Notes
Established by multiple independent reports of the same police announcement, four of which were read in this run: The Korea Herald and the Korean-language AI Times, both from 5 March 2024, and Financial News and Newspim, both from 13 August 2026.
What the March 2024 sources establish: the National Office of Investigation put a deepfake detection tool into use, analysing a video suspected of face-swapping and returning a judgement on authenticity in five to ten minutes; a detection rate of about 80 per cent; and a training corpus of 5.2 million data points drawn from 5,400 people, including one million Korean and 130,000 other Asian samples. Officials stated at the time that because the detection rate is not complete, results guide the direction of an investigation rather than serve as evidence.
What the August 2026 sources add, and why this is recorded as operational rather than announced: the software has been applied in 1,636 investigations, including 72 election crime cases in 2026, and sits within a three-part response alongside specialist forensic video analysis and AI forensics that traces which generative program produced a file. Police reported 419 people arrested for deepfake offences between January and July 2026, with 17 detained. Those arrest figures are the output of the investigations, not of the software alone, and should not be read as a measure of its accuracy.
'vendor' is deliberately omitted. The Korean sources describe the model as domestically developed and credit the National Office of Investigation, naming no commercial supplier, while a 2024 vendor press release separately announced a deepfake detection solution developed in collaboration with the agency. This run could not establish whether these are the same system, and averaging the two would be a guess.
All four sources read for this record are Korean or Korean-English media reporting an official announcement; no primary police release was located. 'legalBasis' and 'oversight' are omitted because no source establishes either. 'techSlug' is omitted because no catalogue entry covers synthetic media detection; a technology record is proposed in the same changeset.
