Abstract

The embodiment of the invention discloses a video security control method and device, equipment and a medium, and the method comprises the steps: responding to a video export request, and determining an export source identifier of a first target video, wherein the video exporting request is used for requesting to add a watermark to a first target video and exporting, the exported source identifier is generated by splicing a unique identifier of the terminal and a unique identifier distributed to a current login user on the terminal by the server; determining a watermark position dot matrix according to the pixel number of the first target video and the derived source identifier of the first target video, wherein the assignment of each point on the watermark position dot matrix is used for representing whether a watermark is added to a pixel position corresponding to the point; adding watermarks for the first target video based on the watermark position dot matrix in a mode of changing pixel values to obtain a first target video containing watermarks; and exporting the first target video containing the watermark. The method can effectively solve the video tracing problem, and ensures that the added watermark does not affect the visualization of the video content.

Description

technical field

[0001] The present application relates to the technical field of video traceability, and in particular to a video security control method, device, equipment and medium. Background technique

[0002] With the development of Internet technology, video as an information carrier has been widely used in various fields, especially with the comprehensive use of video surveillance applications in the daily life of residents, the video surveillance market, and national security. Significant issues with applications.

[0003] In practical applications, in order to prevent the video from being stolen, watermarking technology is often used to add a watermark to the video, which can effectively prevent unauthorized people from stealing, and can also trace the source well. There are currently two commonly used watermarking technologies, one of which is the implicit watermarking technology. As the name suggests, the watermarking based on this technology is not very obvious...
