Abstract
A system and method for encapsulating commercially significant attributes of a hydrocarbon product into a single digital signature are presented. The digital signature may be generated from a physical product sample using optical techniques such as NIR spectroscopy. Digital signatures may be expressed in the form of composition, principle components derived from the spectra, or other properties derived from the original spectra which characterize, and help visualize, the variation present within the signals. Other physical property measurements and contaminant measurements may also be included in the digital signature and may be derived from the same measurement device or separate measurement devices whose output is integrated into a single digital signature. Embodiments of the invention may be used to confirm the identity of a hydrocarbon product, or to verify the composition of a hydrocarbon product.
