In one of the possible questions in Captain Cryptic's Confounding Quiz it is revealed that when a duplicate is created, it is illegal to save the data of the original person for privacy reasons. In another, it is mentioned that duplicates are programmed to greet people with "welcome" in order to distinguish them from real people. This, however, is not true of the Alyssa Zaidelle Duplicate that Serah and Noel meet, suggesting that this feature was not programmed into the Duplicates created before Serah and Noel changed the timeline.
