From all bitwise operations only XOR is reversible. Look for XOR-cipher, the easiest way to encrypt your data. In your case you still have to know at least one number from both to restore the second one! There is no way that you can restore both.

You can use a bitwise xor to achieve this, it's known as a xor cipher.

OR is not reversible. XOR is reversible.
