Model of Assessment of Trustworthy User Based on Fuzzy Theory under Cloud Environment

Abstract— To solve the two problems that users are independent of each other, it does not form indirect trust relationship between user and cloud service providers, and the traditional method of quantitative measures user’s granularity so small. This paper introduces model of assessment of trustworthy user based on fuzzy theory. This model divides the range of trustworthy area based on fuzzy theory in mathematical thought in moderate granularity, and introduces the impact factor that is the neighboring access interval, solves the problem of establishing between user and service providers that is indirect trust. Finally, this paper mines the important influence factors through the simulated experiment, proves this model can measure trustworthy user in directly.

Index Terms— fuzzy theory, time impact factor, cloud environment, assessment of trustworthy, membership grade.
