Title
¬A capability-based authorization model for the World-Wide Web : results from the second WWW user survey

Abstract
Existing authorization schemes for the WWW present a client administration problem when hyperlinked documents and contents are stored in different servers. Proposes a new distributed authorization model where information servers are grouped into authorization domains. User administration is simplified as only 1 server in the domain needs to know its potential clients. Extensions to the model provide support document and content migration and implementation of user groups. A prototype of the model was implemented over an existing WWW system
