Abstract

The embodiment of the invention discloses a method and device for detecting the number of process instances based on a memory mapping file, which is used for detecting the number of process instancesexisting at the same time more concealed. The method of the embodiment of the invention comprises the following steps of defining a data storage format for writing a process into a memory mapping file; obtaining the unique process identification of the process, and encrypting the unique process identification of the process to obtain the encrypted KEY and the encrypted unique process identification, wherein the encrypted unique process identification changes with the change of the boot state; creating a memory map file, and writing the signature into the head end of the internal map file according to the data storage format, and writing the unique identification of the encrypted KEY and the process into the memory map file; when it is necessary to detect the number of actual inversions ofthe current process, reading the memory mapping file according to the data storage format, and decrypting the encrypted process unique identifier to obtain the decrypted process unique identifier, namely the number of the current process instances.

Description

technical field [0001] The invention relates to the field of development platforms, in particular to a method and a device for detecting the number of process instances based on memory mapping files. Background technique [0002] For some PC client programs, one system can only create one instance of the program, and if multiple instances are opened at the same time, there is a possibility of cheating, and it will also affect the normal functions of the program and have a great impact on performance. Most of the existing detection methods judge whether the instance has been created by creating a mutex variable, or judge whether there are multiple copies of the same process name. However, such detection methods are well known and easily bypassed. So a more concealed approach is needed. Contents of the invention [0003] Embodiments of the present invention provide a method and device for detecting the number of process instances based on memory-mapped files, which are use...
