Network Information Security Privacy Protection System in Big Data Era

Traditional information security protection is based on an information data set, at least one information can not be distinguished from its own location information. Therefore, this paper studies the network information security privacy protection system in the era of big data. The hardware of network information security privacy protection system is composed of independent monitoring layer, host layer and mixed layer. It disturbs the original data by adding random numbers and exchanging, shields the original data to unauthorized users, and achieves the purpose of privacy protection and recommendation accurate and non-destructive. The system software encrypts information according to the degree of privacy protection set by users, adopts the key management mode, solves the problem of communication security and node key update, and realizes the network information security privacy protection system.
