Deepfake Forensics: Identifying Real Regions in Altered Videos with Digital Watermarking

Abstract

This paper describes a method for detecting Deepfake videos using a lightweight yet secure video encryption algorithm. With the increasing use of digital media, transferring data via the Internet or other mediums requires protection. In the proposed method a digital signature is generated and encrypted using Asymmetric Encryption (RSA). This encrypted signature is then used as a blind watermark for the video. This technique aims to detect “face swap” type of Deepfake videos. It is an efficient algorithm and has minimal impact on the perceptibility of the video quality.
