|Desktop Training - Ubuntu|
One of the features in Ubuntu 9.04 Jackalope is the ability to create an encrypted directory for content you do not want others to access. You can create n encrypted directory for your user at install or you can add encryption after you have installed.
Oh, by the way, did you know that anyone can read your files that are in your home directory? Here is an example of sue logged in and able to open files in mike's home directory. However, note that they are opened read-only so they cannot be changed. Still, who is looking at your stuff?
So it makes sense to encrypt your files if you do not want others to access them.
If you have the permissions you can right click on a file and encrypt it. You will need to generate a key so that you can do that but it is easy to do so. Right click on the file you want to encrypt and you will see "Encrypt" in the menu of Nautilus.
You will have a choice of keys to create, here a PGP Key is created that can be used for mail or for files.
That is all there is to it unless you want to guarantee privacy using permissions in the file system.
Privacy Through Permissions
Another way to solve privacy issues is to change the permissions on what people can see in your home directory. As the owner/user of the directory you can do this with a command from the command line. Here is an example of the command to use if your login was tom:
chmod -R 750 /home/tom/
Now that will change permissions on existing file but not new files created so you will want to change the umask on the system, or the permissions of all files that are created.
Changing Permissions with the umask
