Abstract

The invention discloses a method and a system for secure data processing in a virtual desktop. The method comprises the following steps: creating a virtual disc; redirecting file operation onto the virtual disc on an application layer; determining whether the file operation is initialized by a process of the virtual desktop on a kernel layer, if so, allowing file operation access and executing first secure data processing; converting the file operation into operation of the virtual disc on the kernel layer; and executing the operation of the virtual disc on the kernel layer so as to accomplish file operation. First secure data processing is executed on the kernel layer, therefore, for the progress of the virtual desktop, data can be processed securely during either file operation which is initialized by the application layer or file operation which is initialized by system call.

Description

technical field [0001] The invention relates to a data processing method and system, in particular to a data security processing method and system in a virtual desktop. Background technique [0002] The existing virtual desktop data security processing system includes a redirection module at the application layer and a file system driver at the kernel layer of the operating system. figure 1 Shows a logical block diagram of a virtual desktop data security processing system example in the prior art, as figure 1 As shown, firstly, the virtual desktop process initiates a file operation (such as D:\win7.dmp), and the redirection module forcibly redirects the file operation to a specified dedicated path of the virtual desktop, such as using a hook to redirect the file operation Redirect to C:\all_data\win7.dmp, where all files for the virtual desktop are stored in the specified directory C:\all_data. At the same time, the hook module of the application layer also performs securi...
