210/21/2015 META ACCESS MANAGEMENT SYSTEM Problem Statement ARP Administration (ShARPE) ARP Administration (ShARPE) ARP administrators need a ‘zero effort’ approach to implementing an access agreement with a SP – setting up site and group ARPs to supply required attributes. ARP administrators need a ‘zero effort’ approach to implementing an access agreement with a SP – setting up site and group ARPs to supply required attributes. User Privacy Control (Autograph) User Privacy Control (Autograph) There is a ‘real world’ requirement for privacy management, for end-user control of release of privacy sensitive attributes.
