Abstract: With the rapid development of internet of things, edge computing and intelligent big data processing, the content of security protection has been expanded from explicit content protection to implicit content protection. The security protection of implicit content in the context of multi-source content poses new challenges to the collection, identification, customization of protection strategies, modeling and implementation of protection methods. But in practice, the pursuit of performance/cost adds more challenge to the solution. Inspired by the DIKW (data, infor-mation, knowledge, wisdom) method, this paper proposes to classify the target of protection content and background content into three types of resources: data, information and knowledge. A typed resource security protection architecture based on data graph, information graph and knowledge graph is constructed on DIKW. Target security resources are divided into explicit and implicit resources according to their existing forms in the search space, and corresponding security protection schemes are constructed according to the conversion and search cost differences corresponding to different types of resource expressions. The scheme supports the design and provision of value driven security solutions based on the differences of the conversion cost of different types of resources and the search cost after conversion.

Key words: implicit typed resources, security provision, knowledge graph
