Android 在 Google Messages 中用 AI 识别诈骗者
Android is using AI to suss out scammers in Google Messages
Android 推出新的反诈防护功能，Google Messages 将在未来几周上线“增强保护”设置，调用云端 Gemini 模型评估陌生发件人对话中的诈骗意图。该模式需用户主动开启，分析期间数据加密并在专用安全空间处理，Google 自身也无法访问；同时用端侧 Gemini Nano 在打开前检查陌生 URL 的实时网页信号。Google 还宣布阻止应用开启呼叫转移并通知用户、在 Chrome 和 Android WebView 屏幕共享时自动隐藏敏感信息，Pixel 上的聊天通知诈骗检测将扩展到 Honor、Motorola、Oppo、OnePlus、Realme、Tecno、Vivo、Xiaomi 等设备，并计划今年晚些时候覆盖数亿用户。

Android is introducing new scam defense features that aim to make it easier for users to evade mobile fraud, including bolstered protection in Google Messages and additional safeguarding tools. Building on the Scam Detection feature in Google Messages, a new “enhanced protection” setting will be rolling out in the coming weeks that taps into cloud-based Gemini AI models to quickly evaluate a potential scammer’s intentions in conversations with an unrecognized sender.
“Scammers often disguise their true motives behind slow-burn conversations,” Google said in its update announcement . “This secure cloud analysis augments and extends our existing on-device detection, allowing us to identify novel and sophisticated attacks, actively uncovering and stopping abusers who try to hide their tracks.”
User data is encrypted during this AI analysis and “processed in a secure dedicated space” that Google (and anyone else besides the user) can’t access. The enhanced protection mode will be opt-in, and also uses on-device Gemini Nano AI to inspect real-time web signals in unfamiliar URLs sent to the user before they’re opened to determine if the links are malicious.
Additional security features announced today include blocking apps from enabling call forwarding, and notifying the user when someone attempts to do so, along with automatically concealing sensitive information while screen-sharing in Chrome and Android WebView. The scam detection feature for chat notifications Google introduced on Pixel phones last year is also expanding to devices from Honor, Motorola, Oppo, OnePlus, Realme, Tecno, Vivo, Xiaomi, and more. Google says it plans to bring it to “hundreds of millions of additional users later this year.”
