Digital Holographic Technique Based Fingerprint Authentication for Criminal Investigation

EasyChair Preprint 3774

Abstract

In this age of highly advanced digital image processing, it is very difficult to store biometric details like fingerprint of a highly wanted criminal in a secure manner. Any digitally stored data can be forged, or the stored data can be easily destroyed or manipulated. Hence, a secure storage and easily recovered method need to be applied in such fields. Digital holographic data storage is one of the most secure storage methods available that can be used to resolve this problem. It provides a credible way in the fingerprint acquisition in the criminal investigation field. The accurate phase reconstruction is the unique advantage of digital holography compared with traditional fingerprint acquisition methods. In addition, digital holography has many significant advantages, such as simple, high accuracy and high resolution, moreover, it is a non-destructive method, does not undermine the on-site fingerprints. Also, some digital image processing can be applied to the original hologram and the reconstructed image, such as the image contrast brightening, filtering and so on. Therefore, it is possible to obtain a digital hologram with higher quality. Hence, digital holography can be used for secure storage and analysis of fingerprints in the criminal investigation field.

Keyphrases: On site fingerprints, digital holography, non-destructive
