What is EN ISO 19794-6:2019?

EN ISO 19794-6:2019 is a technical standard document that provides guidelines for the biometric data interchange format (BDIF) used in the exchange, storage, and verification of fingerprint data. It is part of the International Organization for Standardization (ISO) 19794 series, which defines various aspects of biometric data interchange.

Importance of EN ISO 19794-6:2019

This technical standard plays a crucial role in ensuring interoperability and compatibility among different systems and devices that utilize fingerprint biometric data. By following the guidelines outlined in EN ISO 19794-6:2019, organizations can reliably exchange and process fingerprint data with confidence in data integrity and accuracy.

The importance of EN ISO 19794-6:2019 extends beyond system and device compatibility. It also addresses privacy and security concerns related to biometric data. The standard ensures that proper measures are taken to protect sensitive information during transmission, storage, and processing.

Main Features of EN ISO 19794-6:2019

EN ISO 19794-6:2019 specifies the structure and content of an interchange record (IR), which is the fundamental unit of data exchange. The standard defines the format, encoding rules, and data elements required for exchanging fingerprint data in a standardized manner.

The document outlines the use of multiple record types to accommodate different scenarios and requirements, such as capturing rolled and flat fingerprints, specifying impression types, associating quality values, and embedding other relevant information within the IR.

EN ISO 19794-6:2019 also provides guidance on compression techniques for reducing the size of fingerprint images without significant loss of detail. This enables efficient storage and transmission of biometric data while maintaining an acceptable level of image quality.

Conclusion

EN ISO 19794-6:2019 is a technical standard that ensures the secure and standardized exchange of fingerprint biometric data. It promotes interoperability, data integrity, and privacy by establishing guidelines for data format, encoding rules, and data elements.

By adopting EN ISO 19794-6:2019, organizations can confidently implement biometric systems and devices knowing that they comply with international standards, uphold privacy rights, and provide reliable and accurate processing of fingerprint data.
