Meanwhile, commenting on The Tribune's report on the leak of Aadhaar data, former US National Security Agency contractor and whistle blower Edward Snowden said it was a "natural tendency" for any government to seek the flawless records of private lives.
The paper said it bought access for as little as Rs 500 from someone on a WhatsApp social media group.
"The reported case appears to be instance of misuse of the grievance redressal search facility".
"Mere display of demographic information can not be misused without biometrics", it claimed in a statement.
An investigation into the Aadhaar security loophole by the Tribune has showed that details of the 12-digit unique identification number is easily accessible.
The Supreme Court is holding hearings to decide if a drive by the administration of prime minister Narendra Modi to link Aadhaar to private and public services infringes the privacy rights of individuals. A form provided by the UIDAI for this objective has to be downloaded, printed and duly filled, and sent via an India Post mail to the UIDAI along with self-attested copies of required documents, according to the Aadhaar card issuing authority.
UIDAI said even its grievance redressal search facility offers only limited access to the name and other details and "has no access to biometric details".
The UIDAI maintains complete log and traceability of the facility and any misuse can be traced and appropriate action taken.
In its point-by-point response to UIDAI's denial, the newspaper said UIDAI's admission that the search facility on its website had been "misused" did not change the fact that the theft had taken taken place.
UIDAI said since it maintains full log and traceability of the facility, legal action including FIR against the persons involved in the case, is being initiated. "The fact is that it has been misused to steal data - personal information such as name, date of birth, address, PIN, photo, phone number, e-mail - at will, for any Aadhaar number". However, the authority said that there had not been any breach of the biometric database.
