泛在环境下数字信息资源的访问控制策略研究
The Access Control Strategy of Digital Information Resources in Ubiquitous Environment
摘要
Abstract
In connect with the requirements of dynamic access control of digital information resources, a watermark and role group based access control model with context (WRGBACC) is designed. Firstly, this paper introduced the concept and deficiency of existing access control model, then the main elements and formal definition of WRGBACC are discussed exhaustively. Lastly, the application framework and working flow of WRGBACC in a video service system are described. The analysis results show that WRGBACC can manage the au-thorities of users and trace the piracy dynamically and real-time.关键词
