Research on information security and privacy protection model based on consumer behavior in big data environment

Abstract

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.

Analysis of implementation for big data techniques in consumer behavior

“…The fifth and final step is that the consumer ultimately agrees to purchase the product. Big data technology can collect these transaction data in this final step, further expand and refine the consumer profile, thereby increasing the probability of the next purchase by this consumer [9]. Overall, big data technology can be helpful in all five steps of the AIDMA model.…”

A secure and efficient WSN by employing symmetric key matrix and rectangular frame scheme

“…WSN as a wireless communication system composes of many sensing devices distributed in space. These devices employ sensors to monitor our environmental conditions and changes or perform ecological monitoring, healthcare monitoring, home automation, traffic control, etc.…”

“…This study focuses on two aspects, ie, transmission efficiency and security . To achieve the former, the virtual GPS mechanism and the Rectangular Frame with Dynamic Routing mechanism (RFDR for short), which will be described later, are used.…”
