1 No Purpose – No Data: Goal-Oriented Access Control for Ambient Assisted Living Università delgi Studi di Trento Fabio Massacci, Viet Hung Nguyen, Ayda Saidane This work is partial supported by EU committee with grant of PrimeLife/IFIP 2009 Summer School, 7 th – 11 th Sep, 2009, Nice, France

2 Università degli Studi di TrentoGlance Ambient Assisted Living (AAL) Demo Goal-oriented Role Based Access Control Summary 5/2/20142Goal Oriented RBAC

3 Università degli Studi di Trento Ambient Assisted Living (AAL) AAL is a home environment enhanced with embedded technologies –Cameras –Oximeter –Smart T-shirt –… 35/2/2014Goal Oriented RBAC

4 Università degli Studi di Trento Concrete scenario We do not want our medical data out unless it serves some purposes: privacy requirement We want to be monitored even if one of monitor devices fails: dependability requirement 45/2/2014Goal Oriented RBAC MERC

10 Università degli Studi di Trento Goal-Oriented Role-Based Access Control Organizational model –Privacy goals E.g., MERC wants to check out medical data for monitoring purpose –Critical goals E.g., Access monitor devices data in an emergency –Normal goals Access control strategies –Privacy setting Privacy resources are accessed by authorized agents if and only if it is needed –Dependability setting The derived permissions of all sub goals resources are released once the user is authorized to fulfill the top goal –Normal setting 105/2/2014Goal Oriented RBAC
