类型化隐式资源的隐私保护方法

针对隐式隐私资源的建模和表述，给出了一个基于元建模的对隐式资源概念进行语义界定的元模型概念体系，解释了数据-信息-知识-智慧（DIKW）架构中的数据、信息、知识和智慧等基本类型化资源概念.基于DIKW资源概念将现有知识图谱概念扩展为数据图谱、信息图谱和知识图谱，进而提出了一种基于相同内容的不同资源表达处理效率差异和转换代价差异的可自动抽象调整的隐私保护解决架构.根据要保护隐私目标的以计算代价衡量的保护程度，制定将目标资源转换为何种类型资源.通过对目标资源保护者的投入保护代价和攻击者的攻击代价的差异进行衡量，选择最优的转换程度.

Privacy Protection Strategy for Implicit Typed Resources

Aiming at modeling and expressing of implicit privacy resources, a meta-model is proposed for semantic definition of implicit resource concepts. The meta-model explains the core concepts in data, information, knowledge wisdom (DIKW) architecture. Based on the DIKW resource concept, the existing knowledge map concept is extended to data graph, information graph and knowledge graph. An automatic abstract adjustment privacy protection solution is presented based on the difference of the processing efficiency of the same content expressed in different types of resources. Protection is specified as what types of resources to be converted and how much the conversions to be performed towards an optimal solution balancing the comprehensive value of both the investment of the protection side and the cost of attackers.
