Zusammenfassung
Currently, it is a largely accepted fact that biometric sample quality is the most determinant
factor to achieve high recognition accuracy in biometric systems. However, even in extensively
researched characteristics such as fingerprints, there is still a lack of evidence on how quality evolves
throughout the life of an individual. For instance, how does the quality of children fingerprints compare
to that of adults or elders? Do these changes imply any age limits for the use of fingerprints
with current technology? The present paper addresses this key problem based on a database of over
400K fingerprints coming from more than 250K different fingers. The database was acquired under
real operational conditions and contains fingerprints from subjects aged between 0 and 98 years.
Such a unique set of data has allowed us to analyse for the first time how fingerprint quality changes
through life.
