How to control the access and usage of digital resources is one of the most important issues in computer security nowadays. Among them, how to control the resources when they have been passed to the client-side is a research hot spot. The Usage Control Model (UCON) has been proposed to solve this problem. In this research, we focus on one core component of the UCON model, the obligation. We propose a new obligation model to solve the problems the current ones can not deal with, especially for post-obligation. We also offer two testing scenarios, propose an architecture for a prototype based on the proposed model and apply the scenarios to the prototype architecture for proof-of-concept.
