Abstract
Fueled by the booming online games, there is an increasing demand for
monitoring online games in various settings. One of the application scenarios is the monitor
of computer games in school computer labs, for which an intelligent game recognition
method is required. In this paper, a method to identify game processes in accordance with
private working sets (i.e., the amount of memory occupied by a process but cannot be
shared among other processes) is introduced. Results of the W test showed that the memory
sizes occupied by the legitimate processes (e.g., the processes of common native windows
applications) and game processes followed normal distribution. Using the
T-test, a
significant difference was identified between the legitimate processes and C/S-based
computer games, in terms of the means and variances of their private working sets.
Subsequently, we derived the density functions of the private working sets of the
considered game processes and those of the legitimate processes. Given the private working
set of a process and the derived probability density functions, the probability that the
process is a legitimate process and the probability that the process is a game process can be
determined. After comparing the two probabilities, we can easily determine whether the
process is a game process or not. As revealed from the test results, the recognition accuracy
of this method for C/S-based computer games was approximately 90%.
