- Document Colour Tracking Dots (yellow dots) encode printer and printout information in almost every commercial color laser printer.
- The software allows for reading, decoding, and anonymizing tracking dots to prevent arbitrary tracking.
- Installation requires Python 3 and Deda, with optional Wand for anonymizing images with white areas.
- Commands like `deda_parse_print`, `deda_compare_prints`, and `deda_extract_yd` help analyze tracking dots.
- Anonymization involves creating a mask with `deda_anonmask_create` and applying it with `deda_anonmask_apply`.
- Solutions for common issues include adjusting scan settings, installing dependencies, or modifying ImageMagick policies.
