ExamGuard open-source app released to detect AI glasses at exam sites
Alpaca Lab's browser-based tool scans wireless signals and inspects photos of glasses on-device; the prototype's accuracy in real venues is unverified.
An open-source web app called ExamGuard, designed to help exam invigilators check for AI smart glasses, was released online on 8 نوفمبر 2026, with its source code published on GitHub. The tool was developed by Alpaca Lab and runs in a web browser without installing separate software, according to ZDNet Korea.
ExamGuard combines three functions: wireless signal scanning, optical inspection and a physical device catalog. The wireless scanning component uses a combined filter that compares manufacturer codes, service identifiers (UUID) and data patterns, which the developers say reduces the risk of misidentifying other devices from the same maker as smart glasses.
The optical inspection function magnifies submitted glasses using camera filters such as reflection emphasis, outlines and color inversion, to look for suspicious parts including cameras or charging contacts. ExamGuard also suggests three candidate product matches based on submitted photos and can record inspection results in a report.
Photo analysis is processed on the user's device and is not sent to an external server. The released version is a prototype, and its detection accuracy in actual exam venues has not been verified.
Cheating cases prompt exam-site measures
In May, two cheating attempts using AI glasses were caught in TOEIC tests, and last month test-takers wearing smart glasses were caught in essay exams at Yonsei University and the University of Seoul. The Ministry of Education plans to place staff dedicated to identifying smart glasses at 1,312 test sites nationwide for the 2027 Suneung, scheduled for the 19th.
