Aadhaar Bridge is an online service that makes it easy for companies to access the Aadhaar National ID system - hosted by the UID Authority of India (“UIDAI”). In order to provide this service Khosla Labs is a registered AUA(Authentication User Agency) with the UIDAI.
Aadhaar Bridge offers services through online APIs for conducting Authentication and eSign transactions.
The Aadhaar Authentication or Auth transaction is similar to userid and password being used while logging into say gmail. It is a person's way of proving who she or he is. The Aadhaar Authentication API only returns a YES/NO response for a verification request.
|Authentication type||Information used for Authentication||Type of Verification||Level of Assurance|
|Biometric||Fingerprint or Iris scan||What I Am||High|
|OTP||Uses One Time Password||What I Have||Medium|
|Demographic||Name, Gender, Address, Date of Birth||What I Know||Low|
The UIDAI provides for both fingerprint and iris biometric authentication. The UIDAI has also recommended standards for fingerprint and iris sensors that can be used for Auth. User agencies need to procure STQC Compliant sensors in order to use the Aadhaar online services.
We support all biometric sensors/devices certified by Aadhaar. List of Certified Aadhaar devices here
