As the "new Oil of the future", large data is becoming another hot spot in the field of information technology after cloud computing and Internet of things. However, the existing information security means can not meet the requirements of information security in the age of large data. While large data brings challenges to information security, it also provides new opportunities for the development of information security. The author believes that large data has become a significant target of cyber attacks, increased the risk of privacy disclosure, threats to existing storage and security measures, as the carrier of high-level sustainable attacks. On the one hand, large data technology has become a means to exploit the hacker's attack, on the other hand, it provides new support for information security. ...

In this way, the growth rate is six times times that of the ICT (ICT) market. Big data is not only the emerging industry, but also the main driving force of the market, it is becoming an important market. Dan Vesset, vice president of IDC Business Analysis and large data research, said: "Large data technology and service representatives ...

Big data hot in the IT industry may seem like an immeasurable piece of gold, but without data security, it's more like a bayonet, hanging overhead and hitting the key! Years of speculation, criticism, questioning, then, finally came the big data belongs to its era. By 2009, the term "big data" began to receive the attention of the information technology industry. The principle of big data is very simple, people who have studied statistics understand that in statistics, the more samples are selected, the closer the statistics will be to the real ...

20 years ago, the electronic medical record was a novelty, and digital music was just a fantasy, and the word Twitter simply referred to the chirping of birds, and Google co-founder Sergey Brin was only a summer intern for Wolfram. 20 years later, the information revolution has brought tremendous changes to our lives. From the intuitive figures, the size of large data has been hard to imagine. According to the report of IDC, a market research company, 2012 years ...

The following article is mainly about wireless encryption is commonly used in wireless network encryption protocol, in the actual operation of the widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol two. The widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol. WEP protocol is also called Wired Equivalent encryption protocol, this kind of wireless communication protocol is often those who are eager to produce and sell wireless equipment in a relatively short period of time to put together the informal wireless encryption communication standards, from the current view of this wireless network encryption protocol There are quite a lot of security ...

A large data resource description model supporting efficient query retrieval Zhang Wenji Xianglenzhi Wangxiaofang The problem of large data resource description model which can not support efficient query retrieval in the form of a unified query interface, by extending the trace attribute of large data partition management model, the extension function is introduced, In order to support the construction of differentiated large data information resource organization pattern. On this basis, the inverted retrieval mode which supports high efficient retrieval of large data resources is given, and it is proved that it is much more efficient than traversal retrieval mode and hierarchical retrieval mode. At the same time, the unified query mechanism in dialect mode is given. At present, large data resources are traced ...
