隨著無線網路、行動寬頻、新一代無線裝置之推出及付款環節電子化，藉由無線裝置購買數位內容成為一種更方便的購物模式。 鑒於數位內容產業結構改變，其收款模式並未隨之改變，數位內容創作者應在其所創作之數位內容被銷售時，立即收到利潤，藉由即時分配收益的做法，激勵數位內容創作者的創作動機，讓市場上數位內容品質更為優良，增進消費者購買的意願。 本研究在再改良先前立即分配收益機制之多重受款者研究下，利用電子代幣做為付款之工具，提出適合低運算效能之無線裝置之多重受款者交易協定，並藉由事前商家與數位內容創作者簽定的收益分配合約，在其數位內容被銷售同時，即時分配收益給所有參與交易的收款者，並激勵數位內容創作者的創作動機。 對於交易之公平性，本研究之交易協定利用預防機制及可信賴的第三方，確保所以參與交易成員的權益。 最後利用案例的方式解釋本研究中的安全性與交易公平性，與協定之時間複雜度與執行效能做分析，並將公平性透過正規驗證之檢驗，確保買賣雙方利用本研究提出之協定交易時，權益皆不會受損。 Due to the wireless broadband and new powerful mobile phone and mobile internet device entered to the market, electronic transactions of digital content through the mobile device become one of the popular new shopping models. However, the changing of digital content industry structure, digital content creators should get their revenue immediately when the digital content was sold. Apportion the revenue right away could motivate the authors’ motivation, too. It could make the authors create high quality digital content. We improve Lin and Liu’s payment system on efficiency for digital content transactions. Authors and merchant sign a revenue apportion contract before the digital content selling, and apportion the revenue to all the payees immediately when the digital content was sold. At last, we explain the payment security and fair exchange by case to ensure the safety of the transaction. And use FDR as a formal verification tool to examine the fair-exchange property of our proposed scheme.
