Based on these principles and considering the grid service environment, we mainly study the following contents: (1) Establish an effective privacy protection model based on grid service, introduce the concept of reputation, and study the corresponding privacy protection methods and technologies. (2) The negotiation mechanism is introduced to study the privacy protection methods and technologies of personalized grid services. (3) Introduce the contract mechanism to study the privacy protection methods and technologies of temporary grid services. (4) Introducing ontology theory to study privacy protection technology based on semantic grid service. This field was supported by the Natural Science Foundation of Guangdong Provincial Department of Education "Research on Privacy Protection Technology Based on Grid Services", and some papers were hired by publications such as Computer Science and Computer Application Research.
