India’s Unique Identification (UID) project keeps getting hotter with each passing week. A day after Cisco and Yahoo grabbed headlines for wanting to be a part of the Nandan Nilekani-led multi-billion dollar project, now it’s internet giant Google which wants a piece of the UID pie.

Google, on Thursday, said it would be “happy to help” India in implementing the project, if they are approached. “We are not proactively approaching the government to be a part of it. It’s up to them to decide how we can help,” Google India MD Shailesh Rao said.

Even as the offers keep coming-in, UID chief and former Infosys co-founder Nilekani, who was in Bangalore for the platinum jubilee celebrations of the Indian Academy of Sciences, said it was going to be a huge challenge to register 1.03 billion Indians.
