Claim 23:
24. The system of claim 20, wherein the one or more computers are 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 the one or more computers are operable to:
obtain the first set of information by being operable to irradiate the diamond material, receive the spectrum of electromagnetic radiation responsive to the irradiation, and generate the hundreds of values from the received spectrum of electromagnetic radiation;
obtain the second set of information by being operable to retrieve 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 verify the second digital signature using a public key portion of the asynchronous encryption key pair used by the verification computer system; and
send the first and second sets of information by being operable to send the generated hundreds of values and the previously produced hundreds of values to the verification computer system.
