Invertible Fingerprint Replacement for Image Privacy Protection

抄録

The demand for privacy protection has been increasing with the widespread use of devices that can easily take high-resolution images, such as digital cameras and smartphones. In particular, fingerprint information is one of the targets for privacy protection, but there is no research which specifically deals with fingerprint information removal to our best knowledge. In this paper, we propose a method for reversibly replacing fingerprints in an image with another fake fingerprint. This method makes it possible to automatically remove the original fingerprint information in the input image and generate a natural image. Moreover, the input image ’s fingerprint information can be easily restored from the output image only by specific persons who know the key used in the image generation process. In conclusion, we confirmed that the fingerprint information removal and restoration methods are effective by using the fingerprint authentication model.
