Numerical and statistical methods are used to analyze and classify com
puter programs. Both computer source code and object files are examine
d. The results of the application of the Pearson and Spearman correlat
ion methods to the source code are coupled with the random walk model
applied to the binary code. One of the practical consequences of the a
nalysis is the ability to quantify the degree of similarity between di
fferent computer programs and, hence, identify cases of plagiarism.
