Review of Biometrics: Palm Vein Recognition System

Biometrics refers to the identification of humans by their characteristics or traits. It is the science and technology of measuring and analyzing biological data. Biometric identifiers are often categorized as physiological or behavioral characteristics; among the features measured akin to face, fingerprints, hand geometry, handwriting, palm vein, iris, retinal, and voice etc. This paper discusses about palm vein biometric systems. The system is superior because it provides a nontransferable means of identifying people. The vein patterns are not easily spoofed, observed, damaged, obscured or changed. It is perceived as secure and integrated with "aliveness" detection. Palm vein authentication has a high level of authentication accuracy due to the uniqueness and complexity of vein patterns of the palm. The biometric data is based on human vein characteristics that stay constant throughout one's lifetime. A paper discusses about a palm vein technology, which gains much of the advantages over the traditional biometrics. The research states that human vascular structure is individually distinct. Even identical twins have different and distinct vascular patterns. The paper discusses about vein pattern recognition, imaging principles and image databases.
