Abstract

The invention provides a remote VPN digital watermark application method and device, and belongs to data security, and the method comprises the steps: obtaining identity recognition information corresponding to a connected remote VPN when a service front end is connected with the remote VPN and logs in an intranet successfully; encrypting the identity recognition information, generating a digital watermark, and transmitting the digital watermark to the service front end; adjusting the color of the digital watermark to a human eye unidentifiable state according to the display color of the service front end, and adding the color to the service front end; and when the service front end has a file external transmission behavior, identifying the digital watermark in the external transmission file, and determining the identity identification information corresponding to the external transmission file. According to the method, by adding the hidden digital watermarks invisible to human eyes, when the intranet is connected through the VPN mode, after the file external transmission behavior occurs, the external transmission file can be traced.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a remote VPN digital watermark application method and device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] When a special situation occurs and cannot log in to the intranet, most companies use VPN to remotely connect to the intranet. [0004] Existing VPNs have basically achieved the function of not being able to copy intranet files. However, the current way of VPN connection to the intranet cannot prevent VPN users from taking pictures and recording screens of intranet files. [0005] Therefore, how to provide a new solution that can solve the above technical problems is an urgent technical problem in this field. Contents of the invention [0006] The...
