NAADI: National Analytical Platform for Dealing with Intelligent Tracing, Tracking and Containment of COVID19 Pandemic

Under the SAMHAR-COVID19 Program of C-DAC, we have developed a platform called NAADI: National Analytical Platform for Dealing with Intelligent Tracing, Tracking and Containment of COVID-19 for infected persons and quarantined people. NAADI offers along with Two Mobile applications namely, 112⁺⁺ India App for Citizens and nCov Satark App for Health Professionals and Government Decision makers. NAADI also offers Customized Asset Management System of C-DAC for COVID19.

This platform has extensively used the expertise garnered by three successful platforms developed by C-DAC; Emergency Response Support System (ERSS),e-Sanjeevni & Mercury: Tele-medicine Solution and "Suraksha Mitr" Vehicle Tracking System (VTS). ERSS is an integrated system that provides a common platform to receive distress calls in the form of voice, message, email, panic signal etc. through a Single Number '112'. C-DAC has carried out Nation-wide deployment of '112 system' and around 5.5 Lakh downloads of '112 India App' by users have facilitated saving many lives and persons in distress. e-Sanjeevni and Mercury are already deployed in Ten States. VTS is also a well proven system for online tracing and tracking of vehicles.

NAADI platform offers Comprehensive Multi-Level, Multi-modal and Multi-lingual Tracing, Tracking and Containment of COVID-19 Quarantined/Under Observation/Infected Individuals.

NAADI Provides:

• Automatic Data collection and Analytics
• Offers Customized Asset Management System of C-DAC for COVID19
• Big data Ingestion Platform that can take in Multi-Modal Location data
• Data Security & Privacy Preserving methods through Encryption and Anonymization
• Intelligent Real-time Data Analysis and Visualization for Proactive Decisions
• National-level, State-level, District level and Individual level Granularity
• Scalable Platform powered by High-Performance Computing Infrastructure

nCov-Satark App (Powered by C-DAC's NAADI Platform) for Health Agencies

• Role based access control and workflow
• Authentic & Automatic Data Extraction & Analysis of Past travel history of affected Individuals
• Violation detection based on Location based tracking (GPS)of movements of quarantined/affected individuals
• Tracking individuals based on Call Data Records (CDR) and (IPDR) beyond location based services
• Proactive Alerts related to Health professionals

112⁺⁺ India App for Citizens

• Triggering Medical Emergency and Response.
• 'SHOUT' feature for registered Health Worker close to the victim for immediate assistance.
• Remote diagnosis by Health Expert based on Spatio-temporal data analysis.
• Automatic Proactive alerts to avoid COVID-19 affected locations precisely.
• Finer level tracing through Bluetooth for real-time analysis to aid users know about encounters and interactions with affected individuals.
• Spatio-temporal analysis of user movements in reference to COVID-19 affected areas

Ops Logistics System

• Resource Management of COVID19 related resources like Hospital, Hospital Beds, ICUs, Ventilators, Drugs, Ambulances etc
• National Level, State-level, District-level and Taluka-level Multi-level views
• Seamless Data porting from various formats (csv, xls etc)
• Dynamic addition of resources and adding availability status
• Intuitive Visualization and Analysis

It is gratifying to note that a few applications are being developed and are being launched as a quick response by many agencies. The tool developed by C-DAC is comprehensive connecting citizens, health agencies and Government Decision makers. It provides the following features in addition to the ones provided by these applications which will complement and strengthen our country's efforts.

• 'SHOUT' feature for registered Health Worker close to the victim for immediate assistance
• Real-time Field level data through closed loop mechanisms
• Emergency Response and Incident Handling features for triggering actions at field level
• Call Data Records (CDR) & (IPDR) beyond location based services and for coarse level granularity.
• Quarantine Violation detection based on Location based tracking (GPS) of movements of quarantined/affected individuals.
• Customized Asset Management Solution for COVID19
• Finer-level granularity of tracing movements and encounters based on Bluetooth short ranges.
• HPC based Scalable Platform for National Level Data Collection and Analytics (using Data Science).

It is our strong conviction that this NAADI platform will prove to be a giant leap in our country's efforts to combat COVID19 Pandemic.
