big data industry.' Xiao Yaqing said that it will strengthen departmental linkage, coordination between ministries and provinces, speed up the construction of basic system norms such as data confirmation, transaction circulation, cross-border transmission and security, and explore various forms of data transaction modes. Encourage Internet companies, telecom operators, industrial enterprises and other enterprises to open data in an orderly manner, and implement national standards for data management capabilities. We will continue to support the construction of data exchanges, improve the operating system and cultivate a number of data transaction service providers.

Lin Nianxiu, deputy director of the National Development and Reform Commission (NDRC), said that it will speed up the release of the policy documents on building the data infrastructure system, optimize the overall layout of the national data market system, further promote the efficient and compliant circulation and use of data elements, implement the layout of the national integrated big data center, further promote the 'East-West Calculation' project, and pay close attention to the construction of about 10 data center clusters throughout the country.

Improve the data security governance system

While the value of data is becoming increasingly prominent, the problem of data security has also attracted much attention.

Qi Xiangdong, chairman of Qixin Group, said that under the huge and complex scenario, the whole life cycle of data faces huge security risks. Many enterprises' data are in a 'streaking' state, and the basic protection of important data assets is not in place, including weak management of privileged accounts, weak control measures of authority, and lack of risk perception ability, etc., which is the primary problem of data security.

Qi Xiangdong said that with the advancement of 'East Counting and West Counting', there is a greater demand for computing power, more data circulation nodes and data volumes, and the coordination between the east and the west, which will require a higher level of data security protection.

It is worth noting that relevant departments will further improve the data security governance system.

Du Guangda, deputy director of the Network Security Administration of the Ministry of Industry and Information Technology, said during the 2022 China International Big Data Industry Expo that it would strengthen the system construction, speed up the improvement of supporting laws, regulations and policies of data security laws such as industry management and emergency plans, and provide a basic basis for data security. Establish working mechanisms, accurately grasp the responsibilities of different subjects, and establish working mechanisms such as important data filing, risk assessment, and information sharing. Strengthen the guidance of standards, speed up the development of important data identification, security protection, risk assessment and other standards, and give full play to the basic and leading role of standards.

The data security industry ecology will also be further improved. Du Guangda said that it will strengthen key technology research, face the major demand of national data security, accelerate the basic research of data security, research and development of core technologies and key products, and enhance the industrial supply capacity. Strengthen the construction of innovation carriers, vigorously promote the construction of innovation carriers such as data security industrial parks and key laboratories, foster the establishment of an industrial organization system with progressive and coordinated development of large and medium-sized enterprises, and create a source of integration and convergence of innovative resources such as technology, talents and capital.

Giving consideration to data flow and security protection

In the eyes of the industry, promoting the orderly flow and efficient release of data elements on the premise of ensuring data security is the core issue of the healthy development of the data market.

Wei Liang, vice president of China Information and Communication Research Institute, believes that the current data protection focus has shifted from relatively static security of data interaction to dynamic security of data element circulation. In this context, homomorphic encryption, differential privacy and other technologies provide strong support for resolving the contradiction between data utilization and data protection.

'Privacy computing provides a new idea of data protection.' Tian Tian, CEO of Lai Wisdom, said that the application of privacy computing technology is of great significance. First, privacy computing has the advantages of keeping original data out of the domain, encrypting the computing process and not sharing plaintext data, which can effectively protect data security and user privacy; Second, based on legal and compliant data utilization, breaking data barriers, enabling multi-party collaboration and driving business innovation; Thirdly, the data transaction and value accounting are rationalized by separating the ownership and use right of the data, not trading the data itself, but only trading the calculation results of the data.

In fact, the demand for compliant data circulation in various fields is increasingly strong, and privacy computing has been brought into digital development planning in many places. Some places have proposed to build new data infrastructure including privacy computing.

'At present, the private computing market is still in the early stage of large-scale commercial application.' Tian said that with the continuous maturity of technology and the improvement of market awareness, privacy computing will continue to provide a credible data base for high-value scenarios and help the development of digital economy.
