Biometric Types Comparison


Biometrics is the automated system that can identify an human being by measuring their physical and behavioral uniqueness or patterns, and compare it to those on record. There are different types of biometrics which can identify fingerprints, face, iris, palm vein prints,voice of an individual.

Biometric broadly classify in two categories 1.Physiological characteristics and 2.Behavioral characteristics.

Physiological characteristics means shape of the body e.g it includes fingerprint, face recognition, Palm vein print, iris recognition and lot more and Behavioral characteristics are related to the behavior of a person, e,g typing rhythm,gait, and voice and lot more

Biometric Advantages are as follows:

  • No need to remember password.
  • High Security
  • Offers mobility
  • Positive and accurate Identification
  • Impossible to deceive
  • Non transferable
  • Safe & user friendly

As we have seen various biometric types, we can see their features in the tabular format

Characteristics Details :

  • Speed :Relative time required to collect/match (1:1).
  • FTE Rate: Failure-to-enroll, based on all social, environmental, and technical factors.
  • Standards: Status, maturity, and completeness of agreed technical standards for collection, storage and matching.
  • Uniqueness:Probability of multiple “good matches” within a population.
  • Maturity: Degree to which fundamental science is fully understood/developed.
  • Durability: Susceptibility to wear, deformation, injury.
  • Invasiveness: Enrollee perception.
  • Overtness: “Overtness” means that end users are aware that biometric data is being collected and used, and acquisition devices are in plain view.
  • Range: Capture Distance
  • Template size: template size in bytes
  • Age range: Degree to which enrollee age imposes limitations on collection, accuracy, etc.
  • Skill:Required of personnel collecting/matching samples.
  • Accuracy:Combination of FTE rate, usability and quality of sample.
  • Universality :Degree to which there is variance based on demographics, environment or other factors.
