A new vehicle license plates system has been deployed in some countries of South America. The plates enumeration is based on a common pattern shared by Mercosul (Southern Common Market) member countries, under a formal agreement. However, the proposal signed by these countries follows the same old recipe of distributing a range of plates according to regions and identifying cities/states explicitly in the plate. We propose a new way of thinking about vehicle license plates, considering the citizen privacy and the effectiveness of OCR (Optical Character Recognition) systems. Every newly generated plate characters’ sequence is evaluated against all other existing sequences, in order to avoid confusing characters in a given position of the sequence, which improves the automatic identification of plates. By using plate’s images and data collected by the Brazilian Federal Highway Police systems, we could identify most confusing characters.
