Japanese telecom giant NTT Docomo has developed an artificial intelligence (AI) system capable of identifying fraudulent telephone calls. The innovative technology aims to combat the increasing menace of scam calls, enhancing user security. The specific release date or rollout plan hasn't been disclosed, but the move underscores Docomo's commitment to maintaining the integrity of Japan's telecommunications network.

Scam phone calls, or "ore-ore sagi," are a serious issue in Japan, with the average loss per case reaching an all-time high in recent years. The public is deeply concerned about these scams, often targeting the elderly. Docomo's initiative aligns with social values of accountability and the safeguarding of vulnerable citizens.

In the US or EU, similar initiatives are often pursued by individual telecom companies or in some cases mandated by regulatory bodies. However, the widespread adoption of such AI systems across all telecom service providers is not yet universal.
