Hacker Lexicon: What Is Homomorphic Encryption?  03 November 2014 
Source: Wired - Posted by Dave Wreski   
The problem with encrypting data is that sooner or later, you have to decrypt it. Keep your cloud files cryptographically scrambled using a secret key that only you possess, and it’s likely no hacker will have the codebreaking resources necessary to crack them.
