Base Claim:
1. A method, comprising: pretreating a textual message that includes a plurality of semantic sentences suitable for use in generating a sequence of binary bits, with each bit of the sequence of binary bits corresponding to a respective one of the semantic sentences; determining that a number of the plurality of semantic sentences in the textual message is of a sufficient number to carry a code, wherein the code includes one or more bits; selecting a subset of the plurality of semantic sentences to carry the code; embedding the code in the selected subset of the plurality of semantic sentences to generate a pattern of binary bits, wherein the pattern of binary bits corresponding to the selected subset of the plurality of semantic sentences matches a pattern of the one or more bits of the code; and tagging the selected subset of the plurality of semantic sentences.

Claim 6:
6. The method of claim 1 , wherein the tagging the subset of the plurality of semantic sentences comprises tagging the selected subset of the plurality of semantic sentences such that the binary bit corresponding to each of the tagged semantic sentences indicates a respective one of the bits of the code.
