Finger vein recognition techniques: a comprehensive review

Abstract

This paper discusses a comprehensive review of the previous research in the field of the finger vein recognition system with a focus on finger vein enhancements and features extraction advances and shortcomings. It starts with a general introduction of the biometric system followed by detailed descriptions on finger vein identification, and its architecture archival of it, which includes image acquisition, preprocessing of the image, feature extraction, and vein matching. This study focuses on related work proposed by previous researchers, issues in the field that originated from the related work, and a discussion of each of the issues associated and the proposed solutions to each of them. Next a comprehensive discussion on the advances and shortcomings of the existing techniques based on the qualities, capturing device, database, and feature of that quality is presented.Accurate comparisons between existing techniques are presented as tables to make it easy for new researchers to come up with advances and drawbacks of each technique without spending time on all existing research in this area.

Simplifying vein detection for intravenous procedures: A comparative assessment through near‐infrared imaging system

“…2 Despite advancements in clinical testing, laboratory diagnostics continue to come across numerous challenges in the preanalytical phase, including ordering, acquiring, and holding biological specimens. 3 Pre-analytical errors have consistently been reported as the prominent proportion of errors in earlier studies. These errors, frequently occurring throughout the collection of the specimen by phlebotomists, compromise the rectitude of the biological samples and result in inaccurate diagnostic information.…”

“…Enhancement for low-contrast images is calculated by given Equation (3). The purpose of this equation is to adjust the pixel values in a manner that accentuates lowcontrast regions, thereby improving vein discernibility.…”

“…To ensure patient comfort in pathology wards, the development of an error‐free pre‐analytical phase is crucial for the effective treatment of contagion 2 . Despite advancements in clinical testing, laboratory diagnostics continue to come across numerous challenges in the pre‐analytical phase, including ordering, acquiring, and holding biological specimens 3 . Pre‐analytical errors have consistently been reported as the prominent proportion of errors in earlier studies.…”

Data Encryption in Cloud Storage

“…Asymmetric keys form the foundation of Public Key Infrastructure (PKI), an encryption approach that needs two keys, one (public key) used in encrypting the plaintext and another (private key) used in decrypting the cyphertext [10], as shown in figure 2 below. This means that none of the keys can perform both functions.…”

“…This means that none of the keys can perform both functions. A public key is available to an individual in need of encrypting a particular information [10]. To decrypt the same information, the user should use the private key.…”
