Peter Wayner is an American writer known for his books on technology and his writing in mainstream publications including The New York Times, InfoWorld, and Wired magazine. His work on mimic functions, a camouflaging technique for encoding data so it takes on the statistical characteristics of other information, is an example of steganography, and was the basis of his 2009 book, Disappearing Cryptography. In 2018, he received attention for writing an article about the New York City transit system, advocating for replacing large subway trains with competing fleets of smaller, thinner and more nimble autonomous cars, scooters, hoverboards and pods. The article received widespread criticism.
