Abstract:
1. A method comprising: Using at least one processor to perform steps of: generating a digital signature for a first mole, based at least in part on a digital image of first, second, and third moles; accessing baseline data that contains baseline signatures for previously imaged moles; and determining whether the first mole matches a previously imaged mole, based at least in part on the digital signature for the first mole and at least one of the baseline signatures in the baseline data; wherein the operation of generating a digital signature for a first mole comprises at least one operation from the group consisting of: recording an angle entry for the digital signature, the angle entry representing an angle between (a) a first line to connect the first mole with the second mole in the digital image and (b) a second line to connect the first mole with the third mole in the digital image; and recording a distance entry for the digital signature, the distance entry corresponding to a distance between the first mole and the second mole.
