The use of biometrics to identify people and protect information has become commonplace. We can notice the presence of the technology at work, public service centers, and ATMs. At home, when we unlock the smartphones by reading the fingerprints or the face, we also use biometrics.

In the companies, the use is increasing, and the biometric identification has been adopted in different processes, assuring security to the employees.

More efficient and secure than other ways to identify people, recognition based on physical characteristics facilitates routine activities that require the use of numeric passwords, avoiding fraud. In the midst of so many numbers, who never succumbed to the temptation to write down passwords in papers, diaries, or files to facilitate recovery in case of forgetfulness?

Biometrics is more convenient and secure than traditional passwords and card systems. The identifying element is part of the person. Since there is no password, it can not be forgotten, copied or falsified.





In a recent trend report conducted by Ericsson’s ConsumerLab, it became clear that consumers expect digital technology to increasingly operate in human terms, transforming the body into the primary user interface.

In the study, two out of three people interviewed believe that in just three years we will use body language, facial expression and touch to control consumer interaction with technological devices.

Today, it is already possible to find this technology in all sectors of industry and layers of society. Banks use biometrics to authorize financial transactions as withdrawals. To do this, they equip the ATMs with biometric sensors.

In the Brazilian public services, the most comprehensive case of its adoption is the electoral system. Electoral justice is registering, since the 2012 election, the biometry of voters to identify them on voting day.

In their private life, people have been installing biometrics to access their house, replacing the use of keys. There is also growing in the process of unblocking electronic devices, such as smartphones, by using fingerprint reading and facial recognition.

Biometrics offers several authentication options: fingerprint, iris reading, facial and vascular recognition. Among the most reliable solutions is the vascular recognition of the palm, which has been highlighted by precision. The technique has the lowest overall rate of false acceptance – a characteristic that determines how accurate the technology is and, consequently, the quality and security of legitimacy.

This quality is due to the complexity of the map of veins in the palm (which contains about 5 million reference points). The “information” is inside the skin – making it difficult to copy. The veins are mapped by light waves near the infrared.

In 2014, the German Defense Minister, Ursula von der Leyen, had her fingerprints cloned by a hacker from photographs taken with an ordinary camera. Ursula’s biometric identity would be protected by the use of vascular recognition since images of the venous structure are obtained only with specialized equipment.

Vascular recognition is a promise of safety in many industries, from schools, hospitals, airports, commercial condos, and houses. People with scarring on their hands, rural workers or one who has, for some reason, too much skin wear may have fingerprint authentication problems, which is no longer the case with the veins of the palm. Even among identical twins, the vascular pattern is different in all hands and remains the same throughout the individual’s life.
