Aadhaar number is a random 12 digit number devoid of any intelligence. Person willing to enrol has to provide minimal demographic along with biometric information during the enrolment process. The Aadhaar enrolment process does not capture details like caste, religion, income, health, geography, etc This is achieved through the process of demographic and biometric de-duplication. The de-duplication process compares the resident’s demographic and biometric information, collected during the process of enrolment, with the records in the UIDAI database to verify if the resident is already in the database or not. An individual needs to enrol for Aadhaar only once and after de-duplication only one Aadhaar shall be generated. In case, the resident enrols more than once, the subsequent enrolments will be rejected.
