Description
Technical field
The present invention relates to single machine technical field of virtualization, in particular to a kind of watermark adding method, device and computer can
Read storage medium.
Background technique
In recent years, virtual desktop flourishes at home, including government bodies, bank, People's Armed Police etc. use successively
Virtual desktop technical substitution tradition PC.Virtual desktop is the revolution of enterprise IT architecture, brings mobile computing to experience same
When, meet the needs of many specific industries.
In the clients such as government, bank, army, information security requirement is the most important thing.In terms of information security, generally
User can be limited by technological means and carries out file transmission, peripheral hardware copy and internet permission etc., but is unable to control user
Take pictures, the behaviors such as screenshotss.
The behaviors such as digital watermarking has an important role in terms of information security and copyright protection, and user takes pictures and records a video
The file of generation also has watermark information, and specific watermark information (such as company information, user's id information) is to trace to source to mention
Foundation is supplied.
Under normal mode, realize that generally there are two types of modes for addition watermark in computer operating system, one is by third
Square application program realizes watermark function, such as watermark is added in office, wps, pdf application program, this watermark addition side
Method can not expand to other application, and versatility is not present with using close coupling in watermark function.Second of mode is to be in operation
Increase application program on system, by application program by the spatial domain of digital watermarking stacking to image.But under this mode, using journey
Sequence belongs to a process in operating system, can not limit the behavior of shutting down of user, and exists to seize etc. with other application and ask
Topic.
Summary of the invention
In order to solve in the prior art when using concrete applications programs such as word, watermark is added and applies close coupling, no
There are versatilities, or when increasing watermark addition application program on an operating system, can not limit user shuts down behavior,
And there are problems that seizing with other applications, the present invention provides a kind of watermark adding methods, device and computer-readable
Storage medium.
