1. A method for creating a unique digital fingerprint for a physical artifact, the method comprising:
capturing, by a device, a current digital image of a region of interest containing the physical artifact;
transmitting, by the device, the current digital image to a server, the server generating data corresponding to a graphical indication of a segment by processing the current digital image to identify at least one high entropy area or low entropy area, wherein the graphical indication of a segment identifies the location of the identified at least one high entropy area or low entropy area;
receiving, by the device from the server, the data corresponding to the graphical indication of the segment; and
presenting, by the device, an instruction to capture a next digital image of only a segment of the region of interest captured in the current digital image, the instruction guiding a user to re-position the device closer to the physical artifact thereby to obtain a higher-resolution capture of the segment in the next digital image, the instruction comprising the graphical indication of the segment generated based on the current digital image.
