The main aim behind this paper is to develop new preprocessing discrimination prevention methodology which consist of different types of data transformation methods. With the help of that direct discrimination, indirect discrimination or both of them at the same time get prevented. For making the final decision there are two steps in which first step include identification of categories and makes groups of individuals whatever it may be, directly indirectly discriminated for making decision.
