Research On E-commerce Information Security Evaluation Model And Method Based On Vague Set

With the rapid development and popularity of the Internet, E-commerce, whosetrading platform is internet, has been a fast-developing. People can purchase variouscommodity via online payment at home. The stock and flow of information in thee-commerce trade is large. In addition, the capital flow and logistics information ofthe identity information, bank accounts, enterprise resource information, strategicmanagement, financial management and customer management, are all containimportant information, which are the main keys to corporation, government. Theleakage or destruction of the information about them may be fatal. This above is aproblem which to be resolved in the field of information insecurity. As Internet’scharacteristics of openness and new attacks tools’emergency, the incidents ofinformation security arise to occur. These incidents, which related to individuals,businesses, government, banks, are institutions about theft destruction, and affect thesmooth conduct of e-commerce. Therefore, it is a hot issue for how to protectinformation in today’s society.Only by analyzing the factors that affect e-commerce information security,building e-commerce information security evaluation index system of assessmentwork, can we better understand the current and future problems, improve theinformation system and provide a clear choice for security policy. In addition, wecan provide objective and important references for the safely operation of the system.Due to the constant improvement of the e-commerce system, its structure alsobecomes more and more complex, and the exchange of information in the systembecomes more frequent, which leads to a kind of information of uncertain fuzzy.Most of the previous studies scholars on the assessment of the security ofe-commerce information aim at the qualitative point of view about the evaluation ofinformation. Even if the Fuzzy evaluation from Zadeh, which is still not satisfactory.They are important topics in the current study about how to design and build ascientific and reasonable evaluation system for e-commerce information security and how to choose more effective and rational assessment-models and methods, whichapply to evaluate e-commerce information security, and also possess the practicalsignificance with the times.This paper analyzes the problems above in e-commerce information securityassessment. It introduces Vague theoretical knowledge, and applies to theassessment of the security of e-commerce information，which based on vague’smodels and methods. According to examples, the selected index system principlesand standards, this paper builds a scientific and reasonable system of informationsecurity index. In addition, it analyzes and compares the current typical methods inthe assessment work, especially focuses on the study based on vague set theory,which includes primary and secondary comprehensive evaluation. Vague sets alsoinvolve the entropy of Vague in this process, and determining the weights of Vagueavoiding subjective factors to by Vague entropy. At last, it also introduces a sort ofmethods. In conclusion, this model, verified by practical examples, has highcredibility and is an effective and reasonable approach to information securityevaluation.
