1. A method for digital immunity comprising: identifying a call graph of an executable entity; mapping nodes of the call graph to a cipher table of obscured information, each node based on invariants in the executable entity, the cipher table maintaining associations between the invariants and the obscured information, wherein the obscured information defines a steganographic target; extracting, from the cipher table, ordered portions of the obscured information, the ordered portions having a sequence based on the ordering of the invariants; and detecting that the obscured information matches a predetermined ordering corresponding to a desired operation, wherein the step of detecting further comprises the steganographic target generating a result corresponding to a desired action.
