judge whether a image is from twice photographing(living User->image X->image XX)

if you can provide a high performance and accuracy, the price is negotiable 基于图片中的破绽分析，判断其中的人脸是否为二次翻拍（举例：如用户A用手机拍摄了一张包含人脸的图片一，用户B翻拍了图片一得到了图片二，并用图片二伪造成用户A去进行识别操作，这种情况普遍发生在金融开户、实名认证等环节。）； judge whether a image is from twice photographing(living User->image X->image XX), based on the analysis of the flaw in the image, then we can prevent people to do the authentication with image XX for example: the camera photographed a image from user A, we call this image as image X; user B photographed a image from image X, we call this image as image XX(we can see that image XX is not from a living people, it is from image X); then user B used image XX to simulated user A to do the authentication we should have ability to judge whether the image photographed by camera is a kind of "image XX" or not, then we can prevent the illegal authentication
