[0003] With the development of computer technology, the security requirements for computer stored files are getting higher and higher. At present, when the stored files need to be protected, the operation permissions for the files can be set. When the operation instructions for the file do not have the operation permissions, the operation instructions are refused to be executed, thereby achieving the protection of the file. However, only protecting the file itself cannot achieve the effect of protecting the file; if the file node that is the parent directory of the file is damaged, or the file partition storing the file is attacked, the file will also be damaged.

The same reference numerals generally refer to the same components or elements.

[0028] Figure 1 FIG. 1 is a schematic diagram of a computing device testing system 100 according to an exemplary embodiment of the present invention. The file protection method 300 of the present invention can protect files in the following application scenarios. Figure 1 As shown, the computing device testing system 100 includes a control server 140 , a task server 150 , a data server 160 , and a computing device 200 that are communicatively connected to the control server 140 . Figure 1 The manner in which the computing device 200 is connected to the control server 140 is merely exemplary. The present invention does not limit the number of computing devices connected to the control server 140. The control server 140 can be connected to hundreds or thousands of computing devices to achieve simultaneous testing of a large number of computing devices and improve testing efficiency.

[0029] The task server 150 creates a test task and sends the test task to the control server 140 so that the control server 140 generates a test installation package according to the test task. At the same time, a test command is generated and the test instruction is sent to the control server 140. The test instruction instructs the computing device 200 that has installed the test installation package to execute the test items in the test task to perform the test and generate test data.

[0030] The control server 140 receives the test tasks and test commands sent by the task server 150, and generates a test installation package according to the test tasks. The control server 140 also sends the test installation package to the connected computing device 200, and forwards the test command to the computing device 200, and receives the test data returned by each computing device at the same time, obtains multiple test data, and further draws a test data table based on the multiple test data, so that the task server 150 can evaluate the performance of each computing device according to the test data table.

[0031] According to one embodiment of the present invention, the control server 140 may be provided with multiple backup servers (not shown in the figure), and the control server 140 is connected in communication with the multiple backup servers. When the control server 140 fails, the control server 140 promptly transfers the communication connection with the multiple computing devices 200 to the backup server, and the backup server acts as a control server, receives the test tasks and test commands from the task server 150, creates a test installation package, and sends the test installation package to the computing device 200, and forwards the test command. The backup server also receives the test data of each computing device, obtains multiple test data, and draws a test data table based on the multiple test data, so that the task server 150 can perform performance evaluation on each computing device according to the test data table.

[0032] The computing device 200 receives the test installation package, and installs the test installation package according to the received test installation package; the computing device 200 stores multiple pile files in the file node of the installed test installation package to protect the installed test installation package; receives the test command, executes the test task in the test installation package according to the test command to obtain the test data, and transmits the test data back to the control server 140. The pile file refers to a file used to protect the file or folder under the file node where the pile file is located.

[0033] Figure 1 The specific structures of the control server 140, the task server 150, the data server 160 and the computing device 200 in communication with the control server 140 can be implemented as follows Figure 2 The computing device shown. Figure 2 FIG. 2 shows a block diagram of a computing device 200 according to an exemplary embodiment of the present invention. Figure 2 As shown, in a basic configuration 202, computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between processor 204 and system memory 206.

[0034] Depending on the desired configuration, the processor 204 can be any type of processor, including but not limited to: a microprocessor (μP), a microcontroller (μC), a digital information processor (DSP), or any combination thereof. The processor 204 can include one or more levels of cache such as a primary cache 210 and a secondary cache 212, a processor core 214, and registers 216. An example processor core 214 can include an arithmetic logic unit (ALU), a floating point unit (FPU), a digital signal processing core (DSP core), or any combination thereof. An example memory controller 218 can be used with the processor 204, or in some implementations, the memory controller 218 can be an internal part of the processor 204.

[0035] Depending on the desired configuration, the system memory 206 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The system memory 206 may include an operating system 220, one or more programs 222, and program data 228. In some embodiments, the program 222 may be arranged to be executed by one or more processors 204 on the operating system using the program data 228 to execute the instructions 223 of the method 300 according to the present invention.

[0036] The computing device 200 may also include a storage interface bus 234. The storage interface bus 234 enables communication from storage devices 232 (e.g., removable storage 236 and non-removable storage 238) to the basic configuration 202 via the bus / interface controller 230. At least a portion of the operating system 220, the program 222, and the data 224 may be stored on the removable storage 236 and / or the non-removable storage 238, and when the computing device 200 is powered on or the program 222 is to be executed, it is loaded into the system memory 206 via the storage interface bus 234 and executed by the one or more processors 204.

[0037] The computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output devices 242, peripheral interfaces 244, and communication devices 246) to the basic configuration 202 via the bus / interface controller 230. Example output devices 242 include a graphics processing unit 248 and an audio processing unit 250. They can be configured to facilitate communication with various external devices such as a display or speakers via one or more A / V ports 252. Example peripheral interfaces 244 may include a serial interface controller 254 and a parallel interface controller 256, which may be configured to facilitate communication with external devices such as input devices (e.g., keyboards, mice, pens, voice input devices, touch input devices) or other peripherals (e.g., printers, scanners, etc.) via one or more I / O ports 258. Example communication devices 246 may include a network controller 260, which may be arranged to communicate with one or more other computing devices 262 via a network communication link via one or more communication ports 264.

[0038] A network communication link can be an example of a communication medium. Communication media can generally be embodied as computer-readable instructions, data structures, program modules in a modulated data signal such as a carrier wave or other transmission mechanism, and can include any information delivery medium. A "modulated data signal" can be a signal in which one or more of its data sets or its changes can be carried out in a manner that encodes information in the signal. As non-limiting examples, communication media can include wired media such as a wired network or a dedicated line network, and various wireless media such as sound, radio frequency (RF), microwave, infrared (IR) or other wireless media. The term computer-readable medium used herein can include both storage media and communication media.

[0039] In the computing device 200 according to the present invention, the program 222 includes multiple program instructions of the instruction execution method 300, which can instruct the processor 204 to execute some steps in the file protection method 300 running in the computing device 200 of the present invention, so that each part in the computing device 200 can protect the files of the file partition by executing the file protection method 300 of the present invention.

[0040] The computing device 200 can be implemented as a server, such as a file server 240, a database 250, a server, an application server, etc. These electronic devices can be such as personal digital assistants (PDAs), wireless network browsing devices, application-specific devices, or hybrid devices that can include any of the above functions. It can be implemented as a personal computer including desktop computers and notebook computer configurations. In some embodiments, the computing device 200 is configured to execute the file protection method 300.

[0041] Figure 3 A flow chart of a file protection method 300 according to an exemplary embodiment of the present invention is shown. The file protection method 300 in the present invention is suitable for execution in a computing device, and the computing device includes one or more file partitions. A file partition is a logical disk based on a physical disk of a computing device, and the logical disk is obtained by dividing the physical disk. The present invention does not limit the way of dividing the physical disk. Each file partition stores folders and / or files. A file refers to a collection of a group of related elements with a file name defined by the creator, which is used to store data and implement corresponding functions. A folder may include one or more files, and may include nested folders, and may also be implemented as an empty folder that does not include any content.

[0042] like Figure 3 As shown, the file protection method 300 begins at step S310, determining the number of file nodes in the file partition. A file node refers to a non-empty folder including one or more files and folders, and a file partition is also a file node. When determining the number of file nodes, all folders in the file partition are traversed to determine whether each folder is a file node.

[0043] Then, step S320 is executed to set the piling file sparsity, and the number of piling files is calculated according to the piling file sparsity and the number of file nodes. The piling file sparsity refers to the density of the piling files distributed in the file partition, that is, the probability of deploying a piling file in each file node, or represents the average number of file nodes in which a piling file is deployed. For example, if the piling file sparsity is 0.1, the probability of deploying a piling file under a file node is 0.1, and one piling file is deployed in every 10 file nodes on average.

[0044] When calculating the number of piling files, multiply the piling file sparsity by the number of file nodes to get the number of piling files. The piling file sparsity controls the number of piling files. If the piling file sparsity is low, the number of piling files is small; if the piling file sparsity is high, the number of piling files is large, which can achieve better protection for file partitions. When protecting files or folders in a file partition, the protection effect can be adjusted according to system performance by adjusting the piling file sparsity. When the number of piling files increases to a certain level, the protection effect will not increase, but the system resource consumption will increase significantly. Therefore, by adjusting the piling file sparsity, a lower system performance can be used to achieve a higher protection effect.

[0045] According to an embodiment of the present invention, the number of file nodes (innodes) of the file partition is 10,000, and the sparsity of the piling file is set to 0.01, that is, one piling file is deployed in every 100 file nodes on average. The sparsity of the piling file is multiplied by the number of file nodes to obtain the number of piling files as 100, and these 100 piling files are randomly distributed and created in 10,000 file nodes.

[0046] Subsequently, step S330 is performed to create multiple pile driving files according to the number of pile driving files, and store them in the file node in the file partition. The pile driving file refers to a file used to protect the files or folders under the file node where the pile driving file is located. The purpose of creating the pile driving file is that when the file node is operated, such as being deleted, modified, and maliciously encrypted, the pile driving file in the file node can be operated first. Once the system detects that the pile driving file is modified, the operation on the file node is blocked to protect other files or folders under the file node.

[0047] When creating a piling file, create the piling file according to the file situation stored in the file node. If the file node includes one or more files, create the piling file according to the file name, file type and file size of the file. Specifically, set the file type of the file to the file type of the piling file to ensure that the file type of the piling file is the same as the file type to be protected. When setting the file type of the piling file, when there are multiple files in a folder, these files are of the same file type, or when the number of files of a certain file type is the largest, set it according to the file type of this type of file.

[0048] Then, the file name of the stubbing file is set according to the file name, so that when the files under the file node are sorted according to the file name, the stubbing file is the first file.

[0049] When operating files in a file node, all files are generally sorted by file name. For example, files with file names starting with numbers are sorted first, files with file names starting with letters are sorted last, followed by other files with file names starting with Chinese characters. Files starting with letters are sorted in alphabetical order.

[0050] According to an embodiment of the present invention, the file node includes a file named b and a file named c, and the file name of the pile file is a. The present invention does not limit the specific form of the file name of the pile file, and a character combination that meets the requirements can be randomly selected as the file name of the pile file.

[0051] Then, the size of the piling file is set according to the file size of the file, so that the file size of the piling file is larger than the file size of the file to be protected. When there are multiple files to be protected in a folder, the size of the piling file is larger than the file size of the largest file among the multiple files to be protected. When operating the files in the file node, the files can also be sorted by file size, and the sorted files are processed in order from large to small. In order to ensure that the piling file is the first file to be processed no matter how it is sorted. When determining the size of the piling file, the file size of the piling file can be set to be slightly larger than the file size of the file to be protected to save storage space of the file partition.

[0052] According to one embodiment of the present invention, when the storage space of the file partition is insufficient, or in order to save the storage space of the file partition to a greater extent, the file size of the pile file can be set to be much smaller than the file size of the protected file, such as setting the file size of the pile file to a few bytes, 1KB or 2KB, etc. By setting the size of the pile file in the above manner, it is possible to protect the files in the file node when sorting according to the file size and processing them in order from small to large, and it is also possible to save the storage space of the file partition to the greatest extent.

[0053] The piling file is constructed according to the set file type, file name and file size of the piling file. When constructing the piling file, it is constructed according to the set piling file attributes: file type, file name and file size. According to one embodiment of the present invention, the file content of the piling file is a string generated by a random algorithm. When the piling file to be constructed is large, multiple lines of "0" characters can be interspersed between the strings in a fixed pattern as padding.

[0054] According to one embodiment of the present invention, when setting a piling file, it can also be set in the form of a piling folder, and multiple piling files can be set in the piling folder. By setting a piling folder, the time for processing the piling file can be extended, and a time window for determining whether the piling file has been modified and blocking related operations can be created, so that the system has more time to block the operation in time and avoid other files under the file node from being damaged. When creating a piling folder, the file name of the piling folder is set according to the file name of the file to be protected, so as to construct the piling folder.

[0055] According to an embodiment of the present invention, if the file node includes one or more folders, a piling folder is created according to the file name of the folder. Specifically, the file name of the piling file is set according to the file name of the folder, so that when the folders under the file node are sorted according to the file name, the piling folder is the first folder. The method of setting the file name of the piling folder is the same as the method of setting the file name of the piling file.

[0056] According to one embodiment of the present invention, when setting a pile file, not only is the pile file created by pile file sparsity, but also incremental file detection is performed on the file partition to protect newly added files or folders. When a new file or folder is detected in the file partition, a pile file is created under the file node where the new file or folder is located.

[0057] Then, step S340 is executed, and when the operation instruction for the file node is accepted and executed, it is determined whether the piling file in the file node has been changed. In order to determine whether the piling file has been changed, it is necessary to precalculate the first characteristic value of the piling file. Specifically, the file content of the piling file is converted into a file array, and then the file array is converted into binary, and the first characteristic value of the piling file is obtained according to the number of bits of the file array in binary form.

[0058] According to one embodiment of the present invention, the file content of the pile file is a string generated by a random algorithm. A larger pile file includes multiple strings, each of which is divided by multiple lines of "0" characters. The string is extracted from the file content of the pile file to obtain a file array including the string. If the pile file includes multiple strings, a file array including multiple strings is extracted from the line including the string. The file data is converted into binary, and the number of bits of the binary file data is counted to obtain a first eigenvalue.

[0059] When a pile file is operated by a non-read type, the file content of the pile file must have changed. When judging whether the pile file in the file node has changed, the second characteristic value of the pile file after executing the operation instruction is recalculated according to the above steps, and the second characteristic value is compared with the first characteristic value to determine whether the pile file has changed.

[0060] Finally, step S350 is executed. If it is determined that the pile file has been changed, the operation instruction is stopped to protect other files or folders in the file node. If the second characteristic value of the pile file is different from the first characteristic value, it is determined that the pile file has been changed, and the operation instruction is stopped to protect other files in the file node from being damaged.

[0061] According to an embodiment of the present invention, the computing device is also connected to the control server in communication, the control server is connected to one or more computing devices, and the control server is also connected to the task server in communication. The task server 150 creates a test task and sends the test task to the control server 140. The test task includes multiple test items, and the task server 150 constructs a configuration file for each test item, and combines the configuration files of the multiple test items to be tested as a test task.

[0062] The control server 140 constructs a test installation package according to the test task. The computing device receives and installs the test installation package constructed by the control server 140, and stores multiple piling files in the file node of the installed test installation package to protect the installed test installation package. The number of piling files constructed specifically can be obtained by setting the piling file sparsity and counting the number of file nodes of the test installation package. The test task in the test installation package is then executed to obtain test data, and the test data is sent to the control server; when executing the test task, when accepting and executing the operation instruction on the file node of the test installation package, it is determined whether the piling file in the file node has changed; if it is determined that the piling file has changed, the execution of the operation instruction is stopped to protect other files or folders in the file node of the test installation package.

[0063] According to an embodiment of the present invention, when the computing device determines that the stub file has been changed, it also sends a message to the control server 140 and closes the file to prevent the file from being further destroyed. After receiving the message, the control server 140 manually intervenes to restore the file of the computing device.

[0064] The file protection method of the present invention is suitable for execution in a computing device, and the computing device includes one or more file partitions. First, by determining the number of file nodes in the file partition, the sparsity of the piled file is set, and the number of piled files is calculated according to the sparsity of the piled file and the number of file nodes; multiple piled files are created according to the number of piled files; and multiple piled files are stored in the file nodes in the file partition. The number of piled files created can be adjusted according to the file sparsity. When the file sparsity is low, the number of piled files is correspondingly reduced; when the file sparsity is high, the number of piled files is correspondingly high, which has a better protection effect on the files in the file partition. When accepting and executing an operation instruction for a file node, it is determined whether the piled file in the file node has been changed. If it is determined that the piled file has been changed, the execution of the operation instruction is stopped to protect other files or folders in the file node, so as to avoid improper operation behaviors from damaging the files or folders of the file partition to be protected, prevent viruses from maliciously tampering with files, and prevent important files from being lost due to human misoperation.
