While the release of another Ubuntu is only a few days away, there are some interesting security features in place. One being the encrypted directory.
Encrypted “Private” Directory - While many OSs now offer whole hard-drive encryption, most people probably only have a small set of their files that they want to encrypt. Instead of offering an encrypt everything or nothing option, there will be a folder in each user’s home folder called “Private” that will be encrypted. This would be useful to store confidential documents and that sort of thing without slowing down access to less-confidential stuff, like your music.
