compares thousands of executable binary files in multiple
directories and subdirectories to thousands of other executable
binary files or source code files in order to determine which
files are the most highly correlated. BitMatch is particularly
useful for finding programs that have been copied, but where
you only have access to the program executable binary files
and not the source code.
compares every file in one directory with every file in another
directory, including all subdirectories if requested. BitMatch
produces a database that can then be exported to an HTML basic
report that lists the most highly correlated pairs of files.
You can click on any particular pair listed in the HTML basic
report see an HTML detailed report that shows the specific
items in the files (comments or identifiers) that caused the
examines all text strings, comments, and identifier names
that it can find in the executable files in order to determine
copying. If a specific user message or a unique subroutine
name is found in two files, there is a possibility that one
was copied from the other. Note that BitMatch gives only a
rough determination whether copying took place. False positives
and false negatives are both possible. CodeMatch is needed
to compare source code to make a definitive determination.
