Despite massive efforts to guard sensitive data, hackers often manage to steal it anyway. It’s a problem that’s becoming especially acute, now that huge amounts of information are being concentrated on the servers of various cloud service providers. Most times we don’t even know where these machines are located; how can we possibly feel that our data is safe with them?
Here’s one way: Encrypt the data before it’s stored. That way, even if attackers manage to break into the cloud provider’s system and steal data, they’ll just get meaningless gibberish.
