This study has been performed to investigate the problem of lack of security in hypermedia systems. This study was based on the architectural design of past and existing hypermedia systems. The Dexter Reference model was used as the basis for this research. As an extension of the model, a password-based security mechanism was designed. The design approach used was to examine various hypermedia systems comparing and contrasting their similarities and differences. Issues of security and design methods were discussed as a way to increase the security in hypermedia environments. The results of this research demonstrate that private information can be stored on hypermedia systems and made only accessible to authorized users. This refinement of the Dexter Reference model may have an impact upon the design and evaluation of current and future hypermedia systems.
