Ongoing concerns have been raised over the effectiveness of information technology products and systems in maintaining privacy protection for sensitive data. The aim is to ensure that sensitive health information can be adequately protected yet still be accessible only to those that "need-to-know". To achieve this and ensure sustainability over the longer term, it is advocated that an alternative, stable and secure system architecture is required. This paper considers the adoption of a model targeted at health information that provides much higher degrees of protection. A purpose built demonstrator that was developed based on enterprise-level systems software products is detailed. The long term aim is to provide a viable solution by utilizing contemporary, commercially supported operating system and allied software. The advantages and limitations in its application with a medical database are discussed. The future needs in terms of research, software development and changes in organizational policy for healthcare providers, are outlined.
