- Abstract
- Many researchers have developed frameworks capable of handling context information and able to be adapted and used by any Web service. However, no research has been conducted on the systematic analysis of existing frameworks. This paper analyses the Context Framework, an example of existing frameworks, using a Petri net, and analyzing the advantages and disadvantages of it. Then, a Petri net model is introduced, with disadvantages removed. Based on the model, a new framework is presented. The proposed PAWS(Privacy Aware Web Services) framework provides extension to context management and communicates flexible context information for every session. The proposed framework can solve overhead problems of context in SOAP messages. It also protects user privacy according to user preferences. © 2007 IEEE.
