29. The system of claim 1 , wherein said source identity association module configured to associate the source identity data with the particular item, the source identity association module including at least a source identity inclusion module configured to include into the electronic message one or more identities of the one or more sensors, the one or more sensors having been used to derive, at least in part, the inference data acquired by the inference data acquisition module comprises: a source identity inclusion module configured to include into the electronic message the source identity data acquired by the source identity acquisition module, the acquired source identity data including at least one or more identities of the one or more sensors.
29. The system of claim 1 , wherein said source identity association module configured to associate the source identity data with the particular item, the source identity association module including at least a source identity inclusion module configured to include into the electronic message one or more identities of the one or more sensors, the one or more sensors having been used to derive, at least in part, the inference data acquired by the inference data acquisition module comprises: a source identity inclusion module configured to include into the electronic message the source identity data acquired by the source identity acquisition module, the acquired source identity data including at least one or more identities of the one or more sensors. 34. The system of claim 29 , wherein said source identity inclusion module configured to include into the electronic message the source identity data acquired by the source identity acquisition module, the acquired source identity data including at least one or more identities of the one or more sensors comprises: a source identity inclusion module configured to include into, and as one or more parts of, the electronic message an identity for at least a functional near infrared (fNIR) device used to derive the inference data acquired by the inference data acquisition module.
