Hand Biometrics in Digital Forensics
Asish Bera Debotosh Bhattacharjee Mita Nasipuri
Digital forensic is now an unavoidable part for securing the digital world
from identity theft. Higher order of crimes, dealing with a massive database is
really very challenging problem for any intelligent system. Biometric is a
better solution to win over the problems encountered by digital forensics. Many
biometric characteristics are playing their significant roles in forensics over
the decades. The potential benefits and scope of hand based modes in forensics
have been investigated with an illustration of hand geometry verifi-cation
method. It can be applied when effective biometric evidences are properly
unavailable; gloves are damaged, and dirt or any kind of liquid can minimize
the accessibility and reliability of the fingerprint or palmprint. Due to the
crisis of pure uniqueness of hand features for a very large database, it may be
relevant for verification only. Some unimodal and multimodal hand based
biometrics (e.g. hand geometry, palmprint and hand vein) with several feature
extractions, database and verification methods have been discussed with 2D, 3D
and infrared images.
