DEDA is a Python toolkit that extracts and decodes the tiny yellow tracking dots that colour laser printers embed in printouts, which encode info like the printer's serial number. It includes a GUI and CLI tools to parse scans, compare prints, analyse unknown dot patterns, and generate anonymisation masks to print documents without tracking dots.

Why now: Renewed attention on Hacker News around the privacy implications of printer tracking dots and this toolkit for decoding and defeating them

Who it is for: Privacy researchers, forensic analysts, and anyone concerned about printers revealing their identity on printed documents
