That in itself tells me enough about the efficacy of the system. Security through obscurity is only a hand wave of security. Making the trade off of all the security architecture put in place over the past decades for something that needs to be hidden to remain secure is a really poor value statement.

I understand why they want this in place, it does raise the level of effort on cheating but there are other ways this can be accomplished without compromising a user's security.
