Android 为 Google Messages 推出 AI 反诈增强保护
Android is using AI to suss out scammers in Google Messages
- 1Android 推出新一波诈骗防御功能，Google Messages 将在数周内上线增强保护设置
- 2增强保护需用户主动开启，用云端 Gemini 模型分析陌生发件人对话，官方称可识别新型和复杂攻击
- 3端侧 Gemini Nano 在陌生链接打开前检查网页信号，另新增拦截呼叫转移和屏幕共享遮蔽敏感信息
- 4Pixel 聊天通知诈骗检测将扩展到 Honor、小米、Oppo 等品牌，官方计划年内覆盖数亿新增用户
Google 将诈骗检测从端侧推向云端大模型分析，并将其作为 Android 平台能力向多家手机厂商铺开。
- 影响：面向陌生用户的消息触达会被云端 AI 评估诈骗意图，正规短信通知存在被误判的可能；呼叫转移拦截与屏幕共享敏感信息遮蔽，会影响依赖这两类操作的远程支持和演示场景。
- 参考：可考虑梳理自有短信和消息触达的话术与链接形态，避免慢热式对话和可疑短链模式，降低被误判概率；值得让 IT 盘点依赖呼叫转移或屏幕共享的业务流程，评估新功能上线后的适配。
- 依据：Google 官方公告称云分析在加密的专用空间处理且其无法访问，功能为自愿开启，扩展计划年内覆盖数亿新增用户，均为官方口径，暂无独立验证。

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.”
