Abstract：With the expansion of the application scope of computer network technology and the rapid development of the globalization information，the information content is gradually infiltrating into all walks of life. The background environment of big data is changing the world outlook of people. The arrival of the big data age not only brings about the earth shaking changes，but also changes people’s views on the world，especially the application of the computer network technology in the data age and the effective integration of the data，which not only accelerates the information processing，but also makes the information get faster and better. It is precisely because the big data has gone beyond the inherent processing mode，and can be effectively used within the scope of the existing capacity to ensure the security of computer information. All walks of life should pay attention to the application of big data，summarize the security precautions according to the content of big data，establish network information protection system for computer information，and promote the effective use and expansion of information according to different protection strategies from practice，thus making the computer information secure.

Keywords：big data；computer；information security
