The history of code similarity detection is a story of escalating arms races. What started with professors reading printouts has evolved through Unix diffs, token-based fingerprinting, and into modern abstract syntax tree analysis. This retrospective traces the key technical shifts that shaped how we detect code plagiarism in programming courses today.

Source code plagiarism detection relies on two fundamentally different reference sets: peer submissions and the open web. This article examines the trade-offs between each approach, when one method catches cheating the other misses, and how to build detection strategies that combine both for maximum coverage.

Code similarity analysis has long been a staple of academic integrity enforcement, but enterprises face a harder problem: detecting IP theft, insider leaks, and unlicensed reuse in complex, multi-repo codebases. This post examines the practical limitations and proper applications of similarity detection for proprietary software, from AST comparison to dependency graph analysis.

The market is flooded with tools claiming to spot AI-written code with 99% accuracy. Most are built on statistical sand. We dissect the eight fundamental flaws, from dataset contamination to meaningless confidence scores, that render their outputs little better than a coin flip for serious applications.
