The fundamental difference is that embedded messages have a complete semantic quality, rather than mere imagery, and the mind of the target tends to key off of particular dominant patterns. The remaining information, carefully structured, speaks directly to the subconscious with a subtle, indirect, command. The effect is to produce a pattern of thinking that the attacker has predetermined but is buried within the message and not overtly stated. Structuring a human "buffer overflow" requires precise attention to detail and the use of information in a manner that distracts the conscious mind from the message the subconscious is receiving.
