Cloud platform dynamic watermark generation system and control method thereof

Abstract

The invention relates to a cloud platform dynamic watermark generation system and a control method thereof. The system comprises a virtual machine connection module, a watermark generation module in bidirectional connection with the virtual machine connection module and a data module in unidirectional connection with the virtual machine connection module, wherein the watermark generation module is also in unidirectional connection with the data module; the watermark generation module generates a dynamic watermark according to basic information, stored in the data module, of a virtual machine and dynamic watermark generation switch and static watermark configuration information selection, and the dynamic watermark is interposed into to-be-sent data flow through the virtual machine connection module; and the virtual machine connection module can also immediately notify the watermark generation module to generate a new dynamic watermark according to specific information of a client to adapt to the client connected with the virtual machine connection module. Through the cloud platform dynamic watermark generation system and the control method thereof, watermarks can be dynamically generated according to different virtual machine configuration information, and copyright protection can be realized when the dynamic watermarks are interposed into the data flow sent to the client by the virtual machine.

Description

technical field [0001] The invention relates to the field of copyright protection, in particular to the field of copyright protection of watermarking in data transmission in a cloud platform, and specifically refers to a cloud platform dynamic watermark generation system and a control method thereof. Background technique [0002] The cloud platform is turning to cloud computing (cloud computing), which is a major change that the industry will face. The emergence of various cloud platforms is one of the most important aspects of this transformation. As the name suggests, this kind of platform allows developers to either run the written programs in the "cloud", or use the services provided in the "cloud", or both. As for the name of this platform, now we can hear more than one name, such as on-demand platform (on-demand platform), platform as a service (platform as a service, PaaS) and so on. But whatever you call it, this new way of supporting apps has huge potential. [0...

Problems solved by technology

[0004] In the prior art, watermarks are often used to protect the copyright of data, but the content of the watermark is single, and it needs to be manually set to change, causing a lot of inconvenience, and due to the increase in the amount of data, it has become very difficult to protect its copyright by a static watermark. difficulty
