Biometric authentication belongs in the areas of cybercrime and cybersecurity, digital society, and digital transformation. It is a modern method for securely protecting digital access or devices. It uses a person's unique physical characteristics, such as fingerprint, facial recognition, or iris scan, to confirm a person's identity.
Unlike classic passwords or PINs, biometric authentication involves using something that only the respective user possesses – their body. This makes it considerably more difficult for hackers to gain access, as biometric data cannot simply be guessed or copied.
A common example: Many people unlock their smartphone using their fingerprint or facial recognition. The phone checks whether the finger or face matches the registered user, and only then does it grant access to the device. Thanks to this technology, digital identities and sensitive data are better protected against theft or misuse. At the same time, biometric authentication simplifies access to digital applications, as there is no longer a need to remember or enter passwords.
