I have multiples databases in different servers, so is necessary install the scramble database in every database server to use the transformation maps, in my company this generate cost for administration of the scramble database.
So... is possible use Fast Data Masker for In-Flight Masking(How?) or used a centraliced scramble database between diferenst servers and database.
FDM performs in-place masking - it does not support in-flight masking, this is performed by the Subset tool.
However, you can achieve your goal by using a centralized Scramble database:
I hope this helps answer your question.
