Do you have privacy in the big data age?

"I clicked on my name and a familiar picture appeared on the page--I was wearing a blue shirt with my basic resume next to it ... I've opened a recently updated link to Massachusetts Avenue in Boston ... Two seconds later, I saw in the video that I had opened the heavy doors of the subway station ... I feel uncomfortable every time I see myself appearing in the video. But now, my movements have been recorded by the Lifelinear network system ...

These are fragments of this year's new book, "The Eruption," by American writer Albert Laslo Barabasi, where the "Lifelinear system", which appears to be able to record people's whereabouts every moment, is only invented by the author, not real. But the author also believes that, in the advanced technology today, with large data platform, "Lifelinear system" is not impossible to achieve. It's creepy: if there's a system out there, wouldn't our privacy be exposed in broad daylight? Big Data is a double-edged sword. Both companies and individuals will benefit from the big data explosion, but at the same time http://www.aliyun.com/zixun/aggregation/9799.html "> Privacy is nowhere to be hidden." The question that follows is: Who should this data belong to? Who has the right to use these data for analysis? Can there be a limit to this use?

Big Data Change the world

The concept of large data is relatively "young", but it is not unfamiliar to many people. The explosion of data is due to the rapid development of social networks, e-commerce and Internet of things. In the past, people just use the Internet as a form of entertainment, and now, people are living on the network platform. This makes the amount of data doubled every 18 months. The influence of massive data is not to be underestimated. Erik Brynjolfsson, a professor of economics at the MIT Sloan School of Management, Eric Brunorfson that in business, economics and other areas, decision making will increasingly be based on data and analysis rather than on experience and intuition. "Our decisions can begin to become more scientific. "He said so.

More and more enterprises want to use data storage, data analysis to bring more benefits for themselves. One of the most typical cases is that Wall Street speculators use computer programs to analyze messages from the global 340 million Weibo accounts to judge the mood, and then rate them by 1 to 50 for their shares. The principle of judgment is simple: if most people are excited, buy them; if everyone's anxiety rises, sell. The data analysis software helped the speculators get a 7% yield in the first quarter of this year.

Of course, consumers will also enjoy a more convenient and personalized service. Online shopping Mad Li (alias) every morning to open the mail, the first thing to be greeted by the major E-commerce sites sent by the subscription mail and personalized recommendations of the mail, it is really convenient for her on the internet to target a very strong choice of "sweeping style" shopping. This is the business based on the user's page stay time, browse and purchase the classification of goods and other data to make recommendations.

In addition, data analysis can be used to provide health protection for people. Kaiser Permanente, a medical management consortium based in California, collected and analyzed all clinical analysis and cost data, and found that the nerve and muscle and bone system drug "MSD" in the United States had been able to cause a heart attack and ultimately successfully withdrew from the market. "Outbreak" in the book, if the big data is fully used, in the control of epidemics will also play a magical role.
