Document Type and Number:
WIPO Patent Application WO/2019/114673
Kind Code:
A1
Abstract:
A minimum branch path function birthmark-based software local plagiarism evidence generation method, comprising extracting static information of programs by performing reverse analysis on the programs; extracting minimum branch path-based function birthmarks on the basis of control flow graphs, basic blocks, instruction sequences and the like of functions so as to represent behavioral characteristics of the functions; calculating a similarity degree among the function birthmarks so as to obtain similarity among the functions; and building an optimal similar subgraph set on the basis of the similarity among the functions and in combination of function call graphs, and using the optimal similar subgraph set as a judgment basis of local plagiarism between the programs and a powerful plagiarism evidence, so as to provide an initial evidence for a real software infringement case.
