Biometrics before was not the same in the present. The method to classify an individual’s identity was through body measurement. Despite being manual, the method was the most systematic way to authenticate an identity.
In the 1800s, biometric had its official record, and fingerprinting followed later as a more advanced authentication of a criminal’s identity. It also worked as a symbol of signature for contract signing.
After that, biometric technology exponentially grew and developed the concept of facial recognition in the 1960s. This automated process became the most used by law enforcement. The Federal Bureau of Investigation funded this biometric technology as it created sophisticated sensors for data extraction and biometric capture. With this concept, facial recognition technology analyzes facial features, which is also present in smartphones today, aside from fingerprint recognition.
Then, the concept of speech recognition technology was born in the 1980s. The National Institute of Standard Technology formed a speech group that will serve as the foundation of the speech commands and recognition that advanced technology offers today. With the voice command and response, people are now taking advantage of the feature. Additionally, NIST developed the idea of iris recognition as they discovered the uniqueness and beauty of blood vessel patterns in the eyes which could be a perfect basis for authentication.
Furthermore, in the 2000s, the scope of biometrics did not only limit to function for large corporations or government settings. Biometric technology had gone available for the entire United States. Significant events also use biometrics to detect the identities of the attendees and staff.
In the present, biometric continues to evolve and will continuously change in the future. With people’s smartphones today, the concept of fingerprint and facial recognition resides in their features. Also, there are other kinds of gadgets using speech recognition that works well for convenience.
Also, for electronic payments, passwordless authentication UX has become the best method to identify the user. It ceases the concept of inputting passwords or PINs to access their account. Moreover, FIDO2 passwordless authentication solves the password dilemma and provides excellent convenience for electronic payments and other means of online banking.
LoginID’s passwordless solutions are FIDO and UAF certified. Users can easily integrate APIs and
SDKs, providing businesses and consumers all of FIDO benefits without complications.
