PURPOSE: A random typed identification material irregularly dispersed in a 3D(Dimensional) shape, and a device and a method for 3D identification using the same are provided to facilitate manufacture, prevent duplication, and apply for diverse applications such as security certification, authenticity confirmation, and identification. CONSTITUTION: Identification particles(12) are irregularly dispersed in the random typed identification material(10) of the 3D shape. An identifying tool identifies a coordinate value of the identification particles dispersed in the random typed identification material from one or more direction on a rectangular coordinates system.
