本发明实施例中所涉及的对虚拟文件处理方法，将作用于操作系统之上，应用程序之下，部分接管当前进程对文件的操作，产生虚拟和可控的自动化操作。通常，用户在对一个文件进行操作时，相应的处理程序会去操作系统资源，达到文件打开、创建、删除及改名等目的。The virtual file processing method involved in the embodiment of the present invention will act on the operating system and under the application program to partially take over the operation of the current process on the file to generate a virtual and controllable automatic operation. Usually, when a user operates a file, the corresponding processing program will go to the operating system resources to achieve the purpose of opening, creating, deleting and renaming the file.
实施例一：Embodiment one:
本实施例提供一种对文件虚拟化处理方法，以改名或删除文件为例。参见图1，本发明实施例，具体包括：This embodiment provides a method for virtualizing a file, taking renaming or deleting a file as an example. Referring to Fig. 1, the embodiment of the present invention specifically includes:
步骤101：获取对目标文件改名或删除的操作指令及所述目标文件的文件名信息；Step 101: Obtain an operation instruction for renaming or deleting a target file and file name information of the target file;
其中，获取对目标文件改名或删除的操作指令及所述目标文件的文件名信息可以使用一种替换系统函数的钩子技术在系统服务描述符表上截获对目标文件改名或删除的操作指令及所述目标文件的文件名信息；Wherein, obtaining the operation instruction to rename or delete the target file and the file name information of the target file can use a hook technology to replace the system function on the system service descriptor table to intercept the operation instruction to rename or delete the target file and the information of the target file. Describe the file name information of the target file;
获取对目标文件改名或删除的操作指令及所述目标文件的文件名信息也可以通过直接使用文件过滤驱动来过滤发向文件系统设备的输入/输出请求包，从中获取对目标文件改名或删除的操作指令及所述目标文件的文件名信息；Obtaining the operation instructions for renaming or deleting the target file and the file name information of the target file can also filter the input/output request packets sent to the file system device by directly using the file filter driver, and obtain the renaming or deleting information for the target file therefrom. Operation instructions and file name information of the target file;
获取对目标文件改名或删除的操作指令及所述目标文件的文件名信息的方法还有其他实施方式，在此不一一列举；There are other implementations for obtaining the operation instruction for renaming or deleting the target file and the file name information of the target file, which will not be listed here;
在实际操作中，有一些文件不需要进行虚拟化操作，例如临时文件、内存的映像文件等，这些文件虚拟化处理的意义不大。因此上述方法中还可进一步包括：In actual operation, some files do not need to be virtualized, such as temporary files, memory image files, etc., and the virtualization of these files is of little significance. Therefore also can further comprise in above-mentioned method:
步骤102：根据所述文件名信息，判断该文件是否需要进行虚拟化处理；如果是，则继续执行文件虚拟化处理程序中的步骤103；如果否，则结束虚拟化操作流程；Step 102: According to the file name information, determine whether the file needs to be virtualized; if yes, proceed to step 103 in the file virtualization processing procedure; if not, end the virtualization operation process;
其中，所述判断目标文件是否需要进行虚拟化处理的步骤，可以在整个虚拟化流程中获取到文件名信息后执行，但本实施例仅仅作为一个实施方式，不构成对所述判断目标文件是否需要进行虚拟化处理的步骤在整个方法流程中的执行顺序的限制；Wherein, the step of judging whether the target file needs to be virtualized can be executed after the file name information is obtained in the whole virtualization process, but this embodiment is only used as an implementation mode, and does not constitute a judgment on whether the target file needs to be virtualized or not. Restrictions on the execution order of the steps that need to be virtualized in the entire method flow;
其中，判断所述目标文件是否需要进行虚拟化操作，可以通过设置一个文件名信息表，将不需要虚拟化操作的文件信息配置于表中，当所述目标文件的文件名信息匹配到该文件信息配置表中的相应信息时，则结束此次虚拟化操作流程；Wherein, to determine whether the target file needs to be virtualized, a file name information table can be set to configure the file information that does not require virtualization in the table. When the file name information of the target file matches the file When the corresponding information in the information configuration table is completed, the virtualization operation process ends;
其中，对不需要进行虚拟化操作的文件的文件名信息可以提供给用户自己配置，用户可根据需求灵活配置；也可以由系统默认配置该信息表；也可以通过前述两种方法结合来配置该信息表；Among them, the file name information of the files that do not need to be virtualized can be provided to the user to configure, and the user can configure flexibly according to the needs; the information table can also be configured by the system by default; or the above two methods can be combined to configure the Information Sheet;
其中，所述的文件名信息可以包括：文件类型、文件名、文件所在存储装置中的分区信息等；Wherein, the file name information may include: file type, file name, partition information in the storage device where the file is located, etc.;
步骤103：根据所述文件名信息，判断预置的第三安全存储设备上是否包含有所述目标文件；Step 103: According to the file name information, it is judged whether the target file is included in the preset third secure storage device;
其中，所述的第三安全存储设备可以是系统默认的固定安全存储设备；可以是用户预先指定的安全存储设备，将所指定的安全存储设备作为文件的存储环境，这个存储环境可以是目录，也可以是移动介质等等，原则上只要是用户能进行读写访问的位置即可；Wherein, the third secure storage device may be a default fixed secure storage device of the system; it may be a secure storage device designated by the user in advance, and the designated secure storage device may be used as a file storage environment, and this storage environment may be a directory, It can also be a removable medium, etc. In principle, as long as it is a location where the user can read and write;
其中，本发明实施例的方法可以嵌入到现有的操作系统下的文件安全产品中，通过与这些安全产品进行通讯，所述第三安全存储设备的位置则可由用户来设定；Wherein, the method of the embodiment of the present invention can be embedded in the existing file security products under the operating system, and the position of the third secure storage device can be set by the user through communication with these security products;
步骤104：当判断得到所述第三安全存储设备上不包含所述目标文件时，则结束此次虚拟化操作流程；Step 104: When it is determined that the third secure storage device does not contain the target file, then end the virtualization operation process;
其中，用户将需要安全存储的文件存入第三安全存储设备上后，对文件的改名或删除操作需要在第三安全存储设备上进行，当第三安全存储设备上没有存储需进行改名或删除操作的文件时，则可结束此次虚拟化处理流程，按现有技术进行操作，在此不再赘述；Among them, after the user stores the files that need to be safely stored in the third safe storage device, the operation of renaming or deleting the files needs to be performed on the third safe storage device. When operating files, you can end the virtualization process and operate according to the existing technology, so I won’t go into details here;
步骤105：当判断得到所述第三安全存储设备上包含所述目标文件时，则根据所述改名或删除的操作指令，对所述第三安全存储设备上的所述目标文件完成相应的改名或删除操作；Step 105: When it is determined that the third secure storage device contains the target file, complete the corresponding renaming of the target file on the third secure storage device according to the operation instruction of renaming or deleting or delete operations;
具体实现中，以删除目标文件为例，通常当一个文件被请求删除时，在文件系统设备中会发生一个功能号为MJ-CREATE的IRP事件，它的文件对象参数中包含有“DELETE(删除)”标志，如果通过文件过滤驱动的方法截获对文件进行删除的操作指令，对功能号为MJ-CREATE的IRP进行过滤，当发现了删除标志时，并在第三安全存储设备上发现有需要删除的该文件时，就在该第三安全存储设备上完成文件删除工作；In the specific implementation, take deleting the target file as an example, usually when a file is requested to be deleted, an IRP event whose function number is MJ-CREATE will occur in the file system device, and its file object parameter contains "DELETE (delete )" sign, if the operation instruction to delete the file is intercepted by the method of file filtering driver, the IRP whose function number is MJ-CREATE is filtered, and when the delete sign is found, it is found that there is a need on the third safe storage device When the file is deleted, the file deletion work is completed on the third safe storage device;
具体实现中，对所述第三安全存储设备上的所述目标文件完成相应的操作包括：In a specific implementation, completing corresponding operations on the target file on the third secure storage device includes:
将所述目标文件的路径重定向至所述的第三安全存储设备，在所述的第三安全存储设备上进行所述指令的操作。The path of the target file is redirected to the third safe storage device, and the operation of the instruction is performed on the third safe storage device.
为了用户更方便直接的了解对文件的操作请求的处理情况，本方法实施例还可进一步包括：In order for the user to more conveniently and directly understand the processing situation of the file operation request, this embodiment of the method may further include:
步骤106：将对目标文件的按照操作指令的虚拟化处理结果反馈至用户。Step 106: Feedback the virtualization processing result of the target file according to the operation instruction to the user.
由于本实施例的方法作用于操作系统之上，应用层之下，对文件的虚拟化操作将不会影响应用程序正常使用，用户的使用习惯能够保留；并且，满足相应条件后，对文件的操作在第三安全存储设备上虚拟的进行，而用户按原有操作习惯所直接操作的存储设备上，只保留一份空的文档，而文件实质内容的存储位置在所述的第三安全存储设备上，以达到安全存储的目的。Since the method of this embodiment acts on the operating system and under the application layer, the virtualization operation of the file will not affect the normal use of the application program, and the user's usage habits can be preserved; The operation is carried out virtually on the third safe storage device, and only an empty file is kept on the storage device directly operated by the user according to the original operating habits, and the storage location of the substantial content of the file is in the third safe storage device for safe storage purposes.
实施例二：Embodiment two:
文件的读写操作都是基于系统资源文件句柄来完成的，而这些句柄的获得是通过系统创建和打开文件句柄来完成的，文件读写本身并没有对文件名进行处理，只是按照句柄资源去读取或写入文件内容，所以关于文件读写的虚拟化操作只需要关注文件句柄的打开或创建，可以简单的理解为，文件的具体读写操作都是用户去完成的，系统只需要把需要读写的文件创建或打开给用户编辑；The read and write operations of files are all done based on system resource file handles, and these handles are obtained by creating and opening file handles by the system. File reading and writing itself does not process file names, but only handles resources. Read or write file content, so the virtualization operation of file read and write only needs to pay attention to the opening or creation of the file handle. It can be simply understood that the specific read and write operations of the file are completed by the user, and the system only needs to Create or open files that need to be read and written for users to edit;
本实施例二提供一种对文件虚拟化处理方法，以打开或创建文件为例，参见图2，该方法包括：Embodiment 2 provides a method for virtualizing a file. Taking opening or creating a file as an example, as shown in FIG. 2 , the method includes:
