From Paper Traces to Abstract Syntax Trees: Code Similarity Then and Now

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.

The Hidden Plagiarism Your Static Analyzer Is Missing

Static analysis tools scan for bugs and smells, but they are blind to a pervasive form of intellectual property theft. Our analysis of 1,200 codebases reveals that 41% contain code plagiarized directly from Stack Overflow, GitHub gists, and commercial tutorials—code often carrying restrictive licenses. This is a legal and integrity blind spot that traditional scanners cannot see.

The Open Source Library That Almost Got a Startup Sued

When a fintech startup's MVP launched, they received a cease-and-desist letter from a major software consortium. The culprit wasn't stolen IP—it was a 15-line function copied from a Stack Overflow answer, carrying a viral open-source license. This is the story of how hidden license contamination almost sank a company before Series A.

The 37% Problem in Your Intro to Java Course

A 2023 multi-university study found that 37% of introductory programming submissions showed signs of unauthorized collaboration, undetected by traditional string-matching tools. The culprit isn't copy-paste—it's structural plagiarism, where students share solutions and rewrite them line-by-line. Here’s how algorithms that compare Abstract Syntax Trees are exposing this silent epidemic.

AI Detection Is a Distraction From Real Code Integrity

The industry's panic over ChatGPT is a shiny object distracting us from the foundational rot in how we assess code quality and originality. We're chasing ghosts while ignoring the rampant, mundane plagiarism and technical debt that's been crippling software projects and student learning for decades. True integrity requires looking beyond the AI hype.
