Origin of term "Informational Hygiene"

Does anyone know where this term came from, and what the strict definition of it is? Roughly it means, care taken in the transmission of data/knowledge so that there is no corruption or loss of the data/knowledge.

I first stumbled across it while reading Neal Stephenson’s novel Snow Crash, in reference to the Torah and the care taken in making copies of it, but in context it has a clear secular meaning.* I did some googling to see if I could find earlier/different sources for the term, but turned up bupkis.

I’m working on a project and having an official source to attribute this phrase to would be most helpful.

*p. 230 of Snow Crash if anyone is curious.

That is such a contemporary sounding phrase that you might contact Neal Stephenson, since he may have coined it himself or very likely would know it’s origin.
