Teaching service system and teaching service method based on cloud server

Abstract

The invention relates to a teaching service system and a teaching service method based on a cloud server. The teaching service system comprises a teaching controller, the cloud server, a plurality of teacher clients and a plurality of student clients, wherein the teaching controller is in network connection with the cloud server, the plurality of teacher clients and the plurality of student clients respectively; the cloud server is in network connection with the teaching controller; each teacher client is in network connection with the teaching controller; each student client is in network connection with the teaching controller. In the teaching service system and the teaching service method disclosed by the invention, local files are incomplete encrypted copies and cannot be used even if in case of divulging; the key data and file parameters of the files are downloaded in real time, the data size is greatly reduced, and then the requirements on network conditions are greatly reduced; the running of the teaching controller is independent of the cpu of a classroom mainframe, and encryption parameters are always not exposed to the clients; the parameters of local encrypted files does not exist locally, thus increasing a difficulty to data cracking; a channel is provided for rapid dynamic update for the files.
