“…The identification of inconsistencies and consistencies generally involves internal trace consistency (type C) and consistency with external "events" (type D). [11] Type C inconsistencies in messages include things like (1) messages with identical identification numbers or similar tags that have different sourcing or content, (2) identical headers with different bodies, (3) multiple messages with identical "unique" identifiers, (4) supposedly identical sources that travel in excess of realistic travel rates for the transport technology, (5) overly or underly consistent delay times in the apparent processing of messages, (6) ordering errors and differences in header sequences, (7) commonalities in messages with different identified sources and travel paths, (8) self-indicating integrity flaws like digital signature mismatches, (9) large numbers of messages with highly correlated content and headers that are supposed to be independent, and (10) travel patterns inconsistent with normal processing.…”
