SIMILARITY JUDGE METHOD AND APPRATUS FOR JUDGING SIMILARITY OF PROGRAM

摘要

The present invention relates to a similarity judgment method and a similarity judgment apparatus. The similarity judgment method includes generating a call graph according to the call relation of an object program, and judging the similarity between programs by comparing the authority grade of a comparison program and the authority grade of the object program, after judging the authority grade of each node through the generated call graph. So, the call graph of the program can be generated based on the call relation of a function included in the object program.
