Digital Identity corresponds to the electronic information associated generally with an individual in a particular identity system. This is used by online service providers to authenticate and authorize users for services protected by access policies. Having good identity systems can enable individuals to use effectively and extensively electronic transactions in a secure yet privacy preserving manner. In order to match the above purpose, this paper introduces an identity scenario, a user-centric identity management, in terms of VID -- Virtual Identity, which concept is designed to protect a user?s privacy and secure communication data, which contemplates the multitude of identities and roles we take on each time we turn on our computer, mobile phone or PDA.. Simultaneously, the associated identity management system with its related infrastructure is described. A key component, the ID broker, of the proposed infrastructure is also detailed including some interfaces and their related components. Furthermore, a method that allows a user to manage his/her service via the VID is introduced.
