Abstract
This article focuses on the issue of poor-quality fingerprints in the field of dactyloscopy and biometric identification systems. Fingerprints, although considered a reliable identification tool, often show signs of degradation due to smudging, incompleteness, damage, or the influence of dermatological diseases. The text analyses individual types of fingerprint defects, their causes, and their impact on forensic and IT applications. Special attention is paid to the evaluation of fingerprint quality, both in the context of criminal investigation and within automated systems. The article also provides an overview of current algorithmic approaches to processing poor-quality fingerprints.
Keywords: Fingerprint, dactyloscopy, quality, usability, damage, dermatology.
