Printer Steganography
22nd April 2022
Before starting this research, I was unaware of the presence of yellow dots on printed paper. I find it remarkable that something so common on an everyday object could be this unknown to the public. Learning and becoming a master on a subject few people even know about feels fantastic. Even the majority of law enforcers have only heard rumors that it exists. The research itself was challenging because of the monotonous coloring and reviewing of the patterns. However, the moments when I found something useful were rewarding enough to continue.
