由於網路科技的發達，雲端技術的應用也日趨增加。如：政府單位、私人企業及律師事務所等。各種不同的單位都可以把自身的資料儲存在雲端上面。使用雲端的好處除了可以在各種不同的地方使用同一份資料，還可以使多人共同編輯一份資料。雲端發展快速的同時也伴隨著安全性的問題，假設我們放在雲端上的資料可能被別人竊取、消失、或者被提供雲端服務的公司所洩漏，是否可以提出證據證明有發生過上述狀況？本實驗室過去研究提出一個方法來解決此問題，製作出了可以成為有效法律證據的電子證據。但該方法的證據都必須等到一段時間之後才能做稽核的動作，如果資料處理時發生錯誤必須等到稽核的時候才會發現。於是本研究把上述技術再加入即時稽核（Real-time Auditing），把過去在特定時間才能做稽核的問題解決。
