The Software IP Detective’s Handbook: Measurement, Comparison, and Infringement Detection

19. Implementation

Now that I have discussed the theory behind object code correlation and source/object code correlation, I will discuss ways of practically and efficiently implementing the theory.¹ The particular implementation discussed in this chapter is based on the implementation used in the commercial BitMatch tool that is a function of the CodeSuite program, available from S.A.F.
