SecuGen Hamster Pro 20 Installation and RD Service for Aadhaar Based Authentication

The Government of India has ambitiously pursued the world’s largest biometric collection campaign – Aadhaar, in order to give its citizens and residents a taste of biometric authentication and of course, to improve access to the government services. The country has also been in the process of replacing the mode of authentication for government services with Aadhaar based biometric authentication. Some of these services even allow Aadhaar authentication done remotely, i.e. via the internet.

This development has resulted in a big relief for the Indians spread across the world (such as NRIs), who otherwise had to travel to India for physical authentication to avail services like pension scheme (Jeevan Praman) and many other government services.

To ensure that Aadhaar based authentication stays as secure as its physical counterpart and to eliminate any possibility of manipulation to (e.g. use of fake or stored biometric identity), UIDAI has introduced RD service. UIDAI (Unique Identification Authority of India) is the government agency that regulates the Aadhaar based authentication for private as well as government organizations.

SecuGen registered device (RD) service

SecuGen registered device service a.k.a. Secugen RD service is the process to convert an Aadhaar compatible biometric hardware (e.g. newly purchased SecuGen Hamster Pro 20 / HU20 fingerprint reader) into a registered biometric device to make it usable for Aadhaar based authentication.

Aadhaar based authentication replaces manual or physical process of identity authentication with an online system, in which Aadhaar number and biometrics along with other details are submitted to Aadhaar system for authentication via the internet. RD service enables your Aadhaar compatible biometric device to perform secure transaction with Aadhaar system. According to the UIDAI, RD service has to be facilitated by the device manufacturer.

Registering your Aadhaar compatible biometric device with RD service eliminates any possibility of using a third party application to provide stored biometrics for user authentication. It is achieved by signing biometric data within the device using the provider key, and forming an encrypted PID block, which ensure it is captured live and not with stored biometrics. Registered device have a unique identifier, which allows traceability, analytics and fraud management.

RD service ensures that the biometric sample is captured from a real person and not by other means. This feature is in line with the government’s objectives to ensure that a user’s stored biometrics is not used by someone else for availing any government service.

RD service provider signs every biometric scan before sending it to the host application. These scans are time stamped and encrypted in order to ensure security. As per UIDAI guidelines, it is mandatory to use registered devices for Aadhaar based biometric authentication to avail government services such as Pension Scheme (Jeevan Praman), eKYC, Rental Agreement, Property Sale and many other services.

RD service architecture

SecuGen RD service is designed in a way that it creates a secure environment to protect the user biometrics from any potential manipulation. The secure environment created by the RD service architecture ensures that the government services can only be accessed by authorized individuals. It also protects user biometrics form any potential misuse by cybercriminals.

rd-service-architectureImage: RD service architecture with a SecuGen registered device. A: RD Service API; B: SecuGen Management Server Protocol / API; C: AUA Protocol / API; D: UIDAI Authentication API 2.0; E: UIDAI Registration API.
Following is the sequence of typical operations using the registered devices:
  1. AUA/Sub-AUA provided application starts in host machine.
  2. Application does a RD Service discovery.
  3. When ready for the biometric capture, application connects the RD Service to initiate the PID creation (which contains digitally signed and encrypted biometrics).
  4. When the RD Service detects a good capture, it does necessary processing/extraction, creates the signed biometric record (FMR, FIR, IIR, FID), forms the encrypted PID block, and give the encrypted PID block back to application along with other details including the device Info.
  5. Application obtains the encrypted PID block along with other information from the RD Service for calling Aadhaar authentication (see Aadhaar Authentication API 2.0 specification for details).

“RD Service” refers to device provider’s registered devices service that allows capture and processing of biometrics. This RD Service then returns encrypted PID block containing signed biometrics (using device private key within the registered devices secure zone) back to the calling application.

All registered devices providers MUST provide certified RD Service for various supporting operating systems so that applications can integrate easily in a secure and standard way without needing to embed any special software within applications. Providers also must ensure that RD service can be run under separate user not needing root/admin privileges.

Registered devices securely sign the biometric data, form the encrypted PID block within the RD Service and give it back to application for use within Aadhaar authentication.

Registered devices ensure the following:
  1. There should be no mechanism for any external program to provide stored biometrics and get it signed and encrypted.
  2. There should be no mechanism for external program/probe to obtain device private key used for signing the biometrics.

It is important to note that it is in device provider’s interest to ensure the above two items are implemented securely since any compromise on these will result in fraudulent activities signed using the device provider key. As per IT Act it is essential for the key owners (device provider) to protect the signature key and take responsibility for any compromise.

What’s next?

Now as your SecuGen biometric device is all set to take your Aadhaar biometric authentication to the internet, next is what you want to do with it. You can use it for all the government services that allow online identity authentication with Aadhaar.
