Dynamic authentication method and device for data transmission between middleware and computer medium

The invention discloses a dynamic authentication method and device for data transmission between middleware and a computer medium, belongs to the technical field of data authentication, and aims to solve the technical problem of how to realize dynamic authentication of a transmission process of medical log data from filebeat to kafka. The method comprises the following steps that: user information is inquired through a user token, and the user information and log collection parameters configured by a user are written into a filebeat default configuration file; client registration logic and client authentication logic are added in a starting module of the filebeat, and a remote interface is called to verify user information; after the filebeat client is successfully started, the filebeat client carries user information to interact with the kafka; and a user information service is called to verify the user information, the user information is locally cached through kafka, and user information authentication suc
