Big data refers to a large amount of data generated in the Internet era and its overall system. It should be noted that big data is not a simple data concentration and synthesis, but more importantly, it aims at data analysis and processing, and obtains relevant and valuable information and content from massive data, which is the real value of big data.
Compared with traditional data, big data has the following characteristics:
First, there is much information. With the development and popularization of the Internet, the generation of data increases exponentially, which is essentially different from the data in the traditional environment. A large number of information data also put forward higher requirements for processing capacity and storage capacity, so the data processing capacity in the era of big data has also been effectively improved.
Second, the content of information data is more diverse. Compared with traditional data, there are more kinds of data in the era of big data, including all kinds of videos, pictures and audio, and their richness is greatly increased, which puts forward higher requirements for data processing ability. In the era of big data, information protection is more important, which is not only related to the personal information security of users, but also related to the healthy development of the industry.
At present, China's work on computer network information security protection is progressing step by step. We should attach importance to the positive role of relevant advanced technologies in the era of big data, strengthen the protection and maintenance of computer network information security, effectively improve information security, protect personal information and promote the healthy development of the industry.
