1. A non-nominative, resilient biometric authentication system based, on the venous network comprising an infrared light source for illuminating a body part of a user, and a detection device, the system comprising:
a sensor for non-contact capturing a venous network of said body part, that obtained the biometric information;
an extraction unit of biometric characteristics;
a conversion unit of the biometric characteristics, the detection device (1) having a unique identifier, wherein the extraction unit of the biometric characteristics extracts a quantity of characteristics from the biometric information obtained by the sensor;
a means for extracting an image obtained from a first area of said body part, normalization of said image according to a predefined standard and processing said normalized image, segmentation of said normalized image and extraction of a tree structure and then search for a longest segment, mathematical characterization of nodes of said segment, matrix characterization of said nodes followed by initial encoding and application of an algorithm of the sequence matrix and matrix encoding of the sequence in order to generate a vascular fingerprint;
wherein the conversion unit of biometric characteristics converts said vascular fingerprint, via an encoding algorithm and combining the device identifier with the extracted characteristics, into a variable numerical identifier, so that said variable numerical identifier is not joined to said user's vascular fingerprint and is generated without any nominative identification information of said user and is specific to said data detection device;
wherein, the system further comprising a first server and a second server;
wherein the first server receives the variable numerical identifier generated by the detection device, said first server comprising a data generation unit, for generating the data by using a place, a date and anonymous information or a logistic parameter such as a coding of the reader and/or coding of a version and a number of the used algorithm or a medical parameter transmitted by the detection device, and then proceeds to a final encoding of the parameters and of the variable numerical identifier, said final encoding is an alphanumeric sequence which is the final result of all encrypted and concatenated codes together;
wherein the first server and the second server are connected via a secure network and operating as a client/server;
wherein the second server comprises a code database, a code receiving unit, and a correspondence determination unit, wherein upon said second server receiving of the final encoding by means of the code receiving unit, the said code receiving unit converts the final encoding in order to extract and generate a unique code, the code database storing the unique code generated by the code receiving unit, and the correspondence determination unit compare the code generated by the code receiving unit with the codes presents in the code database in order to determine a correspondence, or not; and
wherein said system performs the steps of:
a) illuminating a body part of a user by means of an infrared light;
b) capturing a first area of the illuminated part by means of a detector included in a detection device, having a unique identifier;
c) extracting a quantity of characteristics from the biometric information obtained by the sensor, by means of a extracting unit included in the detection device, and generating a vascular fingerprint, by extracting an image obtained from the first area;
d) normalization of said image according to a predefined standard and processing said normalized image;
e) segmentation of said normalized image and extraction of a tree structure and then search for a longest segment;
f) mathematical characterization of nodes of said segment;
g) matrix characterization of said nodes followed by an initial encoding;
h) application of an algorithm of the sequence matrix and matrix encoding of the sequence;
i) conversion of the vascular fingerprint, via an encoding algorithm, combining the device identifier with the extracted characteristics, into a variable numerical identifier, by means of a conversion unit included in the detection device;
j) transmit the variable numerical identifier into a first server;
k) generate the data by using a place, a date and anonymous information or a logistic parameter such as a coding of the reader and/or coding of a version and a number of the used algorithm or a medical parameter by means of a generation unit included in the first server;
l) proceeds to a final encoding of the parameters and of the variable numerical identifier by means of the generation unit, said final encoding is an alphanumeric sequence which is the final result of all encrypted and concatenated codes together;
m) integration of the final result in a multimedia messaging service (MMS);
n) backup the MMS;
o) transmission of the MMS according to the standard transmission protocol to a receiving unit integrated in a second server;
p) receiving and decoding the MMS with extraction of a unique code and deleting non useful metadata in the message by the means of the receiving unit;
q) inserting the unique code into a code database included in the second server; and
r) comparing the code generated by the code receiving unit with the codes presents in the code database in order to determine a correspondence or not by means of a correspondence determination unit included in the second server.
