<p dir="auto">新功能方面，Fraud Defense 引入了代理活动监控仪表板、可按风险评分与代理身份设置放行或拦截策略的策略引擎，以及一项专门针对 AI 自动化的&quot;抗 AI 挑战&quot;——当系统检测到可疑代理行为时，会向用户呈现二维码，要求使用移动设备扫码以证明真人在场，从而使大规模自动化欺诈在经济上失去可行性。谷歌表示，现有 reCAPTCHA 客户将自动成为 Fraud Defense 客户，无需迁移、无需任何操作，定价与现有站点密钥均保持不变。移动端验证方面，Android 设备需 Google Play Services 25.41.30 及以上版本，iOS/iPadOS 需 15.0 及以上版本。</p>
