Paul, Thanks for the response. I would like to rephrase my question. I have a number and would like to fudge it such that
It is unique and has a one to one mapping with the old number and it should be random and not predictable. Any possible solutions here. Of course the fudged number could / can lie in a different number range slightly. Say a four digit number garbled could give me a unique random 6 six digit random number.
