I really have to take the anti-noise side here. I get why it's a hard problem, and I get why the Census Bureau thought this was a neat solution. But I'm imagining an accountant stepping through a similar chain of logic:

* I want to accurately report the finances of our company to the best of my ability.

* But that report would allow people to reconstruct private data about the terms of our contracts with various counterparties. I'd really like to avoid that, there's no rule that says we're supposed to release that data. In fact some of those contracts probably came with nondisclosure agreements!

* So here's what I'm going to do. I'm going to calculate our results to the best of my ability, and then I'm going to add random values to them and report only the randomized ones. Any reconstruction people try to do will be wrong because of the randomness.

* If the SEC says "no, you need to report your actual numbers", I will explain to them that there's no such thing as an actual number because all data is noisy.

I can't get behind it.
