In 2004 an article entitled “Government Uses Color Laser Printer Technology to Track Documents” appeared in the PCWorld magazine. The paper wrote that the color printer inserts the coded pattern in the printed document. There is a all in one printer serial number, date, and time of the document that forms the printed document’s coded design. There are dots less than 1 mm in diameter in the pattern, and you cannot see them with the naked eye.
The debate over computers tracking humans resurfaced when The Intercept published a classified report on June 5, three hidden points. After the information was leaked to the public domain, the FBI arrested someone for leaking classified documents to the public. He is a Reality Leigh Winner who was only 25 years old when he was arrested.
He was charged with a crime for stealing classified documents from government buildings and sending them to The Intercept, a US online mass media. The Intercept then published the intelligence document on Monday, June 5, 2016. The news describes in detail Russia’s efforts to hack the US voting system, a week before the 2016 presidential election begins. Although the document does not mention Russia’s attempt to change the election result, the hacking hacked into several voting system elements.
In a letter of accusation issued by the US Department of Justice, Winner admitted to photocopying the classified document and sending it to The Intercept. FBI officers found evidence that Winner had “The Intercept email address.” This Winner is one of six government officials who read the secret report.
Based on the capture of Reality Leigh Winner, the researchers finally investigated further about the points in the document. They concluded that the dot came from the printer, model number 54, serial number 29535218, produced at 6:20 am, on May 9, 2017. Leigh Winner had likely anticipated a lot to cover his tracks, and he probably printed the document more than six times.
Peter Crean, a senior researcher at the Xerox office, stated that the printer has security features and the code contained in the document only ensures the originality of the data. With the hope that people will use Xerox printers safely, not for counterfeiting money.
But people don’t believe this feature already, especially since America is a country where people uphold the right to privatization. Meanwhile, the Electronic Frontier Foundation (EFF) addresses the issue in a blog post, highlighting possible marketing technology exploits. According to him, every individual or group activity that uses the printer for political, legal, or medical conditions can be detected by the government without any legal process.
This assumption is reinforced by the finding of dots representing binary codes. They also claim that nearly every printer company known in various parts of the world has signed an agreement with the government so that any printed paper can be forensically traced. Each printer company started with a different method, a complex code like Canon that creates a spiral pattern, and only Canon’s researchers can solve it.
