A first digital identification document is transmitted from an identification authority to a mobile device of an identified individual. This first digital identification document is digitally signed and includes a set of attributes about the identified individual. In the same manner, a second digital identification document is also transmitted to the identified individual's mobile device. The second digital identification document is also digitally signed but includes a different set of attributes about the identified individual. The identified individual is then confronted by a series of challengers, wherein each challenger requires a different amount of information about the identified individual. Based on the identity of each challenger, the identified individual selects an appropriate identification document and transmits it to the applicable challenger's device. The challenger is then able to confirm both the information he needs about the identified individual and the validity of the identification document that he receives.

Using multiple digital identification documents to control information disclosure

Identity fraud is a serious problem which can be used to conduct crimes such as economic fraud, human trafficking and terrorism. Many organizations have pointed out challenges in performing identity control, and a more operable framework for identity proofing and verification is desired in many practical applications. Although there are several guidelines and international standardization activities available on identity proofing and verification routines, complexity and variation among these frameworks can make them complicated to interpret and understand and thus little operable, particularly for smaller organizations performing identity control. Against the increasing trend of identity fraud worldwide, this paper proposes an Evidence of Identity (EoI) evaluation system design aiming at operationalizing requirements to evidence of identities in ID proofing and verification processes. The suggested system is designed to be included in a computer application, allowing easy use by front-desk officers.

Towards an Operable Evaluation System for Evidence of Identity

This paper proposed a model of 7-Phase Personal Identity Management Cycle which can capture important actors and events that happen around the management issues of a personal identity. This paper explained the purpose of each phase, the actors and the conditions involved in transition between phases. Examples and scenarios are also provided to give illustrations how this model can be used to address different issues in Identity Fraud.
