The invention discloses a cloud printing method, system and storage medium. The method of the present invention enhances the encryption level of the file through the three-party encryption of the cloud, the remote terminal and the printing terminal. The cloud sends the identity information, which is then forwarded to the printing terminal by the cloud. The cloud makes a preliminary judgment on the remote terminal, and then the printing terminal judges the secret level and identity information of the remote terminal to finally determine whether the printing terminal establishes a connection with the remote terminal. In addition, since the remote terminal only corresponds to one printing terminal, if the cloud receives feedback from more than one printing terminal in the process of broadcasting the identity information of the remote terminal, it can timely identify that there is a fake printing terminal in the network where the current printing terminal is located. Improve the security of the print terminal.
