Just bought the house you suddenly received a lot of property developers or agents of the phone and text messages, then you must feel that your information was leaked. For the big Data age, the general public will be more concerned about their privacy, 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, by using large data, you want to know that a user is a 20-30-Year-old woman who has had a child and has received a higher education, rather than wondering how many children she thy, how old this year. Another point is that large data acquisition and processing is mainly done by some large companies, they have their own strict norms and procedures to ensure information security.

Experts also gave some specific suggestions: first, 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 the Ministry of Information in accordance with the decision of the NPC, The introduction of the Internet and telecommunications Network personal Information protection regulations to protect the privacy of users, which have a certain role in 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 incidents, but also with the vast number of users themselves on the protection of personal information is not enough to have a certain relationship. Therefore, in the large data age, there is an urgent need for users to strengthen their awareness of information protection education, that is, the knowledge of safe internet access and education.

Whether you accept it or not, the big data is there, not near. Big Data has had a huge impact on our lives in our lives. On the one hand, we should strengthen the protection of personal privacy, on the other hand, we should fully adapt to the changes brought about by large data to enjoy the convenience it brings to everyone's life.
