Claim 5:
6. The method of claim 2, wherein the computer is part of an analysis system, wherein a number of the channels of the spectrum used to verify an identity or provenance of the diamond material is application-specific, wherein the digital signature is a first digital signature, and wherein:
obtaining the first set of information comprises irradiating the diamond material, receiving the spectrum of electromagnetic radiation responsive to the irradiating, and generating the hundreds of values from the received spectrum of electromagnetic radiation;
obtaining the second set of information comprises retrieving from the distributed digital ledger (a) previously produced hundreds of values for channels of the spectrum of electromagnetic radiation emitted by the diamond material in response to a previous irradiation of the diamond material and (b) a second digital signature of at least the previously produced hundreds of values, and verifying the second digital signature using a public key portion of the asynchronous encryption key pair used by the verification computer system; and
sending the first and second sets of information comprises sending the generated hundreds of values and the previously produced hundreds of values to the verification computer system.
