Assuming that I created a cloud-based website application that people literally all over the world could use, are there any countries in particular that do not like personal data being encrypted and stored within a database and used in this manner?
I'm not saying about storing unencrypted data, I mean about countries that do not like the idea of their people storing data online in an encrypted form.
(I ask this after the United Arab Emirates recently stopped RIM's Blackberry devices working because of such encryption...)
Here is a place to start. From what i can conclude, you should only have problems with countries that are somewhat totalitarian in nature.
EDIT: It is not a complete list, and probably will never be a complete list because countries who abuse civil rights tend to not advertise this fact...
