UCL (UPDATE CLIENT LITE):
Update Client Lite (UCL) - Phase 1 application helps citizens, who are already enrolled
under Aadhaar, update either demographic or biometric information like:
• Email Id
• Mobile number
• Information Sharing Consent
It is equally important for the citizen to update the central repository to avail the Aadhaar
benefits. Update process is required to enable the citizen to request for updates in the system.
The UCL allows updates only on demographic details. For biometric details update, the
resident should visit an enrolment centre where the Standard Update Client and necessary
infrastructure is available.
The biometric data of user is expected to identify a user uniquely and is not changed
naturally for a long period of time, whereas the demographic details can change multiple
times without any hard conditions. It is, therefore, expected that residents will have
to update their demographic data in the central repository much frequently than the
biometric data. There is a need for large-scale deployment of update centers to cater to
the needs of demographic updates. These updates are not as sensitive as the biometric
updates from security and identity perspective and hence certainly have different need
from authentication measures perspective. Even within demographic details, email
address, mobile number and PIN are the fields that do not need any verification or proof
apart from resident authentication and hence can be updated instantly in an online mode.
UPDATE PROCESS USING UCL:
1. It allows the resident to update the demographic details after the resident has been
allotted an Aadhaar number.
2. Accepts the details as requested by the resident, authenticates the details with resident’s
single fingerprint biometric and sends it to the server to be updated in the central repository.
3. It updates the details and generates a print receipt bearing the changes which have
been requested by the resident.
