Emerging latent fingerprint technologies: a review

Abstract

Information regarding state of the art technology is accessible by searching in a systematic manner, and is the preferred way of keeping up to date. In this review, we present the recent developments in the field of latent fingerprint detection. Recent developments in processing methods including optical, physical, and chemical methods, and sophistical instrumental analytical techniques are presented.

Detection of Acetaminophen and Its Glucuronide in Fingerprint by SALDI Mass Spectrometry Using Zeolite and Study of Time-Dependent Changes in Detected Ion Amount

“…Liquid chromatography mass spectrometry (LC-MS) was used to identify oxidation products of squalene [6], and methadone and its metabolites [7]. Matrix-assisted laser desorption/ionization (MALDI) [8][9][10], surface-assisted laser desorption/ionization (SALDI) [11], and desorption electrospray ionization (DESI) [12] were also used for imaging of fingerprints. Unfortunately, mass spectrometry has one drawback: as sample ionization is carried out, the sample is inevitably destroyed during measurement, leading to the loss of important fingerprint evidence.…”

Surface-enhanced Raman spectroscopic identification in fingerprints based on adhesive Au nanofilm

“…Fingerprint identication is widely used in access control, medical examination, forensic investigation and other elds. 1,2 The characteristics of human ngerprints are divided into three different categories, namely, the pattern of ngerprint lines; crossovers, ridge ends and so on; and individual sweat pores. 3 The minutiae of different levels have been considered to be the key point in the identication of ngerprints.…”

“…For latent ngerprint recognition, the use of specic chemical reagents or instruments enables the observation of colour or luminescence in the ngerprints, which provides an enhancement of the characteristic pattern of minutiae. 1 Read-out technologies that correspond to these methods, including colorimetric 6,7 and uorescence methods, 8,9 mass spectrometry, [10][11][12] infrared (IR) spectroscopy, 13,14 localized surface plasmon resonance (LSPR), 15 Raman spectroscopy 16 and so on, are employed in latent ngerprint identication. Conventional colorimetric methods rely on changes in the colour of latent ngerprints that have been developed with materials such as magnetic powders, 17 dyes, 18 ninhydrin 19 and cyanoacrylates 20 via chemical or physical reactions.…”

Towards a secure and automated platform for fingerprint-based electronic voting machine

“…In this project, biometric fingerprint impression is used for the purpose of voter identification and authentication. As the fingerprint impression of every individual is unique (Jain et al, 2016;Jasuja, et al, 2016) it helps in maximising the security. The arrangement demands the user to submit his fingerprint at the scanning module as an identity proof.…”
