Abstract
Creating an online identity via a username/password does not provide the ability to establish trust with other systems in order to get access to unauthorized information in a time-critical situation. Trust is the ability of two entities to believe one another at some level, so that they can interact in a secure manner, e.g., a physician at one hospital may need to obtain medical data on a patient from another hospital to treat a patient, facilitated if there is a trusted relationship. This chapter explores adaptive trust negotiation that obtains near real-time permission to access a system to which a user has never previously been authorized to, so that the system receiving the request can adjust its security policies depending on the attributes that the requester possesses. To accomplish this, a set of interacting systems (e.g., from different hospitals) can be augmented with identity management and adaptive trust negotiation to create a means where multiple disparate systems can make informed and dynamic security decisions about users relative to their defined security policies.
