I just ran across this in Bruce Schnier's October 15 CRYPTO-GRAM newsletter. NASA wanted to sus out whatever was hiding in a complex data set cataloging many types of failures in space batteries (NiCDs) produced by three different manufacturers.

The NASA paper.

They obviously farmed out the heavy lifting to some other agency since NASA could have had no native crypto talent in the late 60s.

It's interesting. They were successful at bringing the hidden meanings out of the data. It makes me wonder how many other complex data sets have been quietly analysed in this manner in the last 40 years.
 
You can be sure Homeland Security is analyzing everything they can get their grubby little hands on...
 
Hello Sub Umbra,

Perhaps it is time to dust off the punch cards and have a look at modern cell failures...

I believe separator failure ended up bing the most common failure, eventually.
