面對 AI 生成圖同修圖愈來愈難分,Apple Reference Image 想解決嘅問題唔係靠肉眼估張相「似唔似真」,而係留低一條由拍攝一刻開始嘅加密證據鏈。
呢項功能只適用於 iPhone 18 Pro 及 iPhone 18 Pro Max,而且要由用戶自行開啟「參考模式」(Reference mode)。拍攝後,除咗平日可編輯、可分享嘅相片,系統仲會保留一份獨立嘅「參考影像」,角色近似數碼底片,方便同主相片對照。36
關鍵在於:由感光元件開始簽署
Apple 表示,iPhone 18 Pro 主相機嘅新感光元件可為每一個捕捉到嘅像素作數碼簽署。當用戶以參考模式影相,主相機會同時記錄已簽署嘅感光元件資料,而唔係等一般影像處理完成之後先附加來源資訊。312
根據 Apple 相關技術說明報道,感光元件會進入專用參考模式,在拍攝後即時對像素資料作加密簽署,並連同感光元件中產生嘅中繼資料形成受保護嘅「安全數碼底片」。設計目的係令之後對像素、受保護拍攝資料或認證輸出作出嘅改動變得可被偵測。1726
