Method for detecting software plagiarism based upon analysis on call frequency of application programming interfaces

摘要

application programming interface (API) calls by frequency analysis software for plagiarism detection methods are disclosed It is. Software piracy detection method according to the invention cross the API call characteristic data extraction step, and the first program and the API calls the API call specific information characteristics of the second program to extract characteristic information of the API call, the first program and the second program, compared to, it may be configured to include a degree of similarity determination step of determining the degree of similarity (similarity) of the first program and the second program. Thus, the availability of source code comparison target program, or dynamically, without having to analyze, compare and analyze executable files of the target program to be effectively static detection software piracy only if the bus marks the executable file to extract the software program to be compared. can. ;
