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.

A mid-sized university CS department ran a controlled study comparing AST-based and token-based plagiarism detection across student assignments that had been systematically refactored. The results reveal which technique handles control flow restructuring, identifier renaming, and method reordering — and where both fail entirely.

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.
