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.
