DeepGuard: New AI Software Combats Deepfake Image Threats

New software will help combat deep fake image threats to personal security

Realistic images created by artificial intelligence (AI), including those generated from a text description and those used in video, pose a genuine threat to personal security. From identity theft to misuse of a personal image, spotting what's real and what's fake is getting harder and harder. A research collaboration involving the University of Portsmouth's Artificial Intelligence and Data Science (PAIDS) Research Center has developed an innovative solution to accurately distinguish between fake and genuine images, as well as identify the source of the artificial image. The solution, known as DeepGuard, combines three advanced AI techniques, which are binary classification, ensemble learning, and multi-class classification. These methods enable the AI to learn from labeled data, making smarter and more reliable predictions. It is a tool that can be used to investigate and prosecute criminal activity such as fraud, or by the media to ensure images used in their stories are authentic to prevent misinformation or unintentional bias. DeepGuard has been developed by a research team led by Dr. Gueltoum Bendiab and Yasmine Namani from the Department of Electronics at the University of Frères Mentouri in Algeria, and involving Dr. Stavros Shiaeles from the University's PAIDS Research Center and School of Computing. Dr. Shiaeles said, "With ever-evolving technological capabilities, it will be a constant challenge to spot fake images with the human eye. Manipulated images pose a significant threat to our privacy and security as they can be used to forge documents for blackmail, undermine elections, falsify electronic evidence and damage reputations, and can even be used to incite harm, by adults, to children. "People are also profiteering disingenuously on social media platforms like TikTok, where images of models are being turned into characters and animated in different scenarios in games or for entertainment. "DeepGuard, and future iterations, should prove to be a valuable security measure for verifying images, including those in videos, in a wide range of contexts." The research, published in Electronics, will also support further academic research in this area, with additional datasets available to academics. During its development, the team reviewed and analyzed methods for both image manipulation and detection, focusing specifically on fake images involving facial and bodily alterations. They considered 255 research articles published between 2016 and 2023 that examined various techniques for detecting manipulated images -- such as changes in expression, pose, voice, or other facial or bodily features.

Anyone who has access to an image or images that they believe to be connected to illegal activity can contact the Police Fraud and Cyber Security Unit or, if it is a child or adult safeguarding issue, to contact their local Police Constabulary on the non-emergency 101 telephone number. If a child or adult is in immediate danger of harm, the emergency 999 number should be used.
