Cloud printing method, system and storage medium

Abstract

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.

Description

technical field [0001] The invention belongs to the field of network information security, and in particular relates to a cloud printing method, system and storage medium in a cloud network. Background technique [0002] With the development of network technology, the printing method of printers has also developed from the original U disk printing or direct connection printing to the current cloud printing method. The cloud printing method directly sends printing files through the Internet, and deploys printing equipment through the cloud, which greatly improves printing efficiency and improves work convenience. [0003] However, for some commercial secrets, military-related documents, or documents that require high confidentiality, the current cloud printing method has great security risks. For example, commercial spies or enemy spies use forged printing terminals to intercept print files, attack the cloud to obtain stolen files, and attach viruses when sending print files...

Problems solved by technology

[0003] However, for some commercial secrets, military-related documents, or documents that require high confidentiality, the current cloud printing method has great security risks

For example, commercial spies or enemy spies use forged printing terminals to intercept print files, attack the cloud to obtain stolen files, and attach viruses when sending print files to printers or the cloud. This is a security issue that cloud printing cannot bypass at present.

Although some printing apps have set some encryption methods, these encryption methods are common encryption methods, and the confidentiality effect is not ideal. This leads to the fact that the current cloud printing is only suitable for some ordinary printing. Most of the current printing methods are still in the confidentiality unit At present, it is urgent to propose a safe and reliable confidential cloud printing method for confidential personnel who have high confidentiality requirements but cannot print on site
