Abstract [en]

This paper presents a secure framework for building personal assistants in a web browser environment. These assistants are personal computer programs, working on the behalf of their user. Around a minimal core of system resources, users are free to bring together the components of choice to form their personal assistants.

While moving around in physical and virtual space, other small computer programs, called guides, can be loaded into the system. Novel, personal services can be created by combining the guide’s understanding of the environment with the personal assistant’s user-specific knowledge.

To prevent multiple guides from overloading the user, all interactions with the user have to go via a conversation manager. A nightclub-style bouncer administers security, controlling the credentials of guides wanting to enter the system. The use of Internal proxies between components not trusting each other enables malicious or faulty code to be thrown out at any time.

As a test of concept, a prototype tour guide system for the Exploratory Science Centre in Bristol has been implemented, using Java in Netscape Navigator.
