Claim 18:
19. A system comprising:
a user interface device; and
one or more computers operable to interact with the user interface device and to
obtain a first set of information regarding a diamond material to be verified, the first set of information comprising hundreds of values for channels of a spectrum of electromagnetic radiation emitted by the diamond material in response to an irradiation of the diamond material by electromagnetic radiation having sufficient energy to convert a portion of the diamond material into a plasma, wherein the irradiation of the diamond material has been performed by a scanner that has been calibrated (i) for wavelength measurements using a light source with distinct spectral lines and (ii) for intensity measurements using a deuterium-tungsten light source, the hundreds of values representing physical characteristics of the diamond material to be verified;
obtain a second set of information regarding the physical diamond material to be verified;
send the first and second sets of information over a communication network to a verification computer system;
receive verification information from the verification computer system, the verification information comprising a digital signature by the verification computer system of at least information usable to identify the first set of information, the digital signature having been generated by encrypting the at least information usable to identify the first set of information using a private key portion of an asynchronous encryption key pair used by the verification computer system;
initiate addition of the information usable to identify the first set of information and the digital signature to a distributed digital ledger;
receive confirmation of the addition of the information usable to identify the first set of information and the digital signature to the distributed digital ledger; and
report that the diamond material has been verified responsive to receipt of the confirmation.
