The latest US snooping controversy has highlighted more than just online privacy issues. It has shown up a massive and extensively-backed security industry. So what is your data worth to governments and the likes of Facebook and Google? And how safe is your privacy?
PRISM is a top-secret electronic surveillance programme run by America's National Security Agency - at least it was top-secret until a former NSA worker blew the lid off it.
Nations spend billions spying on their own citizens and people overseas - whether that is hacking, intercepting phone calls or just requests from governments to private companies.
In the US, the Central Intelligence Agency (CIA) and other non-military spy agencies will get $48bn next year. The UK is spending around $3.6bn on its spy agencies. And China's spending on "internal security" was $111bn last year.
Security services, and the private contractors they use, are trawling for data which would, in theory, make us safer. But the idea that the likes of Google, Facebook, Microsoft and Apple gave backdoor access to the NSA to snoop on users' data, has concerned many people.
They all deny it, but still, it begs the question of what your data is really worth - given that most people simply hand over their photos, personal information, and documents to such websites without giving it a second thought.
The data industry in the US alone is worth $300bn a year and it employs some three million people. That is coupled with the online sales industry, which generates $10tn per year.
All of this is managed by the more than 2,000 so-called 'data broker companies'. Acxiom Corp is the biggest - with a profit of $77mn in 2011, coming from the largest commercial consumer database with 500 million active users worldwide.
