EducationCheating Detection4HighInstructor

Students use AI to cheat by embedding hidden instructions in prompts that cause the AI to include a specific quotation, making it detectable but difficult to prove and enforce consequences.

Current plagiarism detectors and AI output analyzers do not detect hidden prompt manipulations that instruct AI to include specific quotations, and there is no automated way to prove cheating for disciplinary action.
