The ball will be used in all of the tournament’s 64 matches, and will feed information back to a data nerve center, which officials can use to track statistics and monitor game play.But in this tournament, officials will try to minimize the controversy by using video assistant referees, which use algorithms and data points to help on-field referees make accurate calls, FIFA officials said.In Lusail Stadium, which holds more than 80,000 people and where the final match will be held, facial recognition technology will be used to track fans, according to Al Jazeera, which has generated concerns over privacy.The command-and-control team, news reports said, will be able to forecast crowd patterns using algorithms that rely on several data points, including ticket sales, and places where people enter.They relied on a data set from GitHub, a website for sharing and collaborating on computer code, which tracked the results of every international soccer match since 1872, they said."
