Registration Processor

Overview

This repository contains source code and design documents for MOSIP Registration Processor which is the server-side module to manage ID lifecycle. The modules exposes API endpoints.

Overview of Registration Processor

The front end UI application called Registration Client is available in a separate repo here

Registration stages and pipeline

Staged architecture:

• Group 1 stages
  • Packet receiver
• Group 2 stages
  • Securezone notification
  • Quality classifier
  • Message sender
• Group 3 stages
  • ABIS handler
  • ABIS middleware
  • Bio dedupe
  • Manual adjudication
• Group 4 stages
  • Biometric authentication
  • Demo dedupe
• Group 5 stages
  • CMD validator
  • Operator validator
  • Supervisor validator
  • Introducer validator
  • Packet validator
• Group 6 stages
  • Packet uploader
  • Packet classifier
  • Verification
• Group 7 stages
  • UIN generator
  • Biometric extraction
  • Finalization
  • Credential requestor

The control and data flow in the stages is controlled by Workflow engine

Other services:

• Packet Server
• Registration status service
• Notification service
• Transaction service

Registration flows

An overview of various enrollment scenarios (or flows) is described in ID Lifecycle Management. Registration Processor recognises the following flows:

• New
• Update
• Child
• Correction
• Lost
• Activate/deactivate
• Reprint

The stage sequence against each flow refer here

Vertx

Vertx is a framework for stages. Stages run as Vertx.

Kafka

Regprocessor stages are connected with eventbus. MOSIP supports two types of eventbus:

• Vertx Eventbus
• Kafka (default) - provides persistence across restarts (more robust), throttling capacity, better debugging

Kafka offers certain advantages over Vertx eventbus hence it is recommended as the default eventbus mechanism. All events between stages pass through Kafka queues. There is a separate Kafka topic for each stage.

One of the power features is to enable throttling in the pipeline. See Throttling

Hazelcast

Distributed cache - for packetmanager

Build & run (for developers)

The project requires JDK 21.0.3 and mvn version 3.9.6

1. To build jars:

   $ cd registration
   $ mvn clean install 
   

2. To skip JUnit tests and Java Docs:

   $ mvn install -DskipTests=true -Dmaven.javadoc.skip=true
   

3. To build Docker for a service:

   $ cd <service folder>
   $ docker build -f Dockerfile
   

Deploy
