Question 10/17

​Identity management and telebiometrics architecture and mechanisms

(Continuation Questions 9/17 and 10/17)

Motivation
Biometrics is gaining acceptance in applications performing but not limited to identity verification such as e-commerce, tele-medicine, and e-health. Biometric application systems present various challenges related to operational and technical data protection, reliability, and security of biometric data for biosafety and biosecurity applications.

Server-side biometric authentication becomes more complicated and demanding when biometric authentication is adopted in an open network environment. Telecommunication applications (such as telebiometrics) using mobile terminals and Internet services demand authentication methods to provide high security and friendly usage. It is necessary to specify requirements for the usage of telebiometric data in a manner that is safe, secure and with enhanced operational and data protection.
Identity management (IdM) is the management of the life cycle and use (creation, maintenance, utilization, and revocation) of credentials, identifiers, attributes, and patterns by which entities (e.g. service providers, end-user, organizations, network devices, applications, and services) are known with appropriate levels of trust. Depending on the context, multiple identities may exist for a single entity at differing security requirements, and at multiple locations. Depending on the identity model, the control over identities can be centralized or decentralized or a combination of both. In public networks, IdM supports trusted information exchange between authorized entities. The exchange is based on assertion of identities across distributed systems from multiple service providers. The exchange can also be based on various service environments such as cloud and 5G. IdM also improves the protection of private information and based on the trust model can ensure that only authorized information is disseminated.
IdM is a key component of telecommunications/ICT networks, services, and products because it supports establishing and maintaining trusted communications. In addition to performing authentication of an entity’s identity, it also permits authorization of access based on privileges. It also supports the change of privileges when an entity’s role changes delegation, and other identity-based services.
IdM is a critical component in managing network security because it improves assurance for the nomadic, on-demand access to networks and services that end-users expect. Along with other defensive mechanisms, IdM helps to prevent fraud and identity theft and thereby increases users’ confidence that transactions are secure and reliable. As IdM works in a mutual manner, this increased level of trust applies equally to both the end user and service provider.
National/regional specific IdM specifications and solutions will exist and continue to evolve. Setup a foundation upon which harmonize solutions could be implemented is important. In addition to the study of telebiometric, this Question is dedicated to the vision setting and the coordination and organization of the entire range of IdM activities within ITU-T. A top-down approach to the IdM will be used with collaboration with other study groups and other standards development organizations (SDOs). It is recognized that other Questions will be involved in specific aspects of IdM, i.e. protocols, requirements, network device identifiers, etc.
