Types and applicability of biometric security

Biometric authentication certainly changed the level and the perception of identification and security. Although it seems as a product of modern technologies, biometrics dates back to the end of the 19th century. The first catalog of fingerprints was recorded in 1891 in Argentina, and it led to the development of mathematical method for identifying a person based on the fingerprints.

In modern day, there is much more than fingerprint-based identification when it comes to biometrics, due to the immense scientific development. Biometrics is applied in a variety of ways, and biometric security is on a growth curve. As connectivity become more complex across the globe, the need for additional and more complex security systems arose. This is when biometrics came onto the scene, and many security solutions involving biometrics have been developed and successfully applied so far.

Starting from the early fingerprint collection, biometrics developed into a complex and widely applicable science. There are different types of biometrics, and they include:

  • Visual biometrics – it includes the visual recognition of different body parts which are distinctive for each individual. Therefore we can confirm identity based on the recognition of someone’s iris, retina, fingerprint, facial features, ear shape, signature and so on.
  • Chemical biometrics – with this type of biometrics, the segments from DNA are analyzed for the sake of recognizing an individual.
  • Spatial biometrics – it includes recognizing the geometric features of an individual’s finger or hand, placed in the 3D environment.
  • Behavioral biometrics – it includes recognizing the specific features of a person’s behavior for the purpose of identifying. Walking style, gait and typing style can be analyzed. Signature can also be analyzed by behavioral biometrics when the movements during signing are analyzed instead of the visual characteristics of the signature.
  • Auditory biometric s – this type of biometric includes voice recognition, either for identifying the speaker, or for the sake of authentication or verification.
  • Olfactory biometric – in addition to all the features mentioned above, odor can also be used to identify an individual, and it is the area of olfactory biometrics.

Biometric security is already quite developed and it is still developing. While several decades ago it was something we could only see in movies, nowadays it is very much used and applied in a variety of ways, for different purposes. It is used for authentication and verification in various governmental, military and political institutions, in order to provide additional security. It has also raised criminal identification system on the new level, due to DNA recognition. Biometric security devices can be found on some airports and borders, and they provide additional security for the passengers and employees. Biometric security is also used on smaller scales and in everyday life. There are biometric safes and locks, biometric security systems for wireless money transactions, biometric security for accessing PC’s and much more.

Biometric security is a matter often discussed. Some praise it and encourage its use, while the others are skeptical and unsupportive. It is undoubtedly true that biometric security has both good and bad sides, but as long as it is used responsibly and the data are well kept, it should provide more benefit than harm.
