Metaは、WhatsAppのAIアシスタント向けの新モード「シークレットチャット」を導入します。この機能により、Meta社自身もユーザーの会話内容にアクセスできなくなります。本機能はエンドツーエンド暗号化とプライベート処理技術を採用しており、今後数ヶ月かけて順次利用可能になる予定です。
Metaは水曜日にこの機能を発表しました。同社によると、シークレットチャットでやり取りされるメッセージは、第三者が一切アクセスできない安全な環境下で処理されます。会話履歴は保存されずデフォルトで消去されるため、MetaのAIモデルの学習には利用されません。
X（旧Twitter）での初期の反応では、安全な処理やメッセージの自動消去といったWhatsAppのMeta AI向けプライバシー強化機能が評価されています。一方で、信頼性に懐疑的な意見や、もっと早く導入されるべきだったという声も上がっています。
