Proof of Life: meet Liveness 2D V2

Even though 93% of Brazilians consider biometrics to be the most secure technology, it is common for some people to still have misgivings about the topic. Biometrics is applied almost exclusively to curb identity fraud, i.e. to prove that you are yourself. And there is even a specific name for this: it is liveness detection or, as the function itself suggests, proof of life. 

In 2022 there were more than 3 million attempts of identity fraud, according to Serasa Experian. This data is alarming and worries both users, who fear identity theft, and companies, who want to provide a better experience to their customers.

In this article we will explain why Liveness and biometrics are the technologies used to increase security in digital processes involving sensitive data - such as our identity, and how to implement them in your business.

How Liveness works as proof of life

Whether in bank accounts, registration of information on digital platforms, attendance control or monitoring of live classes, as is the case with certification processes in driving schools, doubts and fears about data security are common.

Thus, services that guarantee the confirmation of a person's identity, proving that the person is the real person and not a photo or any other kind of simulation that circumvents the system are well seen and widely implemented to this kind of processes. 

Liveness works to answer questions and mainly to ensure that the registration of biometric images and captured documents are real. And this is why the technology is used one of the main federal agencies, the National Institute of Social Security.

In the article Liveness: the technology used by the National Social Security Institute to prevent fraud, we see that the technology is used by the public service in a procedure known as proof of life. The procedure must be done annually to prove that a long-term beneficiary of the National Institute of Social Security is still alive.

To do so, it uses a system of comparing information in different databases to ensure identity. This is one of the features of liveness technology. 

In addition, ensuring that verification, registration, and access to confidential information are not violated are some of the major concerns of the technology, since data is one of the most precious assets that a business can have nowadays. 

The information control is not the only point to be safeguarded by those who hold the data. The way it is accessed matters enormously, since if a barrier is not created to attacks, anyone can pass themselves off as someone else and access the data. 

As well as the National Institute of Social Security, several industries can apply the technology and benefit from liveness. 

Understand, now, how to apply it in your business with BioPass ID.

Validation of people and documents in Liveness 2D V2

Liveness 2D V2 is part of the Multibiometrics API package of the BioPass ID cloud biometrics and AI platform. In its second version (V2), the technology works as follows: a face image is captured and analyzed for quality to enhance the face liveness analysis process. 

The image needs to be captured at the time of registration to ensure that the person is who they claim to be or that the captured document is genuine. This live registration acts as a second layer of validation of the identity under analysis, delivering information that proves liveness. 

The passive mode of Liveness 2D registration does not ask the person to gesture in order to prove that they are alive. During image registration, the process occurs quickly and simply, without explicitly indicating that a validation is being performed.

But how can a simple capture ensure liveness?

Liveness 2D technology goes far beyond image capture. 

Before even determining whether the image is an attack or not, the capture goes through a qualitative analysis to add another security layer that aims to determine qualitative aspects, such as:

  • Focus: the image must not be blurry or fuzzy.
  • Brightness: the image must have adequate brightness. Not too dark and not too bright.
  • Visibility of the face: the subject's face should be completely visible.

These requirements contribute to a better accuracy of the analysis and ensure that the captures take place in minimally controlled environments, allowing the user to perform the procedures from anywhere, safely and quickly, without worrying about the result of the operation.  

Thus, the relevant quality factors, such as points on the face or document are analyzed and the image quality is sufficient to prove the vividness and hinder attacks.

How to implement Liveness 2D V2?

The use of Liveness 2D V2 is indicated for the authentication of any process that needs to validate the liveness of a person or document registration, in digital onboarding processes involving: 

  • Driving schools.
  • Attendance validation.
  • Confirmation of class attendance. 
  • Registration of digital identities. 
  • Banking processes. 

The implementation of this service is done by using the Multibiometrics API - Liveness 2D V2 in a very intuitive and fast way, so that it is up to the user how the project will be developed. In addition, the Multibiometrics API package supports all types of languages.
