Printer Serial Number Randomization

Printer Serial Number Randomization

Whisk Experiment

To remove serial number from printout 

Additive printer 

Conventional paper printer 

Firmware alteration

Serial number randomization

printer "fingerprint" would be useless with this setup

-remove tracking data from printed structure-

-currently a 3D printed kinetic weapon contains information in the printing to locate the manufacturer

rough firmware example:

import secrets

import string

# Generates a 16-digit string using only numbers

random_number = ''.join(secrets.choice(string.digits) for _ in range(16))

print(random_number)

Printer tracking dots https://en.wikipedia.org/wiki/Printer_tracking_dots

found in printing press, typewriter, 3D printers, etc.
