DESCRIPTION:

BRIEF SUMMARY
OBJECT OF INVENTION

This invention, as described in the presentation of this descriptive report, refers to a biometric security system and authentication of identity cards, visas and passports, as well as the face identity of the holder, whose purpose is to provide these identification documents with univocal elements of identification and validation which will allow both the holder and these identity documents to be authenticated as genuine or false, if they have been fraudulently reproduced or handled, changing or replacing the identity, personal characteristics or face image.
To obtain this end a security or validation system has been designed, printing certain colored lines on the identity document in the form of a grecque or filigrees which in a coded and univocal manner represent the topology of the actual card or identity document in its most sensitive parts, so that when any attempt is made at reproducing or forging these identity documents, this fraudulent reproduction or handling is clearly and irrefutably revealed.
The security validation which is object of the invention is based on a double application in this proposal. First of all points are taken at random on the identity card or document using a parameter algorithm. The choice of these points will depend on parameters such as, for example, the birthdate of the holder, with will thus individualize the choice of these points by means of a scanner which analyses the colour of each point or its tones of grays, where these values are numerically coded and in turn assigned an equivalence to a specific colour. With this numeric or colour code which is printed on the card in the form of a grecque or filigrees of colored lines, an univocal code of the card or identity document is formed.
In addition, the formation of a data base of master/pattern features is also object of the invention, which closely applies to the authentication of the individuals and their identity documents or cards, where, by comparing the zones of the face features, a synthetic image of the individual can be obtained by adding the basic features that are taken from the data base on master/pattern features, which in turn allows a numeric code to be made and a translation into its equivalent colour code, so that, from what has been explained above, this numerical code or the colour line grecque is printed on the card or identity document as validation, completed with the additional coloured lines that code the date of birth, christian name and surname with their first initials or in full.
The invention makes it possible to use and make the two validation modalities compatible in one and the same top security identity document or card, and also the face identity of the individuals who are the holders of these identity documents.
Closely related with the authentication of individuals and their identity documents or cards, a data base of master/pattern features is formed where by comparing the areas of the face features, a synthetic image of the individual can be obtained by adding the basic features that are taken from the master/pattern features data base, which in turn allows a numeric code and translation in its equivalent colour code, and, as mentioned above, this numeric code or the grecque of coloured lines is printed on the identity document or card as validation, and this is completed with the additional coloured lines which code the date of birth, christian name and surnames with their first initials or in full.
To procure maximum security in the production of these documents, the invention foresees that the document in question embody some special covers on which all the safety validations relating to pigments will be printed directly, and also all the colour codes or filigrees, on the extrusion on their inner polyolefin or polypropylene or low density polyethylene face and in this way, likewise all the holder's personal data, face image that is obtained from the scanning and digitalization of the photo which the holder submits for each identity document, along with the
