The importance of protecting personal information, like, a person's address or health history, is well known and commonly discussed. However, images also contain sensitive information that can compromise a person's privacy or be used for nefarious purposes. To date, most methods for preserving privacy with images have relied on obfuscation techniques, such as pixelation, blurring, or masking parts of the image. However, new face‐recognition technologies driven by deep learning are showing cracks in the old techniques. Moreover, faceless recognition is presenting a whole new set of challenges for image privacy. The core of these issues it is how to ensure privacy while still being able to see and use the image. Our solution is a model based on a generative adversarial network that protects identity information while preserving face features of the original image as much as possible. The premise is to generate a fake image of a face that shares all the same attributes as the original image, for example, a brown‐eyed child smiling. With this strategy, the image remains useful, but no person or algorithm could determine the identity of the pictured individual. The framework consists of three parts: a detection module, an image creation module, and an image transformation module. The detection module extracts the attribute labels. The image creation module generates images of faces, and the image transformation module transforms the fake features to match the attributes in the original image. A comprehensive set of experiments shows the effectiveness of the proposed framework.
