Security and Privacy Data Protection Methods for Online Social Networks in the Era of Big Data

In order to improve the security of online social network security and privacy data and shorten the delay of privacy data protection, this paper proposes a method of online social network security and privacy data protection in the era of big data. In order to enhance the security of online social network security and privacy data, a network security and privacy data architecture is constructed. In view of the risk of online social network security and privacy data loss, this paper proposes a set of security and privacy data backup processing scheme. Complete the formulation of online social network security and privacy data protection scheme; Combined with the current attack methods commonly used by attackers, the shortcomings of the traditional privacy protection algorithm in protecting the security of online social network privacy data security are concluded. Design online social network security privacy data privacy protection algorithm; Finally, complete homomorphic encryption of online social network security and privacy data is adopted to realize online social network security and privacy data protection in the era of big data. Experimental results show that the proposed privacy data protection method has a shorter delay than the traditional one.
