Google has reported a "steady increase" in government requests to hand over data from internet users in the second half of 2012.
The web giant's semiannual "transparency report" showed the most requests came from the United States, with 8,438 requests for information about 14,868 users.
India was second with 2,431 requests for data about 4,106 users, followed by France, where Google received 1,693 requests for information about 2,063 users. Germany, Britain and Brazil rounded out the top six, Google said on Wednesday.
"The steady increase in government requests for our users' data continued in the second half of 2012, as usage of our services continued to grow," said Richard Salgado, Google's head of law enforcement and information security.
"User data requests of all kinds have increased by more than 70 per cent since 2009," he said in a blog posting.
"In total, we received 21,389 requests for information about 33,634 users from July through December 2012."
Google said it supplied at least some of the requested data in 68 per cent of cases, down from 76 per cent in late 2010.
In releasing details of requests in the United States, Google said 68 per cent of the requests it received from government entities were through subpoenas, which "are the easiest to get because they typically don't involve judges," according to Salgado.
Another 22 per cent were through search warrants, mostly issued by judges when there is "probable cause" related to a crime.
Google provided at least some data in 90 per cent of the requests in the United States in late 2012, compared with 94 per cent two years earlier.
