Research on Preventing Unauthorized Face Image Detection

提出了一种防止无意捕获面部图像侵犯隐私的方法。遮住脸和在脸上画上特定图案等预防方法是有效的，但会妨碍面对面的交流。所提出的方法克服了这一问题，通过使用佩戴在脸上的设备，该设备传输近红外信号，由相机图像传感器拾取，使捕获图像中的面部无法检测。该设备的外观类似于一副眼镜，人眼无法看到信号，因此不会阻碍面对面的交流。对原型“隐私遮阳板”的测试表明，它可以通过对面部图像的破坏来有效防止人脸检测对隐私的侵犯。

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.
