SummaryIn the big data era, information security is becoming more and more important. The recent scandal of the data privacy on Facebook sounded the warning bell for us. Based on the utility theory, this paper proposes that the disclosure behavior of consumer personal information is mainly influenced by two factors, which are perceived risk and perceived benefit, respectively. When consumers make decisions, they weigh the risks and benefits. If the income is greater than the risk, the consumer is willing to provide the information on the website and vice versa. This paper analyzes the serious threats to the safety and privacy of commercial big data and proposes a multi‐level security protection theoretical model for business information security and privacy protection from the perspective of business big data security. The security functions and core technologies of each layer are described in detail, which provide a useful and in‐depth theoretical exploration for practical engineering. Finally, based on the privacy protection of large data and the principle of RBAC, a model of user privacy information security system is proposed.
