The Aadhaar card is a very important document. An Aadhaar card holds the biometric and demographic data of an individual. This data is valuable and hence, there is a possibility of misuse.

For protecting the data of the people, the Unique Identification Authority of India has developed a new feature called Aadhaar Authentication History. This feature lets you check online when and who has used your Aadhaar number.

Aadhaar Authentication

Aadhaar authentication is a process by which the Aadhaar details of a person (number, demographic information or biometric information) is verified and cross-checked by the Central Identities Data Repository (CIDR). This is usually conducted in case a bank, a financial institution, government agency requests for such information.

The different types of authentication methods are

Demographic Authentication

In this method, the Aadhaar number and demographic information of the Aadhaar number holder is cross-checked and verified with the demographic information of the Aadhaar number holder in the records held/registered by CIDR.

OTP or One Time Pin based Authentication

In this method, an OTP with limited validity is sent to the registered phone number/email id of the Aadhaar number holder. The Aadhaar number holder is required to provide the OTP along with the Aadhaar card number to the authority.

Biometric-based Authentication

In this method, the Aadhaar number and biometric information submitted by an Aadhaar number holder are matched with the biometric information of the said Aadhaar number holder registered in the CIDR. This can be fingerprint-based or iris-based authentication or other biometric modalities as registered in the CIDR.

Multi-factor Authentication

This is a combination of two or more methods mentioned above.
