Relations among pattern studies?

[Torsten]

About Patrick's presentation, it's making me wonder the same thing that usually crosses my mind whenever we enter the realm of steganography, nulls, verbose ciphers etc. In other words, whenever the true information has to be filtered out from the surrounding non-information. And that is the following:

When exploring steganography, Jürgen Hermes' paper about the Polygraphia III by Johannes Trithemius is worth reading. Trithemius (1462–1516) devised a cipher where words are used to encode plaintext letters [see You are not allowed to view links.

For instance it could be necessary to count the number of curved glyphs between two gallows, or all instances of a glyph like EVA-[i] within a line. However such methods would require an enormous effort to encode a relatively short message [see You are not allowed to view links. Register or Login to view.].
