, “[Digital Daily’s Chae Seong-oh] South Korea’s three major telecommunications companies have declared ‘war on voice phishing’. With the acquisition of real-time voice phishing detection technology based on artificial intelligence (AI), they plan to apply this to commercial services to counter related damages.”,
,
, “On the 18th, KT announced that it had received approval from the Ministry of Science and ICT’s regulatory sandbox for its ‘KT Real-Time Call Voice Phishing Detection Service’, which uses AI technology to automatically detect voice phishing during real-time calls. Following SK Telecom and LG Uplus, KT is now able to roll out this service.”,
,
, “The real-time call voice phishing detection service uses an on-device AI technology that does not require server connectivity to notify users of the risk of voice phishing during real-time calls.”,
,
, “Notably, the newly approved service goes a step beyond the existing ‘Voice Phishing Detection AI Agent’ technology that detects financial scam contexts within call audio in real time. It adds a feature that analyzes the voice similarity by comparing suspicious calls with characteristic information of past voice phishing criminals’ voices using speaker recognition technology.”,

,
, “The similarity measurement is conducted using data provided by the National Forensic Service, which extracts features of voice phishing voices, and operates on-device without server connections. The National Forensic Service participates with KT in this regulatory sandbox to cooperate on improving voice phishing detection performance.”,
,
, “Following the approval of the ICT regulatory sandbox, KT plans to launch the real-time call voice phishing detection technology on VP Inc.’s spam blocker app ‘WhoWho’. Through this, they aim to improve the performance of AI technology and enhance the service.”,
,
, “Previously, on the 14th, SK Telecom updated its call platform ‘T Phone’ to ‘Aidot Phone’, adding a ‘Spam & Phishing Detection’ feature that allows AI to detect and block reported numbers as well as recent spam and voice phishing suspicious numbers in real time. LG Uplus is also set to release an AI agent ‘ixi-O’ this month that features voice phishing detection that provides alerts in real time.”,
,
, “An industry representative said, ‘With the convergence of the Financial Supervisory Service’s database of voice phishing criminals’ voices, known as ‘The Voice’, with telecom companies’ AI technology, it has become possible to detect crimes not only through specific numbers but also through voices. We hope that the commercialization of services, such as AI agents and spam blocker apps, will help prevent voice phishing crimes.'”
