Yes, even I am dishonest. Not in many ways, but in some. Forty-one, I think it is.

Seems that Alice and Bob could avoid the data breach by using their own encryption software and keys instead of the ones supplied by Provider. Or am I missing something?

I only use the cloud for stuff I want to share with everyone as that's who can get to it. Mainly pix and videos of the grandkids...

My understanding is that encryption on your own machine and uploading it to the Cloud is not 'safe' if you send it to someone else, or allow them access to the stored data. If you don't share it may be safer.

Think of using the "Cloud" as a giant warehouse (or several since there are many "Cloud" storage companies). The security guards (the Provider and encryptment) guard the place. You want Bob to be able to see what you stored, so you tell the guards to allow Bob to see that. Somebody with the guards get mad at their company (or takes a big bribe) and allow anyone to see the files you saved. OR a government official arrives and has papers to look around the warehouse. How safe is your file?

Say your file has hard evidence that the Illuminati has caused this World wide financial crisis purposefully, and identifies everyone one them. The government official could 1- remove the file and destroy it, 2- alter the file and name others not involved to take the blame, OR 3- use this to have you arrested.

How safe is your file? The "Cloud" is merely computer servers that save your file. If something happens to the servers, your file is gone.

A rather pessimistic view. Some cloud services have multiple copies on different servers. Individual users with poor security practices are every much at risk with files stored on their computers.

Wuala encrypts files and does not have your password. More security than most users have enabled.

Many use Internet banking. If one does, is that any more secure than cloud storage? To be perfectly secure use pencil and paper for everything, do not use ATM's and throw your computer into the garbage, after destroying the hard drive. And then hope your brother-in-law does not steel your papers.
