The Ministry of Science and ICT presented AI-based detection and alert services by Samsung Electronics and the three telecom companies as a public-private cooperation outcome to reduce voice phishing damage.
The ministry said on the 12th that these services help raise user awareness by detecting warning signs early in actual call situations.
This feature analyzes call content in real time and notifies users of the risk level step by step. It is available on the Samsung Electronics Phone app, SK Telecom adot Phone, KT Whowho, and LG Uplus ixi-O. The key is that analysis processing is performed by the AI inside the smartphone device, not an external server, reducing concerns about personal information leaks.
Samsung Electronics provides voice phishing suspicion call alerts on Galaxy devices with One UI 8.0 or later. During calls from unknown numbers, it displays two-stage alerts—suspicion and detection warnings. SK Telecom comprehensively analyzes conversation patterns and issues warnings via pop-ups, alert sounds, and vibration, categorized as suspicion or risk, and it is also set to launch a criminal voice detection feature.
KT Whowho combines real-time context detection, speaker recognition, and deep voice detection. Android users can use it regardless of carrier, and KT will push within the year to lighten the AI engine for low-spec devices and shift to a single app. LG Uplus ixi-O applies both anti-deep voice and criminal voiceprint matching to issue immediate warnings during suspicious calls.
The ministry urged users to end the call immediately upon receiving a suspicious call and to simultaneously verify with family or acquaintances and recheck through official channels of financial institutions. It also said it will continue to support technology advancement by manufacturers and telecom companies, and, if unavoidable personal information processing accompanies technology development for the public interest, strengthen institutional backing through regulatory exemptions.
