QR Code是目前最為流行之快速的資訊及簡便的文字傳輸與連結的方法,加上智慧型手持式裝置的普及,利用有安裝QR Code解碼器的手持式裝置,就可快速瀏覽其資訊。QR Code的設計雖然無法直接使用肉眼判斷出編碼的內容是什麼,但因為其產生容易,其中所包含的資料與連結並無安全的機制加以保護,因此QR Code包含的資料可能會遭到竄改。使用者利用QR Code擷取資訊後,可能連結到與內容不相關的地方或病毒連結,造成使用者的損失。因此本論文提出基於非對稱性安全機制的QR Code影片播放系統架構,搭配目前因應的影片分級制度結合存取控制,讓使用者可以在安全的情況下使用,達到具有安全性與存取控制的行動影音應用。
QR Code is the most popular media for deliver information with data embedded in the square symbol. And the intelligent mobile device is popular, by using the mobile device with QR Code decoder, users could get the information quickly. Although the information embedded in the QR Code is not recognized by users' eyes easily. But the QR Code is produced easily and the embedded data is not secure so that the data would guide user to other places that users do not expect. Therefore, in this paper, we proposed the design and implementation of QR Code-based video streaming system with asymmetric cryptography and access control mechanism to provide secure and valid access of multimedia content.
