We have deployed MOSIP v1.2.0.1 on-prem. Could you please clarify if Demographic Deduplication and Verification Client needs to be developed separately and please share any documentations or references required for the development if any.
Demographic de-duplication logic is already implemented in the Registration Processor module at the registration-processor-demo-dedupe-stage. When a demographic match is detected, this stage communicates with the ABIS through the ABIS Handler and ABIS Middleware stages to perform biometric de-duplication on the corresponding gallery data (i.e., the demo-dedupe matched records).
