Information confirmation system

A method for confirming information using multiple information gathering subsystems is provided. In one embodiment, the method attempts to gather primary information using a first information gathering subsystem. The method also attempts to gather secondary information using a second information gathering subsystem. Thereafter, the method compares the primary information when gathered by the first information gathering subsystem with the secondary information when gathered by the secondary information gathering subsystem. In various embodiments, information gathered from one information gathering subsystem can be used to derive information not retrieved (due to a failed gathering attempt) from the other information gathering subsystem. In still other embodiments, a third information gathering subsystem can be used to gather tertiary information. The tertiary information can be used when needed to confirm or derive primary or secondary information. In yet other embodiments, a computer-readable medium, an apparatus, a processor, and system are also provided which perform similar features recited by the above method.
