The government on Wednesday said instances of violation of standard processes and guidelines for enrolment under Aadhaar project by agencies have been reported.

"Some cases of process non-compliance and fraudulent enrolment have been reported against some enrolment agencies in some places," planning minister Ashwani Kumar said in a written reply to the lok sabha.

"These enrolments were done in violation of standard processes and guidelines prescribed by the Unique Identification Authority of India (UIDAI) for Aadhaar enrolments," he added.

Under the Aadhaar project, UIDAI has been mandated to enroll residents in the country to generate a unique identification number for every individual and issue an Aaddhar letter as proof of identity.

In Anantpur district of Andhra Pradesh, two enrolments with fictitious names were detected, Kumar said, adding the operators involved in fake enrolments were black listed and removed from the UIDAI system.

A request was made to the state government to file an FIR against operator/supervisors and management of the concerned enrolment agencies, the minister said.

In another such instance in Hyderabad district in Andhra Pradesh, enrolment using photo of a photo by an operator was detected by the quality assurance team of UIDAI, the minister said.

In this case, the enrolment were done by misusing the provision of "Biometrics Exceptions" enrolments (where a resident with missing fingers or missing iris is enrolled following a special procedure).

The state registrar has lodged an FIR against the concerned operator and the UIDAI has issued a show cause notice to the concerned enrolment agency and suspended their operations, the minister said.

One such case was also reported in Karnataka "where fake certificates of proof of address and proof of identity were issued by some government doctors in the name of high profile dignitaries including the chairman of UIDAI chairman and relatives of the state chief minister", Kumar said.

A police complaint was filed against the doctors involved in issuing fake certificates and the accused persons were arrested, Kumar added.

UIDAI has has enrolled over 20 crore residents so far and in addition would collect biometrics data from 40 crore more residents.

It will also use biometrics collected by the National Population Register programme for generating the unique number for rest of the population of the country.
