Research on Preventing Unauthorized Face Image Detection

提出了一种通过无意捕获人脸图像来防止隐私侵犯的方法。诸如遮盖面部和在脸上涂上特定图案等预防方法是有效的，但会阻碍面对面的交流。提出的方法通过使用戴在脸上的设备传输近红外信号，摄像头图像传感器捕捉到的近红外信号使捕捉到的图像中的人脸无法检测，从而克服了这一问题。该设备外观类似一副眼镜，人眼无法看到信号，因此不会阻碍面对面的交流。对原型的测试表明，它可以通过对人脸图像的破坏，通过人脸检测来有效地防止隐私侵犯。

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.
