Just stick it to your phone... Detecting illegal cameras in just 5 seconds 최근 불법촬영 범죄가 증가하면서 사회적 불안감이 가중되고 있습니다. Recently, crimes of illegal filming have been on the rise, heightening social anxiety. 이에 경찰과 과학기술정보통신부, 한국인터넷진흥원은 휴대전화에 부착해 불법촬영 기기를 탐지할 수 있는 '탐지 앱'을 개발했습니다. In response, the police, the Ministry of Science and Technology, and the Korea Internet & Security Agency have developed a 'detection app' that can be attached to a mobile phone to detect illegal filming devices. 이 앱을 사용하면 5초 이내에 불법촬영 카메라를 찾아낼 수 있습니다. Using this app, illegal filming cameras can be detected within 5 seconds. 카메라 렌즈에 대한 반사광을 탐지해 내는 원리입니다. It works on the principle of detecting reflected light from camera lenses. 휴대전화에 앱을 설치하고, 별도로 판매하는 탐지 카메라를 휴대전화에 부착하면 됩니다. You install the app on your phone and attach a separately sold detection camera to your phone. 탐지 카메라는 2만 원 후반대에 판매 중인 것으로 알려졌습니다. The detection camera is reportedly being sold for around 200,000 won. 경찰은 이 기기를 1만 대 배포할 계획입니다. The police plan to distribute 10,000 of these devices. 경찰 관계자는 "불법촬영 범죄는 피해자의 고통이 클 뿐 아니라 2차, 3차 피해로 이어지는 경우가 많다"며 "이번 탐지 앱을 통해 시민들의 불안감을 해소하고 불법촬영 범죄를 예방하는 데 도움이 됐으면 한다"고 말했습니다. A police official said, "Crimes of illegal filming cause great pain for the victims and often lead to secondary and tertiary damage. We hope that this detection app will help alleviate citizens' anxiety and prevent crimes of illegal filming."
A new AI technology called "Sweep LED" has been developed to quickly find hidden cameras in spaces prone to illegal recording, such as hotels, shared accommodations, and changing rooms. Using just a smartphone and a device emitting LED light for around $10, the technology can locate camera lenses, making it a promising tool for preventing illegal recording crimes.
The "Sweep LED" technique, developed by a team of researchers from KAIST and research institutions in Singapore, analyzes reflection patterns on an object's surface to detect hidden cameras. A modular accessory, similar to a phone case, can be attached to a smartphone, and when exposed to a light source, the device quickly identifies the camera lens.
Unlike traditional handheld detector, which requires users to physically locate the bright spot on the lens, the Sweep LED system integrates artificial intelligence to analyze the movement and shape changes of reflections under various lighting angles. In real-world tests with 30 objects, the system achieved approximately 94% detection accuracy, with the entire camera identification process taking under five seconds.
The cost of the essential components in the LED case is under $10, making it affordable enough for widespread adoption in smartphone accessories or consumer products in the future. Professor Han-jun from KAIST, the lead researcher, emphasized that illegal camera recording poses a serious threat to people's safety and privacy in everyday settings.
The study, led by research fellow Dr. Yuon Jeonghyuk, was first presented at the ACM MOBISYS 2026 international conference last June.
