Whose big data?

Speaking of large data, we are not unfamiliar, Alibaba, Tencent, Baidu and other Internet companies have long proposed large data, but also a lot of domestic and foreign companies to introduce smart hand ring, smart glasses and other wearable equipment to collect data, make it a large part of the data.

Since the big data is made up of everyone's behavior, who owns the data? This is one of the issues that many people are most concerned about.

Today, Baidu's big talk invited one of the world's top seven authoritative data experts, MIT Human Power Laboratory director Alex Pentland (Alexpentland), did the "Big data to open the big future" keynote speech. He made it clear that the ownership of data should be given back to everyone.

Interestingly, Puntland does not wear any wearable equipment because it has a high vision and does not yet have a product to look at.

Puntland has made its own understanding from the three perspectives of wearable equipment and large data collection, social physics, security of large data and privacy.

Wearable equipment and large data collection

Most people think that big data starts with search engines and computing, and Puntland, unlike most people, thinks big data starts with input data. "All the world is connected by the Internet." Every corner has a computer, someone, have information input, you can share, this is different before. How wearable devices can be embedded in cars, family life. Everyone has a smartphone, and you go wherever you go. ”

Puntland and students, 20 years ago, were wondering how to make computers even smaller? In 1994, a student in Puntland invented the products of Google Glasses, and in 1995, Motorola made them do the same thing as Apple, which is in the same vein as a wearable device. He realized more than 20 years ago that wearable equipment would be everywhere.

Wearable equipment Many applications are exciting, such as the intelligent hand ring can record heart rate, in the human cerebral cortex, many points of data can be recorded. When people use wearable equipment, they can better understand what happens when a child cries, and how he is excited. Big Data makes people more subtle, even in poker, gets a better win, someone gets the cards to bluff, but the wearable equipment's data will expose the cards he actually gets, and the same will expose the emotional performance of people at the bargaining table.

In Puntland's view, what people are looking at is not the language of conversation, but your actions. Some people cling to you in action, for example, men and women dating for three minutes, do not need to listen to what they say, can be judged by nonverbal signs, hands up, the brain responsible for the hands raised the cortex is bright, which can be done by the application. The big data judge the signs of depression, not blood pressure, but the form of speaking to them. There is also a relaxed, purely for the purpose of playing, such as the artist walked up, the tops will light up to show the walking limbs, the hair will stand up when excited, this is not our daily measure, when a person dancing for someone, it will be converted into music, it is music follow people to dance, not dance with music.

Big data is also helpful to finance, and has been achieved in Hong Kong, with big data getting through credit cards. When a person in supermarkets, gas stations and other credit card, through the previous shopping model, a few seconds to judge your next behavior, to recommend.

In particular, Puntland referred to the novel stream of thought. Big data can be used by people who are your Facebook friends. That's because, when you know who you're with, who you're calling, you're going to be able to figure out that you're 5 times times as likely to download a app as a buyer, 13 times times as many buyers as you buy a product. Now Facebook doesn't make predictions, but it's important that people meet and communicate with people who have the potential to be where you are, not just the evidence of pure numbers.

He had experimented in San Francisco, collecting data from cafes and taverns in San Francisco, and found that San Francisco was not a city, but seven or eight tribes. Through this analysis of the tribe out, conducive to advertising distribution. The crowd didn't know each other, but the same kind of people. Birds of a feather flock together, influence each other, relate to the behavior, and even have a thought of the disease, such as a group of people with diabetes 5 times times higher than the other group, for example, a group of people than the other group of people 10 times times more alcohol.

Another example is in London, two months of all traffic and crime data, where all high crime rates can be predicted; a place suddenly the old man did not go, is high crime rate.

Having said so much wearable equipment, Puntland says that it does not wear wearable equipment because it has high standards and will not wear it if it is not available. "They can't tell me useful information." I don't need the heart rate, I need to be more creative. The most interesting wearable device is that we don't have to talk, it looks at me and knows what I think. ”

Social physics

Social physics has 200 years of concept, the real wearable equipment of the future, not to measure themselves, but to measure the interaction, measuring the society.

According to Puntland, building mathematical models from sensors, this interactive way, better decisions, other ways than this good, one of the big data promises is to let us know more about ourselves, to understand the community, to understand the organization.

"Everyone is carrying a cell phone, embedding electronic components, mobile phones and my social links, people interact with, what can be done?" In the streets of Puntland, hundreds of people were found in several groups to experiment, experimenting on how team members communicated, whether they were involved, how well they understood each other, and how they interacted with each of the three points.

"This is more important than the IQ of team members, meaning that the flow of thought generates collective intelligence, which is actually IQ." He said that the group of people on the left addressed the main group, and the second set was better. Therefore, to change the collective wisdom, to change the way of communication.

As for the flow of thought in the company, he believes that any company that is most valuable is communicating, but no company can achieve it. Now the main way to communicate is email and face to face, face-to-face communication is better than email communication, even if it is the corridor of the meeting.

He said that the internal communication of a working group should be communicated more than the personality, IQ and experience of the employee. One is to see if we respect each other enough, and the second is to promote exploratory learning. Organizations will be more creative and efficient if they communicate with each other.

Another interesting point is what Puntland calls "the flow of thought on social networks." He said, think a person is clever, he buys what I buy, can do this thing in the social network, what is the best strategy? Some people buy their own newspapers, make their own decisions, others have more social attributes, and it turns out that the people who make their own decisions are stupid, and it's silly to communicate with everyone, And finding a handful of people to communicate is the most lucrative. "Better thoughts flow equals smarter society." ”

Therefore, we can predict the wealth by the mode of thought flow, reverse study, and predict poverty through the mode of thought flow. "This mode of thinking and economic thinking is not the same, economic thinking is independent, this is interconnected, economic growth at the same time management; you are more active, your friends can get prizes, mutual motivation, more than eight times times the efficiency of economic stimulation. So, better yet, social networking stimulation. "The poor local thought stream is very bad and there is no money to communicate with richer people and the crime rate is high," says Puntland.

Privacy and security of large data

Puntland says he knows that people in China are worried about companies getting their own data. "It's personal data, my behavior, my interaction with others, and personal data plays a bigger role in the future economy." He believes that the era of personal information economy has come.

Each person's data and information add up too much, it is impossible for everyone's data to be mastered by a few people. Can we find a better way to benefit the individual, the benefit of the company, and the organization's benefits? It used to be a central database for the transfer; now people are worried that the company has its own information and goes out the back door, possibly to hundreds of companies.

In the view of Puntland, personal data can measure the size of an asset, and this data is very important. Large data privacy protection is the fundamental point of commercial development, to the ownership of data to the people themselves, and now basically in the hands of the acquisition company, should be the owner of the decision to authorize who, was collected to whom, by who interpretation.

He suggested that the company first adopt the data to have the notice, then the insider agreed that the individual to audit (whether the company made a commitment to do things), the end of the user has the right to withdraw, request withdrawal can be withdrawn, "This has been discussed in the European Union and the United States." This is the basis of banking. ”
