Layer Model and Algorithm of Organization Authorization Based on Position Network

After the RBAC model formalized in 1992 by David Ferraiolo and Rick Kuhn, the models of organization authorization have been developing fast. Among these models, the one based on position network will be used widely and has a prospective future. Algorithms for single-layer model and multi-layer model based on position network were cited in this article. Meanwhile an algorithm example was given at the end of this article.
