提出了一种用于防止通过无意捕获面部图像而泄露未经授权的面部图像的方法。诸如覆盖面部和在面部上绘制特定图案的方法有效地防止了面部图像的检测，但阻碍了面对面的交流。所提出的方法通过使用戴在脸上的设备来克服这个问题，该设备通过使用光吸收和反射材料来破坏Haar特征，这使得捕获的图像中的面部大多无法检测到。该设备在外观上类似于一副眼镜，因此面对面的交流只会受到轻微的阻碍，而且它不需要电源。原型“隐私遮阳板”的测试表明，捕获的面部图像被充分破坏，以防止未经授权的面部图像泄露的面部检测。
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 corrupts the Haar-like features through the use of light absorbing and reflecting materials, which makes faces in captured images mostly undetectable. The device is similar in appearance to a pair of eyeglasses, so face-to-face communication is only slightly hindered, and it does not need a power supply. Testing of a prototype "privacy visor" showed that captured facial images are sufficiently corrupted to prevent unauthorized face image revelation by face detection.
