Pter Bodorik current research interests:

• E-business is supported by numerous systems in which middleware plays an important role. To ensure that the middleware provides appropriate services to appropriate clients, we have developed a QoS framework, and a supporting tool-kit, for monitoring of middleware and its infrastructure in which it operates. We are studying models for middleware components that would enable us to predict their consumption of infrastructural resources and delays and hence to enable allocation of resources and balance the workload. Caching is one of the basic techniques to improve the response time of web-based systems. We are studying adaptation of caching techniques in Distributed DBs (DDBs) to the environment of middleware components supporting web-based applications. (Selected publications can be found here.)

• As the use of e-business proliferates, the issue of privacy gains in importance. We have developed an architecture, based on the P3P platform, that supports requirements for enhanced user-controlled privacy. Privacy management issues that are addressed include the identification of data repositories and their purposes, user agents and their roles and interactions, and the separation of persona profile information from user preference information.
