Abstract
This invention involves a reading process for three-dimensional means of identification () that are unique and non-reproducible (), containing a mixture of at least two materials (and) that are distinguishable from one another (and), remarkable in that it consists of one part to recognize the internal heterogeneous structure of the means of identification () in two dimensions, and another part to verify and prove its third dimension to render falsification impossible. This characteristic reduces the amount of storage memory as well as the length of time necessary to perform the operations of reading, acquisition, and comparison usually conducted in such processes. The invention also involves a device that implements said process as well as a means of identification adapted to said process.
