Method and device for evaluating service relative trust

Abstract

The invention discloses method and device for evaluating service relative trust. The method comprises the following steps of: obtaining the evaluating value of the main body on the services with the same function and grouping a service evaluating matrix by the evaluating values of the services with the same function; ordering the evaluating values of all services provided by the same main body for all service platforms in the service evaluating matrix in an ascending sequence, using the ordered values as the relative evaluating values for the relative services by the main body and grouping a service relative evaluating matrix by the relative evaluating values of all services; and obtaining the relative trust of the services according to the relative evaluating values of the services in the service relative evaluating matrix. In the network service application, the invention can obtain the relative trust of the services with the same function in different service platforms, the service evaluation is accurate and reliable, and the services with high trust can be provided for users.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technology, and in particular, to a method and device for evaluating service relative trust. Background technique [0002] With the development of the networked software service model, software applications in the network are gradually developed to be transparently provided to users in the form of services. When users perform a business, they can obtain what they need from the services provided by the service platform in the network. software to perform business. When a user obtains a service from the network, it is necessary to ensure that the selected service is credible, so as to avoid the lower trustworthiness of the entire business application execution due to the poor trust degree of a selected service, forming a bucket effect. [0003] When a user chooses a service, he usually chooses a service with a high degree of trust. Therefore, the accuracy of the evaluation of the se...

Problems solved by technology

[0004] In the process of implementing the present invention, the inventor found that the evaluation of trust degree of services in the prior art generally obtains the absolute trust degree of the service based on the actual evaluation value of the service by the subject, and evaluates the service based on the absolute trust degree, and the existing service Evaluations are all aimed at the evaluation of the trust degree of services under a single evaluation environment system. However, in networked service applications, it is often necessary to select credible services among services with the same function provided by different service platforms. Therefore, it is necessary to evaluate However, since the services are provided by different service platforms, the evaluation systems of each service platform are often heterogeneous. Therefore, if we still rely on the existing single evaluation system environment Trust evaluation method, due to the large differences in the evaluation of services under different evaluation systems, will lead to inaccurate evaluation of service trust in networked service applications, and the services provided to users will not be credible

It is impossible to accurately and reliably evaluate the trust degree of services in networked service applications
