D3.9: Study on the Impact of Trusted Computing on Identity and Identity Management

Title: TYPES OF IDENTITY MANAGEMENT

Types of Identity Management

In the FIDIS-deliverable D3.1 three basic types of Identity Management Systems (IMS) were introduced (Bauer, Meints, Hansen 2005): 

1. Type 1: IMS for account management,
   implementing authentication, authorisation, and accounting

2. Type 2: IMS for profiling of user data by an organisation,
   e.g. detailed log files or data warehouses which support e.g., personalised services or the analysis of customer behaviour,

3. Type 3: IMS for user-controlled context-dependent role and pseudonym management. 

Implementations of IMS also may be of hybrid types combining different organisational structures and methods characterising the introduced types. Trusted Computing may play a role in all three types of IMS.
