A secret is an item of information, and as such falls under the wing of information science, one of whose branches is mining, the extraction of information (secrets) from tons of data.
The masters of information have forgotten about poetry, where words may have a meaning quite different from what the lexicon says, where the metaphoric spark is always one jump ahead of the decoding function, where another, unforeseen reading is always possible. – Diary of a bad year, J.M. Coetzee
