SEOUL, Police have developed a software tool to detect deepfakes that could be used to clamp down on crimes using such deep learning technology, the National Office of Investigation (NOI) said Tuesday. The NOI under the National Police Agency said the software discerns whether a video suspected of being a deepfake or digitally fabricated is authentic in just five to 10 minutes. It will also immediately generate a result sheet that could be used in investigations, police added. Deepfake, a term coined by combining "deep learning" and "fake," refers to digitally manipulated images or videos that could lead viewers to wrongly perceive the processed media to be real, often becoming a source of fake news, fraud and defamation. Unlike the existing model that was trained with Western-based data, the new software learned 5.2 million pieces of data from some 5,400 Koreans and related figures and adopted the newest AI model to respond to new types of hoax videos that were not pretrained, police said. Police said th e software has an 80 percent probability of detecting whether a video is authentic, adding they will use the data to direct the investigation rather than as direct evidence. It also plans to minimize the chances of erroneous detection by cross-checking with AI experts, including academia and companies when it comes to electoral disinformation offenses.
