Imagine being asked to move your head using your phone’s camera when trying to access your online bank account. Or needing to confirm your identity through a real-time image capture before starting a remote exam. These scenarios reflect the concept behind Liveness Detection or proof of life.
Liveness Detection operates in the protection of personal data, integrity in biometric operations, and in increasing user confidence in digital services. By employing advanced Artificial Intelligence (AI) and Machine Learning (ML) algorithms, the technology verifies an individual’s liveliness.
In this post, we will understand how proof of life works and why it is so important. Keep reading!
How Liveness Detection works
The main objective of Liveness Detection is to prevent identity fraud. The technology combats deepfakes, in other words, image manipulations. In general, the process can be performed in two ways:
- Active Liveness Detection: verifies the natural movements of the person captured through any activities the user performs, such as nodding, smiling, blinking, among others.
- Passive Liveness Detection: analyzes the liveliness of the image without interacting with the individual. The technology detects unusual traits such as atypical lighting and skin textures that deviate from the standard.
It is worth noting that there is still no consensus on which is more efficient. This depends on the level of friction the solution may have with the end user. In BioPass ID, performance-based passive Liveness Detection is used, a technique that does not require active actions. The algorithm looks for unnatural traits in the images to verify if it corresponds to a living person.
Key applications of Liveness Detection
In Brazil, several sectors already use proof of life to ensure the security and integrity of onboarding and matching operations. Among the main ones, the following stand out:
Education
In educational institutions, Liveness Detection can be used in distance learning. Through the technology, it is possible to monitor student presence, validate access to online classes, and track frequency in mandatory activities.
Health
In the health area, proof of life technology is used to validate patients' presence in online consultations, authorize exams, and allow access to restricted areas. It also helps verify the identity of professionals and service providers.
Finance
In the financial sector, proof of life can be used from accessing the bank's app to requesting money transfers. Liveness Detection, combined with Face Match, validates the identity of the person performing the operation.
Digital retail
In digital retail, Liveness Detection can be used to prevent fraud during user login validation and payment authentication during purchases. Proof of life also enhances the customer experience by enabling identity confirmation with a single biometric capture.
How to perform proof of life
Many organizations still do not fully understand the benefits of Liveness Detection, such as fraud prevention and strengthening security in digital processes. This happens, in part, due to a lack of knowledge about how the technology works and how to integrate it into existing systems.
Let’s see in practice how BioPass ID’s Liveness Detection works. Check it out:
- First, the user must capture a photo.
- Next, if the image is with a good quality, the technology will select it for biometric analysis. If not, the individual is asked to repeat the capture.
- Subsequently, after the biometric analysis, the liveliness check is performed. If successful, the biometric match is made.
To illustrate, follow the demonstration below:
1. Biometric capture
2. Image submission
3. Successful verification
Now, see what would happen in the case of a fraud attempt.
1. Biometric capture
2. Image submission
3. Verification with fraud detection
BioPass ID is fully customizable, allowing the implementation of processes according to specific needs. The intuitive and easy-to-navigate interface enables a simpler and more efficient identity verification.
BioPass ID Liveness Detection
Liveness detection is important to ensure security in operations across any sector. With the advancement of digitization and the adoption of new technologies, the demand for more secure services has grown, especially in the fight against fraud.
For this reason, when selecting a facial recognition provider, it is essential to consider the accuracy of the technology. BioPass ID, for example, guarantees more than 99% accuracy in biometric operations. In addition to Liveness Detection, the solution also includes Face Match and Capture SDK features that ensure user legitimacy. It also validates the identity of individuals and protects systems from fraud.
