[0046] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] It should be noted that the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] The present invention provides a code protection method. Figure 1 FIG. 1 is a flow chart of a code protection method provided by an embodiment of the present invention. The method can be executed by an electronic device, and the electronic device can be implemented by software and / or hardware.

[0049] In this embodiment, the code protection method includes:

[0050] S1. parse a code protection request issued by a user based on a client, obtain a storage address of a code file carried in the request, obtain the names of all code files stored in a storage space corresponding to the storage address, and generate a code file selection interface based on the names.

[0051] The code in this embodiment is Python code. After parsing the storage address of the code file, the names of all code files stored in the storage space corresponding to the storage address can be obtained, and then a code file selection interface can be generated. The selection interface can display the names of all code files in the storage space for the user to select the code file to be protected; a code file name input box can also be set in the selection interface for the user to enter the name of the code file to be protected.

[0052] S2. Display the code file selection interface on the client interface, receive the code file to be protected selected by the user based on the code file selection interface, and determine whether the code file to be protected can be encrypted.

[0053] The user can select the code files that need to be protected on the code file selection interface according to actual needs. For example, the user can select all the code files in the storage space corresponding to the storage address as files that need to be protected; or the user can select the core code files as files that need to be protected and the general code files as files that do not need to be protected.

[0054] The determining whether the code file to be protected is encryptable includes:

[0055] A11. Obtain encryption judgment rules from a preset database, and judge whether the code in the code file to be protected complies with the encryption judgment rules;

[0056] A12. When it is determined that the code in a certain designated code file meets the encryption judgment rule, it is considered that the designated code file can be encrypted.

[0057] In this embodiment, the encryption judgment rule may be a serialization judgment rule. It has been found through testing that if the code that needs to be serialized does not comply with the serialization rule, the encrypted code will not be serialized during operation.

[0058] For example, if you use the serialization tool Pickle to perform serialization operations, in order to ensure that the program can run normally after submitting the serialized function method to spark (a computing framework), you need to refer to the official documentation of Pickle to determine whether the code in the code file to be protected complies with the rules described in the official documentation of Pickle.

[0059] In this embodiment, after determining whether the code in the code file to be protected complies with the encryption determination rule, the method further includes:

[0060] B11. If it is determined that the code in a certain designated code file does not comply with the encryption judgment rule, an error message is generated, and the error message and the designated code file are sent to the client;

[0061] B12. Receive the modified designated code file fed back by the client, and determine whether the modified designated code file complies with the encryption determination rule.

[0062] When it is determined that the specified code file does not comply with the encryption judgment rules, the code statements that do not comply with the encryption judgment rules can be extracted, and the corresponding rule entries can be summarized to generate error information. The error information and the specified code file are sent to the client so that the client user can correct the specified code file.

[0063] S3: Store the code files determined to be encryptable in the storage space corresponding to the storage address into a first folder, and store the remaining code files in the storage space corresponding to the storage address into a second folder.

[0064] In this embodiment, the first folder stores encryptable code files that need to be protected, and the second folder stores non-encryptable code files that need to be protected and code files that do not need to be protected.

[0065] S4. Convert the code in each code file in the first folder into a static type of code, compile the converted code file into a first type of file, compile each code file in the second folder into a second type of file, aggregate the first type and second type of files, and obtain a target file.

[0066] Python is an interpreted language and a high-level language. Its code type is dynamic. Compared with other programming languages ​​such as Java, C, and C++, Python is easy to learn and has higher development efficiency. Therefore, Python is more widely used. However, Python code files are similar to text files. You can use a text editor to open the code file to view the source code. Therefore, the security of Python code files cannot be guaranteed, and Python code files need to be protected.

[0067] In this embodiment, the encryption tool Cython can be used to convert the dynamic type code into a static type code. The static type code can be C / C++ code. The running speed of static type language is higher than that of dynamic type language.

[0068] The first type of file is a dynamic link library file. The suffix of the dynamic link library file in the Windows environment is .pyd, and the suffix of the dynamic link library file in the Linux environment is .so. The dynamic link library file is a file that can be directly called and is irreversible (that is, it cannot be cracked and the file security is extremely high). Therefore, the dynamic link library file can be used by multiple parties without disclosing its source code content, effectively ensuring the security of the source code.

[0069] The second type of file is a file with a suffix of .pyc. The compilation tool py_compile can be used to compile Python code files into .pyc files. The cracking of .pyc files is relatively complex. By compiling into the second type of file, a certain degree of protection can be achieved for the code files in the second folder. To ensure that the compiled second type of file can run normally, the suffix of the second type of file needs to be deleted.

[0070] In this embodiment, converting the code in each code file in the first folder into a static type of code, and compiling the converted code file into a first type of file includes:

[0071] C11. Encapsulating an operation of converting a dynamic type code into a static type code and an operation of compiling a code file into a first type file into an operation package;

[0072] C12. Acquire resource utilization information of the electronic device, and determine the target number of processes corresponding to the electronic device based on a predetermined mapping relationship between resource utilization and the number of processes and the resource utilization information;

[0073] The electronic device is the executor of the present invention. This embodiment pre-establishes a mapping relationship between resource utilization and process number. The number of processes corresponding to various resource utilizations can be determined through this mapping relationship. By comparing the current resource utilization information of the electronic device with the mapping relationship, the target number of processes that the electronic device can provide can be determined.

[0074] C13. Use the target number of processes to execute the operation package in parallel on the code files in the first folder to obtain files of the first type.

[0075] The execution of Python code is controlled by the Python virtual machine (interpreter). Python was designed to be in the main loop with only one thread executing at the same time, just like running multiple processes in a single CPU system, multiple programs can be stored in the memory, but at any time, only one program is running in the CPU. Similarly, although the Python interpreter can run multiple threads, only one thread is running in the interpreter, so the use of multi-threaded processing cannot achieve the purpose of parallel processing, so this embodiment uses multi-process parallel processing to improve processing efficiency.

[0076] The using the target number of processes to execute the operation package on the code files in the first folder in parallel comprises:

[0077] D11, sorting the code files in the first folder according to file size;

[0078] D12. Use the target number of processes to execute the operation package on the sorted code files in parallel.

[0079] Assuming that the number of target processes is 10 and the number of code files in the first folder is 80, sorting the code files in the first folder by file size can ensure that the sizes of the 10 code files executed in the same batch are similar, thereby eliminating the situation where individual processes execute slowly due to large differences in file sizes and other processes need to wait after execution, effectively improving the processing speed.

[0080] In this embodiment, before converting the code in each code file in the first folder into a static type of code, the method further includes:

[0081] Perform a syntax correctness check on each code file in the first folder and the second folder. When the syntax correctness check passes, perform the step of converting the code in each code file in the first folder into a static type of code and compiling the converted code file into a first type of file.

[0082] It can be seen from the above embodiments that the code protection method proposed by the present invention, first, generates a code file selection interface according to the storage address of the code file carried in the code protection request, receives the code file to be protected selected by the user based on the code file selection interface, and determines whether the code file to be protected can be encrypted. This step can avoid the situation that the non-encryptable code file cannot run normally after encryption; then, the code file determined to be encryptable in the storage space corresponding to the storage address is stored in the first folder, and the remaining code files in the storage space corresponding to the storage address are stored in the second folder. This step separates different types of code files; finally, the code in each code file in the first folder is converted into a static type of code, the converted code file is compiled into a file of the first type, and each code file in the second folder is compiled into a file of the second type, and the first type and the second type of files are aggregated to obtain the target file. Among them, the first type of file cannot be cracked, the second type of file is more difficult to crack, and the first type and the second type of files can be directly executed. The present invention realizes that all code files can be used by multiple parties without leaking the source code content. Therefore, the present invention comprehensively improves the security of code files.

[0083] like Figure 2 FIG. 1 is a schematic diagram of a module of a code protection device provided by an embodiment of the present invention.

[0084] The code protection device 100 of the present invention can be installed in an electronic device. According to the functions to be implemented, the code protection device 100 can include a parsing module 110, a judgment module 120, a storage module 130 and a compilation module 140. The module of the present invention can also be called a unit, which refers to a series of computer program segments that can be executed by a processor of an electronic device and can complete fixed functions, which are stored in the memory of the electronic device.

[0085] In this embodiment, the functions of each module / unit are as follows:

[0086] The parsing module 110 is used to parse the code protection request issued by the user based on the client, obtain the storage address of the code file carried in the request, obtain the names of all code files stored in the storage space corresponding to the storage address, and generate a code file selection interface based on the names.

[0087] The code in this embodiment is Python code. After parsing the storage address of the code file, the names of all code files stored in the storage space corresponding to the storage address can be obtained, and then a code file selection interface can be generated. The selection interface can display the names of all code files in the storage space for the user to select the code file to be protected; a code file name input box can also be set in the selection interface for the user to enter the name of the code file to be protected.

[0088] The judgment module 120 is used to display the code file selection interface on the client interface, receive the code file to be protected selected by the user based on the code file selection interface, and judge whether the code file to be protected can be encrypted.

[0089] The user can select the code files that need to be protected on the code file selection interface according to actual needs. For example, the user can select all the code files in the storage space corresponding to the storage address as files that need to be protected; or the user can select the core code files as files that need to be protected and the general code files as files that do not need to be protected.

[0090] The determining whether the code file to be protected is encryptable includes:

[0091] A21. Obtain encryption judgment rules from a preset database, and judge whether the code in the code file to be protected complies with the encryption judgment rules;

[0092] A22. When it is determined that the code in a certain designated code file meets the encryption judgment rule, it is considered that the designated code file can be encrypted.

[0093] In this embodiment, the encryption judgment rule may be a serialization judgment rule. It has been found through testing that if the code that needs to be serialized does not comply with the serialization rule, the encrypted code will not be serialized during operation.

[0094] For example, if you use the serialization tool Pickle to perform serialization operations, in order to ensure that the program can run normally after submitting the serialized function method to spark (a computing framework), you need to refer to the official documentation of Pickle to determine whether the code in the code file to be protected complies with the rules described in the official documentation of Pickle.

[0095] In this embodiment, after determining whether the code in the code file to be protected complies with the encryption determination rule, the determination module 120 is further configured to:

[0096] B21. If it is determined that the code in a specified code file does not comply with the encryption judgment rule, an error message is generated, and the error message and the specified code file are sent to the client;

[0097] B22. Receive the modified designated code file fed back by the client, and determine whether the modified designated code file complies with the encryption determination rule.

[0098] When it is determined that the specified code file does not comply with the encryption judgment rules, the code statements that do not comply with the encryption judgment rules can be extracted, and the corresponding rule entries can be summarized to generate error information. The error information and the specified code file are sent to the client so that the client user can correct the specified code file.

[0099] The storage module 130 is used to store the code files determined to be encryptable in the storage space corresponding to the storage address into a first folder, and store the remaining code files in the storage space corresponding to the storage address into a second folder.

[0100] In this embodiment, the first folder stores encryptable code files that need to be protected, and the second folder stores non-encryptable code files that need to be protected and code files that do not need to be protected.

[0101] The compilation module 140 is used to convert the code in each code file in the first folder into a static type of code, compile the converted code file into a first type of file, compile each code file in the second folder into a second type of file, and aggregate the first type and second type of files to obtain a target file.

[0102] Python is an interpreted language and a high-level language. Its code type is dynamic. Compared with other programming languages ​​such as Java, C, and C++, Python is easy to learn and has higher development efficiency. Therefore, Python is more widely used. However, Python code files are similar to text files. You can use a text editor to open the code file to view the source code. Therefore, the security of Python code files cannot be guaranteed, and Python code files need to be protected.

[0103] In this embodiment, the encryption tool Cython can be used to convert the dynamic type code into a static type code. The static type code can be C / C++ code. The running speed of static type language is higher than that of dynamic type language.

[0104] The first type of file is a dynamic link library file. The suffix of the dynamic link library file in the Windows environment is .pyd, and the suffix of the dynamic link library file in the Linux environment is .so. The dynamic link library file is a file that can be directly called and is irreversible (that is, it cannot be cracked and the file security is extremely high). Therefore, the dynamic link library file can be used by multiple parties without disclosing its source code content, effectively ensuring the security of the source code.

[0105] The second type of file is a file with a suffix of .pyc. The compilation tool py_compile can be used to compile Python code files into .pyc files. The cracking of .pyc files is relatively complex. By compiling into the second type of file, a certain degree of protection can be achieved for the code files in the second folder. To ensure that the compiled second type of file can run normally, the suffix of the second type of file needs to be deleted.

[0106] In this embodiment, converting the code in each code file in the first folder into a static type of code, and compiling the converted code file into a first type of file includes:

[0107] C21, encapsulating an operation of converting a dynamic type code into a static type code and an operation of compiling a code file into a first type file into an operation package;

[0108] C22, obtaining resource utilization information of the electronic device, and determining the target number of processes corresponding to the electronic device based on a predetermined mapping relationship between resource utilization and the number of processes and the resource utilization information;

[0109] The electronic device is the executor of the present invention. This embodiment pre-establishes a mapping relationship between resource utilization and process number. The number of processes corresponding to various resource utilizations can be determined through this mapping relationship. By comparing the current resource utilization information of the electronic device with the mapping relationship, the target number of processes that the electronic device can provide can be determined.

[0110] C23. Use the target number of processes to execute the operation package in parallel on the code files in the first folder to obtain files of the first type.

[0111] The execution of Python code is controlled by the Python virtual machine (interpreter). Python was designed to be in the main loop with only one thread executing at the same time, just like running multiple processes in a single CPU system, multiple programs can be stored in the memory, but at any time, only one program is running in the CPU. Similarly, although the Python interpreter can run multiple threads, only one thread is running in the interpreter, so the use of multi-threaded processing cannot achieve the purpose of parallel processing, so this embodiment uses multi-process parallel processing to improve processing efficiency.

[0112] The using the target number of processes to execute the operation package on the code files in the first folder in parallel comprises:

[0113] D21, sorting the code files in the first folder according to file size;

[0114] D22. Use the target number of processes to execute the operation package on the sorted code files in parallel.

[0115] Assuming that the number of target processes is 10 and the number of code files in the first folder is 80, sorting the code files in the first folder by file size can ensure that the sizes of the 10 code files executed in the same batch are similar, thereby eliminating the situation where individual processes execute slowly due to large differences in file sizes and other processes need to wait after execution, effectively improving the processing speed.

[0116] In this embodiment, before converting the code in each code file in the first folder into a static type of code, the compiling module 140 is further used to:

[0117] Perform a syntax correctness check on each code file in the first folder and the second folder. When the syntax correctness check passes, perform the step of converting the code in each code file in the first folder into a static type of code and compiling the converted code file into a first type of file.
