What CodeMatch is

CodeMatch is a Windows program from SAFE Corporation for comparing source-code files across two directories and their subdirectories. It gives file pairs correlation scores from 0 to 100 and ranks them to help examiners focus on possible plagiarism. Its hybrid matching methods examine statements, comments and strings, instruction sequences, and identifiers. Detailed HTML reports show the material behind high correlations, while a database can be exported as an HTML summary report. The listed languages include C, C++, C#, Java, JavaScript, Python, SQL, Swift, Verilog, and VHDL. SAFE says it can usually add a requested language within days. The maker also describes uses such as finding open-source code in proprietary projects, assessing common authorship, and spotting shared standard algorithms. CodeMatch assists expert review and does not precisely pinpoint plagiarism. A SAFE press release says it can be used at no charge to compare up to 1 megabyte of source code.
