【摘要】 提出了一种数字内容借(租)阅模型及其实施框架。该模型可实现数字内容的传统借(租)阅模型,也易于产生新的数字内容使用模型,具有较强的灵活性。模型的主要协议及其功能由许可证规则实现,易于借阅策略的更新修改,也使客户端软件代码精简短小,易于高可信验证。说明和示例了模型的协议、实施机制和实施方法,并与相关方法进行了对比。更多还原

【Abstract】 A lending(renting) model and its implementation framework of digital content were presented.The model not only can implement traditional lending(renting) models,but also can realize many new using models,which brings a strong flexibility to the model.The main protocols and functions of the model were implemented by license rules that make the update of lending policies easier and code shorter,and can satisfy the requirements of high assurance.The protocol,implementation meachnism and method of the model were explained and exampled.Finally,a comparative analysis with current methods was showed.更多还原
