Biometrics refers to the identification of individuals based on unique traits such as fingerprints, face, iris, or voice. This technology, which has rapidly developed over the last few decades, has become an essential tool for enhancing security across various fields, from smartphone security to authentication in airports. Its widespread adoption illustrates how technology can improve security and efficiency while raising important questions about privacy and ethics. Biometrics proves that the unique characteristics of each person can be transformed into keys that unlock access to spaces, information, and services previously unimaginable.
