1. A system comprising:
a first module comprising first processing circuitry configured to:
generate a first series of secrets; and
combine a generated secret with a first data segment to create a first modified data segment;
a second module comprising second processing circuitry and operable remote from the first module, the second processing circuitry configured to:
generate a second series of replica secrets, the replica secrets being duplicates of the first series of secrets; and
compare data in at least a portion of an unverified data segment received by the second module with at least a portion of a replica secret to determine if the unverified data segment is the first modified data segment.
