Scanning the veins of the palms is a biometric identification technology that takes advantage of the complexity of the pattern of blood flow and the layout of veins, which are highly individual characteristics that are nearly impossible to falsify.
To confirm his or her identity, a person only has to place his or hand on a scanner. Physical contact is not necessary, which means this process is very hygienic. The device sends the data to a database that automatically confirms the person’s identity.
The process involves collecting more than five million reference points in the veins of a person’s hand. The authenticity of the pattern of veins can be confirmed with complementary technologies, such as chips incorporated into smart cards that can process the identity confirmation in place of a computer. Additionally, the chips can store encrypted information about each person.
Bidi codes, a technology involving modules of information stored in a matrix of points or a bidimensional bar code, also make it easier to include encrypted data from the map of the veins on a person’s hand.
This technique makes it possible to confirm that the person who buys a ticket for a cultural or social event using a bidi code is really who he or she claims to be. Likewise, this can guarantee that a virtual purchase is actually sent to the buyer rather than another person, and it also authenticates access to restricted sites such as banks, businesses and security sites.
This method’s margin of error is extremely low and is universally applicable regardless of ethnic characteristics such as skin color. This technology marks an improvement over the use of passwords, identification numbers, or identification cards, which can be forgotten or stolen and are difficult to remember.
It has now been confirmed that three out of every four individuals use similar passwords for financial services, increasing the risk of password theft.
