    This morning I read an article on the website Addicted Online (an addict to photography and technology) about the technology of biometric systems and its application in different areas of home security and everyday life. One of those applications we're already accustomed to is in mobile phones with access through facial recognition or fingerprints to our bank accounts or financial institutions where the security of ensuring it's truly us accessing the accounts is crucial.

    Biometric systems in mobile phones have revolutionized the way we secure and protect our devices and personal data. These systems work by uniquely identifying biological characteristics or specific user behaviors to authorize access. Facial recognition and fingerprint scanning are two of the most common biometric methods used today.

    The history of integrating biometric systems into mobile phones dates back to the early 21st century, with the first attempts to implement biometric recognition technologies in electronic devices. However, it wasn't until the mid-2000s that these functions began to gain popularity and be more widely incorporated into smartphones.

    Facial recognition uses advanced algorithms to analyze unique facial features such as the shape of the eyes, nose, and mouth to identify the user. This method became popular with the release of the iPhone X in 2017, which featured Face ID, a facial recognition system developed by Apple.

    On the other hand, fingerprint authentication has been present in mobile phones for a longer time. Motorola was one of the first brands to introduce this technology in their devices in 2011, with the launch of the Motorola Atrix. Since then, numerous manufacturers have followed suit, integrating fingerprint sensors into their smartphones, both on the front and back of the device.

    Regarding preference for one system over the other, it largely depends on user preferences and the specific implementation by each manufacturer. Some argue that facial recognition is more convenient as it does not require physical contact with the device, while others prefer the reliability and speed of fingerprint authentication.

    In the current market, several leading brands in mobile technology offer biometric systems in their devices. In addition to Apple with its Face ID, Samsung has developed its own facial recognition technology called "Intelligent Scan," which combines facial recognition with iris scanning for enhanced security. Huawei, OnePlus, Xiaomi, and other brands have also integrated biometric systems into their smartphones, providing a variety of options for users.

    In terms of performance and accuracy, it is difficult to determine if one system is inherently better than another, as this can vary depending on the device and specific usage circumstances. However, it is important for manufacturers to continue improving and refining these technologies to ensure the security and convenience of users in the future.
