Application: Token verification method and service server using the same (Patent ID: US20240098079A1)

The patent filed by Samsung SDS Co Ltd. describes a method for token verification performed by a service server. The method involves receiving a service request message with a token from a client, conducting a first verification process using the local storage of the service server, and if the first process fails, conducting a second verification process using another service server related to the client's used service list. The service request message includes the client's used service list, and the local storage consists of a local cache and a database.

Furthermore, the method includes verifying the token using the found information in the database, storing the information in the local cache, and performing a third verification process through an authentication server if the second process fails. The service server is designed to communicate with clients, perform verification processes, and interact with other service servers based on the client's used service list. This patent outlines a comprehensive approach to token verification that involves multiple verification processes and interactions between different servers to ensure secure and efficient service delivery.
