Understanding Biometrics
Definition and Types of Biometric Authentication
A security procedure called biometric authentication uses a user's distinct biological characteristics to confirm their identification. This technique uses physical traits like voice recognition, iris patterns, fingerprints, and face features to authenticate users. Fingerprint and face recognition are the most widely used biometric identification methods in consumer electronics such as smartphones.
- The process of fingerprint identification, as demonstrated by Apple's Touch ID, entails analyzing each individual's fingerprint's distinct ridges and swirls. Touch ID was first introduced with the iPhone 5s in 2013. With only a simple touch of the sensor, customers can unlock their handsets, make purchases, and verify Apple Pay transactions.
- Face ID, Apple's facial recognition technology, verifies a user's identification by using a comprehensive three-dimensional map of their face. Itwas introduced with the iPhone X in 2017 and uses a dot projector and infrared light to produce an accurate face map for secure device unlocking and authentication for multiple services.
How Biometric Systems Work on iPhones
The safe and effective authentication of iPhone biometric systems is achieved by a combination of advanced software algorithms and innovative hardware components.
- Biometric data capture-specific sensors and cameras are examples of hardware components. While Face ID maps the user's face in three dimensions using an infrared camera, a flood illuminator, and a dot projector, Touch ID uses a capacitive sensor built in the power or home buttons to scan the fingerprint. Together, these elements enable the collection of high-resolution biometric data.
- Software algorithms are essential for handling and protecting this data. The biometric data that is collected during registration is transformed into a mathematical form and encrypted before being kept in the Secure Enclave, a specific security coprocessor built into the chip of the device. By doing this, security is improved by ensuring that the biometric data is kept separate from the primary operating system and applications. The system verifies identity when a user tries to log in by comparing the newly collected biometric data with the template that has been saved.
