The accuracy of biometric identification systems is directly linked to the quality of the data collected. Photographs with poor lighting, out-of-focus images, faces partially covered by accessories, and users looking away increase the risk of inconsistencies during capture. These issues can block authorized individuals or, in more critical situations, allow the validation of unauthorized users. Additionally, companies that fail to comply with the international ISO/IEC 19794-5 standard expose their systems to vulnerabilities, legal risks, and imprecise data.
To mitigate these challenges, a robust solution is the BioPass ID Quality API. Designed to qualify biometric data during capture, the tool ensures compliance with technical and regulatory requirements, enhances authentication system performance, and reduces operational failures.
In this article, we will show why choosing the BioPass ID Quality API is a strategic decision and share best practices for integrating it into your business systems.
Let's take a look!
Security and accuracy with BioPass ID’s Quality API
The tool was designed to verify whether biometric records, such as facial and fingerprint images, meet the quality requirements for use in authentication and identity validation. When data falls below the standard, the risks of improper blocks, recognition failures, and unauthorized access increase.
The Quality API addresses the problem at its root and enhances the reliability of biometric operations. Through the facial compliance verification feature, it is possible to evaluate 22 criteria, such as sharpness, absence of facial obstructions, proper angle, among others.
By adopting the REST standard, the tool integrates with existing corporate systems without requiring additional infrastructure. It also operates independently of the device and can be applied to web environments, mobile applications, or back-office systems.
Main features of the Quality API
The Quality API package brings together resources that reduce friction in facial integration, ensure the compliance of biometric images, guarantee interoperability between systems, and standardize stored records. Learn more below:
Facial cropping
Generates a Face Token, meaning a standardized and aligned version of the captured face, ready for use in biometric authentication processes. Instead of storing the original image, the system extracts and saves the aligned face according to ISO standards.
Standardization ensures uniformity of format and proportions, regardless of the equipment or the angle of the photo. The process facilitates comparisons and improves accuracy in facial recognition systems, such as biometric login or validation in digital enrollment processes.
Facial background remover
Removes surrounding elements from the image and preserves only what is relevant to biometrics, which is the user’s face. Whether at home, in transit, or in environments with complex visual backgrounds, the facial background remover keeps the focus exclusively on the face.
Fingerprint quality check
Performs an automatic analysis of the captured fingerprint image to verify whether it is sharp and suitable for use. Only images that meet the minimum quality level are accepted, which reduces failures and rework.
Facial compliance verification
Evaluates whether the captured facial photo complies with the ICAO standard, widely used in official documents such as passports. The analysis ensures centered images with proper lighting, a neutral background, and no obstructions, reducing the likelihood of rejection or authentication failures.
The Quality API includes internationally certified features from renowned institutions such as the National Institute of Standards and Technology (NIST) and FVC-onGoing.
Case study: Quality API in Certfy identity issuance
The BioPass ID Quality API is used in Certfy, a complete digital identity platform adopted by several Brazilian states to support the issuance of official documents. During citizen service, the automatic verification of image quality occurs in real time and ensures the storage and exclusive use of qualified biometric records. The results achieved were:
- High volume of issuances: the API enabled the issuance of more than 18 million official documents.
- Reduced rework: significant decrease in registrations rejected due to low image quality.
- Increased security: compliance with international standards (ISO/IEC 19794-5, NFIQ), making fraud more difficult.
- Faster service: shorter waiting times for citizens and greater efficiency for the issuing authority.
With the Quality API, Certfy ensured the adoption of a strict standard for captured images, which reduced failures, eliminated unnecessary repetitions, and improved user recognition.
Efficient biometric capture depends on quality from the start
Throughout this content, we highlighted the importance of qualifying biometric data to ensure security, efficiency, and legal compliance in digital identification processes. We also showed how failures in image capture harm the user experience, increase the risk of fraud, and expose institutions to legal sanctions.
The BioPass ID Quality API is a robust and flexible solution capable of automating quality analysis, standardizing records, and ensuring that only reliable biometric data is used. With advanced features, simplified integration, and proven results in large-scale operations, the tool provides the necessary support for organizations seeking excellence and innovation in biometric authentication.
