We need to analyze and discuss each of the “Daubert Factors” to understand the reasons of doubt on the acceptance of fingerprint evidence. The Daubert standard provides a rule of evidence regarding the admissibility of expert witness’ testimony during United States federal legal proceedings. Pursuant to this standard‚ a party may raise a Daubert motion‚ which is a special

Locard’s Exchange Principle and the use of Fingerprints: Edmond Locard (1877-1966) was a French scientist specialised in both medicine and law. Inspired by the work of Hans Gross‚ it was Edmond that created the concept that all objects of any material should leave traces of itself upon whatever it touches‚ even if it is the minutest amount‚ simply put as “Every Contact leaves a trace‚” Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such as

There are many specialized databases within the criminal justice system that have assisted in the advancement of crime solving‚ such as AFIS (Automated Identification Fingerprint System)‚ facial recognition‚ live scan‚ mobile data terminals and iris scans. However‚ as with any criminal justice advancement‚ there are some advantages and disadvantages with the use of technology. Criminal Justice Specialized Databases:

ABSTRACT: This paper presents a novel multi-level wavelet based fusion algorithm that combines information from fingerprint‚ face‚ iris‚ and signature images of an individual. The effectiveness of the fusion algorithm is experimentally validated by computing the matching scores and the equal error rates before fusion‚ after reconstruction of biometric images‚ and when the composite fused image is subjected to both frequency and geometric attacks. The complexity of the fusion and the reconstruction

person’s unique physical characteristics for authentication; these types of devices can use fingerprints or other physical characteristics of a person’s body. There are two types of fingerprint scanners‚ a static fingerprint and a dynamic fingerprint scanner. By doing research I found that I cannot recommend using these because of their cost and their reliability. While researching the cost of standard fingerprint biometric readers I found that most of them are relativity cheap. One can find a halfway

FOR EFFICIENT HUMAN RECOGNITION ABSTRACT This paper proposes the multimodal biometrics system for identity verification using four traits i.e.‚ face‚ fingerprint‚ iris and signature. The proposed system is designed for applications where the training database contains a face‚ iris‚ is developed through fusion of face‚ fingerprint‚ iris and signature recognition. finally combined into a total score‚ which is passed to the decision module. Multimodal system then compared to the enrollment
