How your print is made
Seven steps, from two inputs. The same two always give the same print, and no two applicants share one.
Details
- Seed.
keccak256("applicant:" + X id + ":" + wallet): 32 bytes in a namespace of their own, never an archive print's seed (those come from the person's Q-number). - Settled. Pattern, slant, cores and deltas, warp and outline are compared with all 40,025 archive prints; too close, and the seed is re-hashed (
keccak256(seed ‖ "reseed:n")) until the print is clear. Once, when you apply. - Pattern. Byte 10 of the seed: Arch, Loop, Whorl or Double loop, about as often as real fingers have them. This card: Whorl.
- Ridge spacing. From the first mark's year (2010 or before the widest, 2022 on the finest): 7.35 px. Archive prints use other spacings, so no applicant print is ever traced like one.
- Outline. Which fingertip, from how the wallet has been used: Crown, the first mark is on chain, 2017 or before (the right thumb). Light, and never a judgement.
- Ridges. A field of cores and deltas placed by the pattern, bent by two warp waves, traced as evenly spaced streamlines. The tilt comes from bytes 6–8 of the seed, the ink's grain from byte 11.
- The card. The print, whole and in light ink on the night paper, beside the handle, the case number, the first mark and the day's life. The wallet is never on it.
