From the Aadhaar Registered Device Specification: “The Unique Identification Authority of India (UIDAI) has been created, with the mandate of providing a Unique Identity (Aadhaar) to all Indian residents. The UIDAI provides online authentication using demographic and biometric data.”
What is a Registered Device?
Registered Devices ensure that captured biometrics are authentic and fresh (live captures, not stored). Registered devices have unique identifiers so that each capture can be traced back to a device. Captured biometrics are signed and encrypted.
What are Level-0 and Level-1 Registered Devices?

Level-0 Registered Devices may make use of the host operating system for feature extraction, signing, and encrypting the biometrics. On Level-1 Registered devices all sensitive operations (capture, feature extraction, signing and encrypting the biometric trait) are performed within a trusted execution environment.
