DEDA: Extracting, Decoding, and Anonymizing Tracking Dots from Printed Documents

DEDA is an open-source toolkit for extracting, decoding, and anonymizing tracking dots embedded in printed documents. Color laser printers often leave tiny tracking dots containing information like the printer's serial number. DEDA can read and decode this information, and also anonymize documents to prevent tracking. It offers a GUI and command-line tools for various operations, including extracting dots, comparing printers, creating custom dots, and anonymizing scans and documents. Installation requires Python 3 and several dependencies; troubleshooting tips for common installation errors are provided.
