available options to create dummy ID??

jacobM — Fri, 20 Dec 2019 13:21:55 GMT

I'm wondering what are some common approach for creating dummy ID based on known numerical ID? some of my expectations include:

dummy ID should be 1-1 mapped to real ID and no duplicate

should be reversible, meaning that knowing the dummy ID I should be able to get the real ID through some program

include some form of randomization

Can any please help provide some potential approaches I could use? thank you

here is a simple way to create a linkage to the records. But you have to keep the have dataset someplace safe that others who should not have access to it can not reach it.

data have(keep=myid name);
 set sashelp.baseball;
 MyID = _n_*2.5/3.67;
run;

apply some type of sort order would also assist in mixing things up.
