Biometrics - Research Paper Example Biometrics recognition is, therefore, the automatic recognition of users based on behavioral and physiological characteristics. Biometrics seeks to establish a users identity based on who she is rather what she possesses like an ID card or what she remembers like passwords. Biometrics gained popularity when body measurements were used by Alphonse Bertillon to identify criminals in the 19th century. It prompted law enforcer to take criminals fingerprints and store them in a database. The stored fingerprints could then be compared with fingerprints lifted from crime scenes. Biometrics are extensively used to identify criminals but has also gained use in employee clearance for sensitive jobs, determining fatherhood, forensics, identification of prisoners. Performance – refers to the achievable recognition speed and accuracy, the resources to be used in achieving the desired recognition accuracy and speed and the environmental and operational factors that affect the accuracy and speed. Different body parts are being used as a form of biometric recognition. Biometrics ranges from DNA matching, chemical biometric, visual biometric, eyes biometrics ( iris recognition, retina recognition ), finger geometry recognition, Hand geometry recognition, signature recognition and behavioral biometrics (typing recognition), vein recognition and gait. Deoxyribonucleic acid (DNA) matching is the process used in the identification of persons by their DNA profiles. DNA profiles are hidden sets of numbers that reflect an individuals DNA composition, which can also be used as a persons identifier. DNA profiling is different from a full genome sequencing that is used in parental testing and criminal investigation. Even though 99.9% of human DNA sequences are similar in every person, unless they are identical (monozygotic) twins. DNA matching uses repetitive sequences that are highly variable, known as variable number tandem repeats (VNTRs), particularly
