Abstract

The embodiment of the present invention discloses a method and a device for detecting the number of process instances based on memory mapping files, which are used for more concealed detection of the number of process instances existing at the same time. The method in the embodiment of the present invention includes: defining a data storage format for writing a process into a memory-mapped file; obtaining the process unique identifier of the process, and encrypting the process unique identifier of the process to obtain the encrypted KEY and the encrypted process unique identifier; The process unique identifier changes with the power-on status; create a memory-mapped file, and write the characteristic code into the head end of the internal mapping file according to the data storage format, and write the encrypted KEY and the unique process identifier of the process into the memory map file; when it is necessary to detect the actual number of the current process, read the memory-mapped file according to the data storage format, and decrypt the encrypted process unique identifier to obtain the decrypted process unique identifier, which is the number of current process instances.

Description

Technical field [0001] The present invention relates to the field of development platforms, in particular, it relates to a method and apparatus based on a detection process memory-mapped file instance number. Background technique [0002] For some PC client program, a system can only create an instance of the program, open multiple possible cheating there, but also affect the normal functions of the program, but also greatly affected the performance right. Most existing detection methods by creating a mutex variable to determine whether the instance has been created, or the name of the process to determine whether there are multiple copies of the same. However, such detection methods are well known, and has been detected can be easily bypassed. A method is needed even more to hide. Inventive content [0003] Embodiment of the present invention provides a method and apparatus for detecting the number of process instances based on memory-mapped file for the number of detected at t...
