What is the function of an Identity Management System (IDMS)?

• A. An Identity Message System (IDMS) is a system that enrolls an applicant biometrically and tracks that identity in one system integrated with multiple independent systems where the same identity must be verified and used.
• B. A system that stores only photographs of applicants.
• C. A payroll management tool.
• D. A system for scheduling shifts.

Answer: (A)

Identity Management System coordinates and sustains a single, verifiable identity for a person across multiple independent systems. By enrolling someone biometrically, the system creates a unique biometric reference tied to that person and keeps track of that identity in a centralized way so it can be verified and used wherever authentication is needed. This allows consistent provisioning, access control, and audit trails across diverse applications and services—doors, IT logins, HR records, and more—so the same person is recognized everywhere in a coordinated manner, and permissions can be managed lifecycle-wise (creation, updates, deprovisioning).

Storing only photographs or using a system for payroll or scheduling doesn’t capture the cross-system identity management function. Photos don’t provide the biometric enrollment and ongoing identity tracking across apps, and payroll or scheduling tools handle separate business processes rather than centralized identity provisioning and verification.
