Japan creates spectacles with LED lights that prevents

Japanese researchers have developed glasses that by using infrared LEDs are capable of blocking the face recognition employed by digital cameras and software.

The glasses' PrivacyVisor "created by the National Institute of Informatics, Japan (NII)," he override Face Detection, which is one of the processes of face recognition, regardless of the means by which the information is collected, "he told Efe Professor Isao Echizen, head of development.


To achieve this, the device have been installed eleven LEDs with wavelengths near infrared light to areas around the eyes, which can ignite when users do not want their faces are detected. The lights with a near-infrared light spectrum are not perceptible to the human eye, so the LEDs are invisible to a person who is facing the user.

However, since other conventional cameras that detect light range, the LED will be reflected in the photograph as a noise creating differences in brightness around the eyes that make the facial recognition fails, Echizen said. Currently, the cameras have features that allow data include information such as photographs date and location where it was taken.
