"Data has become the new oil. Just like oil was the basis for transformation of the 20th century, data is the basis for 21st century.
"But it is very important that if data is the new oil, then data is democratised (and) that data is available to everybody to use," Nilekani said in his address at the 54th convocation of Indian Institute of Technology, Madras (IIT-M).
"In India, we have a chance to do that, thanks to the technology we have and what that means is that a consumer can get his own data to get a better loan, better health care, education. A business can use data to get better credit or better business.
"So therefore, if data is the new oil, and if we can restructure data to benefit every individual and every business, then we can lead to enormous amount of activity and economic growth. So we have a chance to build a completely new paradigm on data which no other country can do," he said.

Over the last eight years, India has built a very sophisticated stack of software tools which a billion people can access, he said.
"It is based on everybody having a unique ID, the Aadhaar number. You can use that for doing authentication wherever you are (using) your phone, you can use that for doing a KYC (Know Your Customer) which allows you to open a bank account or get a SIM card. It allows you to electronically sign and store documents and it allows to access your own data," he said.
These were really "large national scale systems" that have been built in India and will allow creating a new class of solutions, that would be dramatically cheaper than anything being done today.
India was also building systems which were creating national level platforms for many things and the GST Network was a good example of this, he said.
"Because, for the first time in India, eight million businesses will be on one platform, because earlier those who paid excise duty or VAT, they will all be on one platform. So all the taxpayers in India, the business taxpayers who pay indirect tax, they have to file invoice line item level returns into the GST network.
"So if you have 8 million businesses in India who do 120 line items a month, we are talking about a minimum of one billion line items that are going to be recorded every month in the GST system.
This data will allow getting a real time sense of the economy, because there will be information on a daily or weekly basis whether the economy was growing or not and which regions were doing well and so on, he said.
Digital transactions can also be used to avail credit.
"Suddenly eight million businesses will become eligible for credit as companies will be able to demonstrate their performance, and there are many other such systems coming up," he said.
