Hi,

The process for creating an encrypted folder is described here: https://help.ubuntu.com/community/EncryptedPrivateDirectory

It should contain all the information you need. If not, feel free to ask for any doubt you have.

I'd just set the owner to your username and usergroup then chmod it to 600

so for a user foo and a folder named bar

chown foo:foo ./bar; chmod 600 ./bar

Now only your usrname can access the data

Setting permissions is not a safe way to protect data against people. In fact, any person that can use `sudo` will be able to see any folder. Also any person with physical access to the machine may see the data, if not encrypted: for example, you can view files using a live CD or, in the worst case, putting the hard disk on an another computer.

This is why I think that encrypting the directory is the best way to restrict access to it.

Can you help with this problem?
