"If a document is found to be forged you cannot deny it," added Sharma.

"From a citizen's perspective, it reduces the hassle of carrying physical documents. Suppose I have a digital locker and there is an agency which has issued a certificate in my name. There is a provision to push that certificate into the digital locker of the individual."

Giving an example, the top official said: "If a Class XII certificate is issued to a person with a Digital Locker it will have a link. This link can be shared. So wherever this certificate is submitted, it can be verified. One knows it is genuine. For the government, it is a great advantage. Since Aadhaar is unambiguous, the first stage of a person's authentication is already done."

This kind of infrastructure was unique to India and the government wanted to leverage that, said Sharma, adding that the potential could be gauged by the fact that more than 850 million unique identification numbers (Aadhaar) had thus far been issued to people.

So far, the 830,075 people who have signed up for the service have uploaded 430,324 documents. Maharashtra has the highest subscribers with Maharashtra 88,091 accounts, Uttar Pradesh is next with 79,499, followed by West Bengal with 74,453.

"Even the American social security number does not have a biometric database," he said. "Using the biometric authentication process, one can also link a mobile number to his/her identity. So my mobile number effectively becomes my digital identity."

Sharma said to cater to the large unlettered population of India, the government has also put an assisted mechanism in place to help open Digital Lockers. "One common service centre in each Panchayat of the country will be offering all kinds of digital services."

He explained that through these centres, one can do banking, get birth certificates and ration cards. "We have got 100,000 common service centres in the country which can basically provide assistance," said Sharma.

"This is the social inclusion aspect of a Digital Locker."
