Re: how to create a transformation subroutine only for one column of table for security purpose ?
Hi Peter ,
Thanks for reply .
Date 22/2/2017 refers to date of swipe of credit card for user . And actually it drives every thing of algorithm .
If the date of use falls on first day of week i.e Monday then there is a set of logic , if its on 2nd day of week i.e Tuesday then there is different logic . It is just that i have highlighted logic for 7th day because 22 jan 2017 was sunday .
Other 5 algorithm i will be taking care , after going through solution for above two days
