that a ticket is used by the same person from biometric security day to day Biometrics refers to metrics related to human characteristics. Biometrics authentication (or realistic authentication)[note biometric devices 1] is used in computer science as a form of identification and access control.[1] It is also used to identify individuals in groups that are http://www.biometric-solutions.com/glossary.php?term=Crossover%20Error%20Rate under surveillance. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals.[2] Biometric identifiers are often categorized as physiological versus behavioral characteristics.[3] Physiological characteristics are related to the shape of the body. Examples include, but are not limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, https://en.wikipedia.org/wiki/Biometrics iris recognition, retina and odour/scent. Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythm, gait, and voice.[4][note 2] Some researchers have coined the term behaviometrics to describe the latter class of biometrics.[5] More traditional means of access control include token-based identification systems, such as a driver's license or passport, and knowledge-based identification systems, such as a password or personal identification number.[2] Since biometric identifiers are unique to individuals, they are more reliable in verifying identity than token and knowledge-based methods; however, the collection of biometric identifiers raises privacy concerns about the ultimate use of this information.[2][6] The biometrics market was expected to be worth $13.8 billion in 2015.[7] Contents 1 Biometric functionality 2 Multimodal biometric system 3 Performance 4 History of biometrics 5 Adaptive biometric systems 6 India's national ID program 7 Recent advances in emerging biometrics 7.1 Operator signatures 7.2 Pro

In general, the performance of any biometric system (e.g fingerprint, voice, facial recognition, etc) is described using several metrics. FAR or False Acceptance rate is the probability that the system incorrectly authorizes a non-authorized person, due to incorrectly matching the biometric input with a template. The FAR is normally expressed as a percentage, following the FAR definition this is the percentage of invalid inputs which are incorrectly accepted. FRR or False Rejection Rate is the probability that the system incorrectly rejects access to an authorized person, due to failing to match the biometric input with a template. The FRR is normally expressed as a percentage, following the FRR definition this is the percentage of valid inputs which are incorrectly rejected. CER or Crossover Error Rate is the rate where both accept and reject error rates are equal. FER The Failure to Enroll Rate (FER) is the percentage of the population which fails to complete enrollment. EXAMPLE: let us assume we have a fingerprint biometric system. We also, have 100 users. During the enrollment stage 5 users where not able to enroll (e.g we can not establish a fingerprint signature/template for them). This means the system has a Failure to Enroll Rate (FER) = 5%. This means only 95 users can use the system. Then, during the testing out of the 95 users, 10 users were

Equal error rate is abbreviated as EER. Equal error rate (EER) is a biometric security system algorithm used to predetermines the threshold values for its false acceptance rate and its false rejection rate. When the rates are equal, the common value is referred to as the equal error rate. The value indicates that the proportion of false acceptances is equal to the proportion of false rejections. The lower the equal error rate value, the higher the accuracy of the biometric system. Equal error rate may also be referred to as a crossover rate or crossover error rate (CER).
