摘要：The security issues are extremely popular in the virtual community (VC) environment because of the uncertainties. Many works use trust mechanisms as the enhancement. However, trust has flaws in some aspects, making it uncontrollable. Discussed in this paper is the reason that risk is chosen to evaluate individual's credit. Then, risk in VC environment has several properties that are helpful to understand the relationship between VC and members. A new concept is that the capacity of risk absorbing is introduced to make the model more reasonable for usual scenario. In order to compute the capacity of risk absorbing problem, shapley value approach is utilized to equalize the risk of individuals who join the game in series. The evaluation result can provide VC computed evidence to control the individual's behavior. Copyright (c) 2014 John Wiley & Sons, Ltd.
