At the end of the 18th century when the French Revolution began to define the bases of a new conception of the State, one of the concepts that started to be developed was recognition of the individualization of the person.
This recognition resulted in the creation of documents proving that a citizen was duly registered in the national archives. However, it took two centuries for that document to end up having the format of the current Spanish DNI (National Identification Card).
At present, thanks to OCR technology (Optical Character Recognition), which seeks to emulate the human eye's ability to recognize objects, we take this one step further in order to electronically identify people. We’ll tell you about it in the following post.
