臺灣博碩士論文加值系統

在今日，電視是一種十分廣泛的通訊媒體。不過，觀眾對於已編排固定的節目型態已不能滿足。因此，針對於上述的情況，就有人提出其他額外的影視服務出來。再者，網際網路在現在亦是十分地普及受歡迎，且能提供使用者許多資源及資訊。由此，可以知道，隨選視訊(Video-on-Demand)在未來勢必是一個趨勢。

話雖說如此，但是對於隨選視訊(Video-on-Demand)而言，仍是存在著許多問題。這第一個問題就是身分認證的問題。我想，應該沒有人會喜歡其被人偽冒身分、密碼及帳號被盜用的情形發生在他們身上。而第二個問題，就是付款問題。因為隨選視訊(Video-on-Demand)在將來必定會採用以量計價的方式來向消費者收取費用。可是，要用何種方式來計算，就是一個十分直得重視的問題。至此，就談到第三個問題，那就是針對所傳送的資料的保密性的問題。對於隨選視訊(Video-on-Demand)，我們希望能防止沒被授權的人在資料傳送的過程來截取影片，亦希望其能提供一能即時播放的性能。這對於隨選視訊(Video-on-Demand)尤其是重要。最後，我們希望能夠提供給消費者，無需記憶任何密碼的便利性。

在本論文中，我們提出一個隨選視訊(Video-on-Demand)的架構。它能夠將上述所提到的種種情況給有效地解決。換句話說，我們的系統能夠提供一個方便、安全及值得信賴的認證及動態付款機制。

Nowadays, television has become a widespread communications media. However, the television audiences are not satisfied at scheduled programming. Thus, additional video services are offered because of the condition mentioned as above. In addition, Internet is so prevalent that it can provide illimitable network resources for users to obtain extensive information. Video-on-Demand (VoD) will be the trends in the future.

But, there are a lot of problems on Video-on-Demand. The first problem is the authentication problem. I think none likes someone pretend to be him or her, steal his or her account number and password. The second problem is payment problem. It must charge consumers service fee for using the Video-on-Demand service according to the consumer’s quantity. And, how to calculate each consumer’s quantity is a serious problem, which needs to be considered. Next, the third problem is the encryption of transmission data. We need a secure and reliable communication method to transmit data. Besides, the method also can provide a real-time communication. It is very important to a Video-on-Demand service system. At last, if consumers don’t remember their password any more, it will be more convenient service to consumers.

In this thesis, we propose a Video-on-Demand service system. It can solve those problems mentioned as above efficiently. In other words, the proposed system in this thesis can provide a convenient and secure and reliable authentication and payment mechanism.
