Experts recommend pushing large data strategies at the national level

For China, big numbers are opportunities and challenges. China has the largest population in the world, but only 60% of Japan and 7% of North America, half of which is unprotected. In http://www.aliyun.com/zixun/aggregation/13568.html "> Large data technology, China and the world's advanced countries, there is a huge gap, there is also a lack of relevant laws and talents. "Chinese Academy of Engineering, director of China Internet Association Hequan 26th in an interview with the Science and technology daily Reporter, said.

Hequan said that the current world data volume rapid growth, the new production data volume annual growth rate of 40%. If you load the world's data from 2011 into your ipod, you can fill 57.5 billion ipods. Use these ipods as bricks to base two great Wall of China.

Sumeng, Chairman of the Board, stressed that data exchange is a problem in the world at present. "The biggest problem is that the data are considered assets and commodities, but pricing is difficult and there is no good data pricing model internationally." The current approach is to make the data flow as much as possible, with a certain amount of data exchanged between enterprises or one-to-one enterprises. ”

"For example, a cosmetics network, one is to do clothing network, two corporate bosses are more familiar with two of the consumer groups similar to the site, are mainly female, each other can carry out customer data exchange." "If you do data exchange directly, consumers will be concerned about privacy issues, and it may be easier to accept that" use my data to improve business services to me, "said Xuanxiaohua, the Chinese Academy's data chairman.

"But also to distinguish the issue of data ownership, I Taobao shopping today, Taobao has my personal data, my behavior data is Taobao or belong to me?" At present international law thinks this data belongs to the consumer, Taobao can use, can submit user experience, but if Taobao sells this data to third party cannot. Sumeng said, but Taobao's understanding and prediction of users is not raw data, it is its analysis results. Sharing this data with third parties is now recognised in most markets in the United States, and companies such as IBM are using the data to provide services to third parties.

"In the United States, some companies integrate, process and service data, but provide a big trend to get rid of some of the ' bottom ' details of individual data to avoid some privacy and security issues." Zhao, deputy director of the large data center of the Suzhou Institute of Tsinghua University, said that in the case of large data regulation, it is necessary to have a credible institution to regulate, "the most suitable is the government". Shanghai has set up a large data bureau, which is a professional government agency for data management. The core management is "who is the data owner", "Who is the user", "How to define using rights", "How to Rank", "who is the beneficiary of the use of data", etc.

The United States promotes large data analysis as a national strategy, and the government takes the lead in opening data. Many Chinese departments have data that is not communicated, it is difficult to share, resulting in incomplete or repetitive information collection. Therefore, China needs a large data strategy at the national level, open data measures and regulations. "Hequan said.
