Sensor-Enhanced Authentication Token for Dynamic Identity Management

sensor, authentication, identity management, security communication protocol Identity management as a component in applications is increasing in importance. Many applications need to manage user identities in a dynamic way because threats or conditions under which the application is to be used can change rapidly. We describe a new system for dynamic identity management that can accommodate changes in authentication requirements based on context. Central to this system is a user neutral, context aware token that is worn by a person seeking access to resources or assets. The token device stores information related to the wearer’s security permissions including biometric data. A unique feature of this system is the use of user attachment sensors that detect if the token has been removed from the wearer’s possession, and return it to its neutral state. Using this token, we explore security in context aware and dynamic systems, and give details from a prototype system.
