图书馆用户隐私风险的模糊评估研究

Research on Fuzzy Evaluation of Privacy Risk for Library Users

设计了一种图书馆用户隐私风险的模糊评估方法,首先定性分析了图书馆用户的各类隐私风险因素及风险损失,结合AHP(analytic hierarchy process)和熵值法设置综合权重,其次运用模糊评估方法确定风险因素和风险损失的隶属度向量,并根据加权平均原则,计算隐私风险度。通过实例分析可知,该方法可以有效地应用于图书馆用户隐私风险评估,评估结果符合实际。

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 entro- py 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.
