Identifying Plagiarism
Finding correlation between the source code
files for two different programs does not
necessarily mean the code was plagiarized. In
fact there are exactly six reasons for
correlation between programs.
- Same third-party code in both programs
- Use of the same code generation tools
- Common algorithms known and used by many
programmers
- Code written by the same author
- Commonly used identifier names (e.g.
result, index…)
- Copied/plagiarized code
As the developer of at least one of the code
bases you have analyzed, you should be able to
answer whether the first three bullets apply to
your code. The fourth bullet is there as a
reminder that if the same programmer writes two
different programs there will be a good chance
of seeing correlation between the two programs.
The fifth bullet can be filtered by using the filter
common identifiers option
when you request your CodeMatch Report (for
source code analysis) or BitMatch Report (for
binary code analysis). Once you have accounted
for the first 5 bullets then any correlation
greater than 0 is indication of copied code.
Source Code Refactoring
CodeScreener is a fast and thorough way to
identify duplicate code. To get a duplicate code
report purchase a CodeMatch report and setup the
comparison of your codebase to itself using only
the Instruction
Sequence Matching report
option.
Unauthorized Code Detection
If you have used a clean room development
process or want to be sure that no unauthorized
3rd party code is present in your software, then
CodeScreener is a fast and efficient way to
double check your software. By getting a
CodeMatch report using the same plagiarism
detection options from above to compare your
source with any unauthorized code, any non-zero
correlation score indicates copying of the
unauthorized code.
