提出了一种防止无意捕获面部图像而侵犯隐私的方法。遮盖脸部、在脸上画特定图案等预防方法虽然有效，但阻碍了面对面的交流。所提出的方法通过使用佩戴在面部的设备来传输由相机图像传感器拾取的近红外信号，从而使得捕获图像中的面部无法被检测到，从而克服了这个问题。该设备外观类似于一副眼镜，人眼无法看到信号，因此不会妨碍面对面的交流。对原型“隐私面罩”的测试表明，它可以通过破坏面部图像来有效防止通过面部检测进行的隐私侵犯。
A method is proposed for preventing privacy invasion through unintentional capture of facial images. Prevention methods such as covering the face and painting particular patterns on the face are effective but hinder face-to-face communication. The proposed method overcomes this problem through the use of a device worn on the face that transmits near-infrared signals that are picked up by camera image sensors, which makes the face in captured images undetectable. The device is similar in appearance to a pair of eyeglasses, and the signals cannot be seen by the human eye, so face-to-face communication is not hindered. Testing of a prototype "privacy visor" showed that it can effectively prevent privacy invasion via face detection by corrupting the facial images.
