A cottage industry is growing up around virtual padlocks that consumers can place on cloud services so that the vendors themselves can't get to the information -- even if the government requests access.
And in recent years there have been a lot of those government requests for access from storage-as-a-service providers.
For example, Google regularly receives requests from governments and courts around the world to hand over user data. Last year, it received 21,389 government requests for information affecting 33,634 user accounts. Sixty-six percent of the time, Google said it provided at least some data in response.
