chmod number that creates most secure/private directories

On one of the servers I use that I share with other people, I have a folder of which its contents I don't want to be shared with other people on the network.

For example, everyone can access everyone's home folder. I want to make this folder so that no one else can even cd to it or ls in it. I am not the administrator on the server, and I don't want the admin to have access either. Is this possible?

No.  Root access can see and do everything.

What about encrypt the file? I don't know it is useful, but you can try.

You can use "chmod -R go= <directory path>" to prevent other users from looking into the directory, but not root. Use encryption for that (e.g. EncFS, Truecrypt, GPG)

Of course, to be *really* secure, do "chmod 000". 
Root can still read it of course...
