Arizona has authorized the use of digital license plates for motor vehicles. Proponents say plates could revolutionize the driving experience and makes things like vehicle registration renewal more convenient. But others, including Aviral Shrivastava, a Fulton Schools associate professor of computer science, say such plates, which work off of cell phone networks, pose potential problems with data security and privacy for drivers. Hacking of the embedded systems technology used by the plates could lead to theft of information about automobiles and drivers, Shrivastava says.
