That's according to research by accounting and consultancy firm Ernst & Young, which suggests that more than half of people — 55 per cent — say they're comfortable sharing personal information with central government organizations ... However, consumers are more wary about sharing their data with private companies. Just one-third told Ernst & Young that they're willing to share personal information with financial institutions, while one-quarter are happy to do so when it comes to their energy provider. Only one-fifth of those surveyed said they're comfortable sharing personal data with supermarkets. ... it was web firms that people were most claimed to be wary of sharing information with — fewer than one-in-10 said they were comfortable about sharing data with social networks, such as Facebook or web search engines like Google.'"
Meanwhile, a pair of researchers have assessed the NSA's data gathering scheme and found, unsurprisingly, that it's probably not very cost effective

"Conceivably, as some maintain, there still exist some exceptionally dim-witted terrorists or would-be terrorists who are oblivious to the fact that their communications are rather less than fully secure. But such supreme knuckle-heads are surely likely to make so many mistakes — like advertising on Facebook or searching there or in chatrooms for co-conspirators — that sophisticated and costly communications data banks are scarcely needed to track them down."
