What is ISO/IEC 20943:2017 ?

Title: Understanding ISO/IEC 20943:2017 and EN ISO 21247:2017

Introduction:

Biometric systems have become an essential aspect of modern technology, as they offer higher levels of security and accuracy compared to traditional methods. Finger images, in particular, are widely used in various biometric applications due to their unique characteristics. To ensure the quality of these images, ISO/IEC 20943:2017 provides guidelines for assessing the fingerprint image quality. However, understanding this standard can be challenging for those who are not familiar with the technical aspects of biometric systems. In this article, we will explore the details of ISO/IEC 20943:2017 and EN ISO 21247:2017, which are crucial for ensuring accurate and reliable biometric identification.

Understanding ISO/IEC 20943:2017

ISO/IEC 20943:2017, also known as Information technology - Biometric sample quality - Part 2: Finger image quality, is a technical standard published by the International Organization for Standardization (ISO). This standard provides guidelines for assessing the quality of finger images used in biometric systems. The standard defines the terms and concepts used in the biometric field, as well as the procedures for evaluating and comparing fingerprint images.

ISO/IEC 20943:2017 is divided into several parts, each covering a specific aspect of fingerprint image quality. Part 1 covers the general requirements for biometric sample quality, while Parts 2 to 5 cover the evaluation criteria for different types of biometric samples, including fingerprint images.

The standard provides detailed descriptions of the factors that affect fingerprint image quality, such as lighting, pose, and clothing. It also provides guidance on how to measure and evaluate fingerprint image quality using various metrics, such as the Mean Absolute Error (MAE) and the Pass Rate.

Understanding EN ISO 21247:2017

EN ISO 21247:2017 is a European standard published by the European Committee for Standardization (CEN). This standard is designed to ensure a consistent and clear communication of technical information among professionals in various industries. EN ISO 21247:2017 is divided into several parts, each covering a specific aspect of technical document writing.

The main purpose of EN ISO 21247:2017 is to establish a set of rules for writers to follow when creating technical documents, making it easier for readers to understand complex concepts and terms. The standard provides guidance on various aspects of document writing, such as the use of terminology, the structure of technical documents, and the presentation of technical data.

EN ISO 21247:2017 is based on the ISO 9126 standard, which is a set of guidelines for document design, formatting, and the presentation of technical information. By following the guidelines provided by EN ISO 21247:2017, writers can create clear and effective technical documents that are easy to understand and follow.

Conclusion:

ISO/IEC 20943:2017 and EN ISO 21247:2017 are important technical standards that provide guidelines for assessing and documenting fingerprint image quality. By understanding these standards, biometric systems can be designed and implemented more effectively, ensuring higher levels of security, accuracy, and reliability.
