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.
