提出了一种通过无意捕获人脸图像来防止未经授权的人脸图像泄露的方法。覆盖人脸和在人脸上绘制特定图案等方法有效地防止了人脸图像的检测，但阻碍了面对面的交流。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“隐私面罩”的测试表明，捕获的面部图像受到了足够的破坏，可以防止人脸检测未经授权的面部图像泄露。
A method is proposed for preventing unauthorized face image revelation through unintentional capture of facial images. Methods such as covering the face and painting particular patterns on the face effectively prevent detection of facial images 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 faces 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 captured facial images are sufficiently corrupted to prevent unauthorized face image revelation by face detection.
