I may then switch to USB drive instead of phone after all ... btw shorena , when I said my own encryption I meant the seed and not the paper wallet which I guess it should be harder if the cracker don't know what algorithm I'am using ?
also could someone tell me how I'am supposed to make USB drive with encryption and what should I put ? simple .txt that includes my seed?
As long as you use a known and good algorithm it does not matter whether you write its name next to it or not.

Well yes you put the .txt file in the USB drice and then encrypt it (the whole USB).
Most people use Truecrypt or Bitlocker but be careful once you forget the password you can't decrypt it.
Here is a short tutorial about Truecrypt
