Application of Big Data in Security Precaution by Network Technology and Video Image Database
Abstract The security industry is generated by the needs of modern public security precaution. With the popularization of hardware and network technology, the amount of data in the field of security increases rapidly. Under such a condition, big data technology in the field of security arises. This paper discusses the current situation of the security industry, and discusses the related security problems in the application process of big data in the field of public security precaution. Taking the video image database application platform as an example, combined with the national standards 28181, 25724, 35114, this paper discusses the data security problems involved in the process of data acquisition and data transmission. Based on the Kerberos authentication mechanism of Hadoop, this paper introduces the big data security and access control technology, and forms relevant solutions in the whole process of data acquisition, data transmission and data access.
