Researchers have discovered a way for cell phones to find hidden cameras

Four researchers in Singapore and South Korea have developed a new method that can be used by newer mobile phones to detect hidden cameras nearby. Something that was first noticed by The Register.

The researchers call their system LAPD (Laser Assisted Photography Detection) and it uses modern mobile phones ToF sensors. The sensors are found, for example, in lidar systems and use light to measure the distance to an object.

LAPD can then illuminate a suspicious area with laser light from the ToF sensor, whereupon all hidden cameras in the area will reflect the light which is then detected by LAPD.

According to researchers, hidden cameras are a global problem. In South Korea alone, 6,800 cases of hidden spy cameras will be discovered in one year.

It is currently unknown when the source code for LAPD may become publicly available.
