行動商務之發展性日益提高，行動交易越來越普遍，在任何型態行業都有發揮的空間在本論文中以電子票券的交易模式建構出運用視覺化加密法及時間戳協定的行動電子票券交易流程機制並以旅遊業為例，新的交易協定流程中，利用VSS技術加密的票券加入時間戳的管理概念，將票券以視覺式加密產生影像票券後拆成二份，僅先將前一半票券傳送至使用者的行動裝置裡，於票券時間戳到達時傳送後一半票券結合還原由驗證中心驗票，減少驗票流程與時間，增加票券實用性，時間戳的管理概念使得票券本身的加密及驗證達到無線環境中儲存與處理能力低及傳輸慢種種限制與要求，利用視覺式加密系統產生的票券可以成為安全且快速的交易憑證，在本管理系統的實現上我們以Web-based票券管理系統加入時間戳的管理概念。並加入旅遊者信用制度，增加業者與旅客之間的互動性，維護客戶與業者權益的功能。提供一個安全且快速的交易憑證。

Mobile commerce (M-COM) is becoming increasingly important in our life. We find the e-ticket is a popular way to implement the m-com. In order to solve some authentication and transaction drawbacks; we proposed a VSS (Visual Secret Sharing) ticket with time-stamp protocol on mobile environment─take travel industry for example. The VSS encrypt tech separate the ticket into two parts; one part of the ticket sends to user after he purchased. The other part ticket will be send to user when the time-stamp reached. The time-stamp protocol can provide a secure and fast verification. Control the tickets status can solve the mobile device and the e-ticket exist problem. In our environment, we offer lightweight load for mobile device and a simple identification work for merchant. It is a secure and verification fast mobile environment.
