The concept of context-dependent access control has emerged during the last years: Information about the state of a process model of a working environment is combined with general knowledge about a person to grant or revoke access to protected data. Being understood very well in principle, different problems arise when implementing context-dependent access control, in particular on an open network. This paper reports on context-dependent access control to support distributed clinical trials. Centrally stored data will be accessed from contributors to a clinical trial over the Internet. We present in this paper how context-dependent access control can be implemented on the Internet in a secure way, using Java Servlets to implement the access control and SSL to secure communication. Keywords: Workflow-support for clinical trials, telemedicine, context-dependent access controls, health information systems.
