Title: Dynamic Rights Reallocation In Social Networks
Author(s): Adnan Ahmad, Brian Whitworth, Lech Janczewski
Reference: pp185-194
Keywords: Socio-technical, social networks
Abstract: Access control, as part of every software system, has evolved as computing has evolved. Its original aim was to limit unauthorized access for centralized systems, but the rise of online social networks like Facebook has changed that. Now each person wants to control who sees photos or makes comments on their local wall by making and unmaking friends, i.e. dynamic, distributed rights control. Social networks already have access control, but there is currently no agreed logical model for their rights, no consistent scheme for allocating and re-allocating permissions to create, edit, delete and view social objects and entities. A socio-technical approach based on social and technical requirements can give the basics of a model. Various rights re-allocations like transfer, delegate, divide and multiply are explored. It suggests a theoretical base for access control beyond its security parent.
