Abstract:

A fuzzy evaluation method of privacy risk for library users is proposed. At first, several kinds of privacy factors and loss are qualitative analyzed, while the combination weights are set by AHP and entropy method. Then, the membership degrees are determined by fuzzy evaluation, and the degree of privacy risk are calculated by the principle of weighted average as well. The study of the case shows that the method can be effectively used to privacy risk evaluation, and the results are in accord with the reality.
