Internet of Tattoos? NIST Workshop Plumbs Body Art Algorithms

The article summarizes a NIST workshop and tattoo recognition technology challenge that brought together academia, industry, and government to develop automated image-based tattoo matching. It outlines participating organizations (including MITRE, Purdue, Fraunhofer, MorphoTrak), methods like SIFT and systems such as Purdue's GARI, reports that algorithms performed well on detecting same tattoos over time but struggled with matching visually similar tattoos across different people or sketches, and highlights privacy concerns about the potential for pervasive surveillance using tattoo recognition combined with cameras and drones.
