Blockchain ledgers of material spectral signatures for supply chain integrity management

A system comprising:

• a memory that stores computer executable components;
• and
• a processor that executes computer executable components stored in the memory, wherein the computer executable components comprise:
• a validation component that:
• determines a difference between an encrypted first spectral signature data associated with a material and an encrypted second spectral signature data associated with the material;
• and
• predicts, based on the difference, a degradation of quality of a characteristic of the material that occurred during a transit of the material between a first spectral scanning device that generated the encrypted first spectral signature data and the second spectral scanning device that generated the encrypted second spectral signature data;
• and
• generates a block of information corresponding to the material in a blockchain indicating that a transaction of the material is settled as validated, wherein the set of information comprises the prediction of the degradation of the quality of the characteristic of the material that occurred during the transit of the material between the first spectral scanning device and the second spectral scanning device.

A computer program product for monitoring integrity of a supply chain, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• determine a difference between an encrypted first spectral signature data associated with a material and an encrypted second spectral signature data associated with the material;
• and
• predict, based on the difference, a degradation of quality of a characteristic of the material that occurred during a transit of the material between a first spectral scanning device that generated the encrypted first spectral signature data and the second spectral scanning device that generated the encrypted second spectral signature data based on the difference;
• and
• generate a block of information corresponding to the material in a blockchain indicating that a transaction of the material is settled as validated, wherein the set of information comprises the prediction of the degradation of the quality of the characteristic of the material that occurred during the transit of the material between the first spectral scanning device and the second spectral scanning device.
