spell out the numbers backwards in arameic.
or come up with a simple arithmetic code to it that only you know
(first digit add 1, second digit add 5, third digit add , fourth digit add 5, etc. or any similar pattern...very hard for anyone to know what system you used, and if you don't say in the file what the number is for, you're even better off)
