Big Data age.

Big Data is one of the most popular words in the world today, and people are discussing the scientific and technological advances and the great value of the big data. Some people even describe the big data as the oil of the future world, and others claim that those who master the big data can overlook the whole world like God. Victor, the author of the Big Data age, said in the big data era that the world will enter a big data age in the 2020. So what is the big data, what are the characteristics, what is the impact of big data on industry, especially the general public, what should we pay attention to when we discuss big data, and the experts who participate in the 36th phase of scientists and media face-to-face activities will interpret this.

The world can be seen as a history of information, and the revolution in data or information technology will usher in a revolutionary change in human beings. 100,000 years ago in the Voice age, 5,000 years ago, the invention of words and the invention of printing 1000 years ago brought about great social change.

What's the big data?

The National Library has a collection of 26 million volumes, which, if viewed from the data, produce one year of data equivalent to the total amount of data in half the National library. He Baohong, director of the Internet center of the Ministry of Industry and Information technology, said that when an era's people have no way to use the tools of that era to deal with the data can be called large data. Large numbers are not now available, and large data are now data that modern tools cannot handle. In fact, the Ancients will encounter the same problems, such as the census, China in the Eastern Han Dynasty, there are tens of millions of people, this is clearly a big data.

Xinsheng, vice chairman and secretary General of China Communications Society, believes that the core driving force behind big data is the desire to be able to record the things that exist in real physics, to measure it, and to analyze it. With the development of cloud computing, people will use the cloud platform, through the advanced technology from the vast amount of information to dig out the quality, valuable data, so that a large number of valuable data can be converted into knowledge.

When it comes to big data, what we often know is that the data is very large, but what are the characteristics of it? Xinsheng that the characteristics of large data should have the following several aspects. The first is that the volume is particularly large, now the data unit has reached the TB,PB from GB, even EB. The second is diversity, the vast majority of the large data is unstructured, and its species is very complex. Our present technical means are not able to deal with this. Again, the speed, the frequency of data generation and the frequency of transmission is very fast. Finally, value, from a large number of low-quality, low-value data to obtain knowledge, as if from a haystack, the cost of obtaining data is very high, relative data volume, although high-quality, high value of data, but still need to dig value. These characteristics also bring about changes, including the expansion of the data from the local or sample to the entire data, the expansion of the data from the result to the process data, and the extension from the static storage data to the dynamic stream.

What's the use of big data?

When you open a Web page, it pops up ads for your favorite product, which is an example of using large data for precision marketing.

Tang Xiongyan, chief expert of China Unicom Network Technology Research Institute, tells us which organizations or applications have mastered our "traces" Baidu Master your privacy, micro-trust know your social circle, Taobao understand your shopping habits, the three operators have your phone records and online records, UnionPay knows where you use the credit card, Positioning software to know where you are now ...

Big data has brought huge value to businesses and businesses, such as reducing non-performing loan rates and reducing transaction costs in the Internet financial sector. Google uses big data to predict the outbreak and spread of seasonal flu. At&t sells data to advertisers on the location of the WiFi network, the history of the Web browsing, and the applications used. When the user is very close to the merchant, it is possible to receive the discounted electronic coupons offered by the merchant, and so on.

But as a large data generation, what can the general public gain from the development of large data? The development of large data is related to the practical interests of the general public, for example, experts believe that the use of large data can effectively achieve "intelligent medical care" for comprehensive personal health management services; Individuals can facilitate access to hospital information , examining data, medical imaging, and historical data on personal health, providing remote data analysis and service for chronic patients, assisting with clinical diagnosis and decision making, providing timely statistical analysis for public health institutions, and providing data analysis for drug development and treatment program design. With the development of large data, the life of the general public will become more convenient.

What do we do in the big data age?

When you've just bought a house, you suddenly get a lot of phone calls and text messages from real estate developers or agents, and you'll feel like your information is leaking. For the big Data age, the general public will be more concerned about their privacy and information, and how should we protect our privacy?

Experts believe that the big Data age focuses on the characteristics of the user, not the specific information. For example, a large number of people want to know that the user is a 20-30-year-old child with children and received a higher education of women, rather than want to know she thy, how old this year, there are several children. Another point is that large data acquisition and processing mainly by some large companies in the processing, they have their own strict norms and procedures to ensure information security. But at the same time, experts have given some concrete suggestions.

First of all, the state-related laws also on the protection of personal privacy, the relevant provisions and constraints, the January 2013 National People's Congress passed the Decision on privacy protection of individual users, at the same time, according to the decision of the NPC, issued on the Internet and Telecommunications Network personal Information protection regulations to protect user privacy, All of these have a certain effect on the protection of personal privacy. Second, enterprises should fulfill their social responsibility, through specific technical means to the user information irreversible treatment. Once the user information leaked, the enterprise should bear the corresponding responsibility. Finally, users need to be careful to protect their privacy. Some information disclosure events and the majority of users themselves on the protection of personal information lack of awareness of a certain relationship, so in the large data era, the urgent need to strengthen their own information protection awareness of education, that is, the knowledge of safe internet access and education.

Whether you accept it or not, the big data is there, not near. Large data has been in our lives and has brought about and will continue to affect our lives, so on the one hand we need to strengthen the protection of personal privacy, on the other hand, we should make full use of the big data to bring us changes.
