Embodiment approach
[0112] As a possible implementation manner, the target file includes an identification bit, and the identification bit is used to identify the encoding mode of the feature value;
[0113] The manner in which the processor 501 calls the target modification file to modify the code of the target file is specifically:
[0114] Call the target modification file to modify the value of the identification bit, so as to modify the encoding method of the characteristic value.
[0115] As a possible implementation manner, the target file includes a data segment, and the identification bit may be an identification bit of the data segment;
[0116] The method for the processor 501 to call the target modification file to modify the value of the flag is as follows:

An embodiment of the present invention discloses a file protection method and apparatus. The method comprises: when detecting a processing instruction for an eigenvalue in a target file, invoking a target modifying file to modify a code of the target file to modify an encoded mode of the eigenvalue in the target file, or to modify the location at the code of the target file of the code of the eigenvalue in the target file, wherein the eigenvalue in the target file is used for a unique identification of the target file, and the target modifying file is used for processing the eigenvalue in the target file; and generating the target file according to a modified code. The method disclosed by the embodiment of the present invention can improve processing efficiency of the eigenvalue in the file.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a file protection method and device. Background technique [0002] With the continuous development of computer technology, more and more files need to be stored. Therefore, the protection of files has become an urgent problem to be solved. Among them, the file includes a characteristic value used to uniquely identify the file. When the characteristic value is obtained by a third party, the third party can destroy the file or modify the function of the file through the characteristic value. Therefore, in order to ensure the security of the file, the characteristic value needs to be processed. Since when the characteristic value is obtained by a third party, the third party can destroy the file or modify the function of the file through the characteristic value. Therefore, when the developer finds that the file is damaged or the function of the file is modified, in order to ensur...
