偽造網站複製原始網站進行相同商業行為，造成原始網站權益的損失，原始網站擁有者必須提出證據說明原始網站版權所有，打擊偽造網站侵權行為。本文提出ADAPT訊息嵌入方法，採用英文縮寫（Abbreviation）、製作日期（Date）、演算法則（Algorithm）、執行人員（Person）、運用工具（Tool）等5項訊息，組成原始擁有者唯一知悉有意義的24字元特殊訊息，透過One-Way Hash Function的運算，將藏有DIGEST秘密影像，利用視覺安全技術-秘密分享機制，以密鑰分散管理、降低風險的概念，分散至網頁圖片偽裝體。當出現偽造網站侵權爭議時，依循電腦鑑識採證程序確保證據力及證明力，並結合秘密分享機制還原秘密影像取出DIGEST值，藉由比對DIGEST值證明原始網站所有，亦可達成資安技術的機密性（Confidentiality）、完整性（Integrity）及可用性（Availability）要求。
