Digiti Sonus: Advanced Interactive Fingerprint Sonification Using Visual Feature Analysis

This paper presents a framework that transforms fingerprint patterns into audio. We describe Digiti Sonus, an interactive installation performing fingerprint sonification and visualization, including novel techniques for representing userintended fingerprint expression as audio parameters. In order to enable personalized sonification and broaden timbre of sound, the installation employs sound synthesis based on various visual feature analyses such as minutiae extraction, area, angle, and push pressure of fingerprints. The sonification results are discussed and the diverse timbres of sound retrieved from different fingerprints are compared.
