Dynamic data sharing method, terminal device and agent server

The invention discloses a dynamic data sharing method, a terminal device and an agent server. The dynamic data sharing method, the terminal device and the agent server are applied to the technical field of Internet information. In the method, a data owner encrypts dynamic data by using a public key thereof and uploads the encrypted data to the cloud server; the agent server generates a re-encryption key, including, the data owner and an authorized user private key, for each authorized user; each authorized user after obtaining a search keyword generates a trap door and sends the trap door to the agent server; the agent server generates a keyword label value by using the trap door and the re-encryption key and enables a cloud server to determine a corresponding dynamic data ciphertext basedon the label value, to encrypt the dynamic data ciphertext by using the re-encryption key and then to feed back the ciphertext to the authorized users; and each authorized user decrypts the dynamic data by combining with the private key thereof to obtain a corresponding dynamic data plaintext. A multi-user sharing demand for the dynamic data in a cloud storage environment is satisfied, and each authorized user can obtain the dynamic data shared in the cloud server by using the private key thereof.

Screen sharing and controlling method for video conference system

The invention relates to a computer data sharing technology, in particular to a screen sharing and controlling method for a video conference system. According to the scheme of the invention, the screen sharing and controlling method mainly comprises the following steps: a video conference terminal and a server establish communication connection with a screen, a screen sharing device and the server establish a video transmission channel, the screen sharing device collects the screen sharing data per se and sending the screen sharing data to the video conference terminal; the video conference terminal copies the received screen sharing data and forwards to the server; the server sends the screen sharing data to the screen sharing device; and finally screen sharing device receives and displays the screen sharing data. The screen sharing and controlling method for the video conference system has the advantages that: a plurality of PC desktops and mobile device desktops can be shared at the same time in the video conference, and other users can remotely adjust the resolution and other parameters of the device terminal in the parameter setting mode in the video conference. The screen sharing and controlling method is particularly suitable for the video conference system.
