Description: An ocular biometric device is an advanced system that uses ocular patterns, such as the iris or retina, for the identification and authentication of individuals. These devices are part of the wearable category, meaning they can be worn directly by the user, often in the form of glasses or contact lenses. Ocular biometric technology is based on the uniqueness of each person’s ocular patterns, making it a highly accurate form of identity verification. In addition to their ability to identify users, these devices can offer additional functionalities, such as health data collection or secure access to digital information. The growing concern for security and privacy has driven the development and adoption of these devices, which promise not only to enhance security in various applications but also to facilitate interaction with technology through more intuitive and less invasive authentication methods than traditional passwords.
History: Ocular biometric technology began to develop in the 1980s when researchers started exploring the use of the iris as a unique trait for identification. In 1994, Dr. John Daugman patented an algorithm for iris recognition, marking a milestone in the evolution of this technology. Since then, there have been significant advancements in the accuracy and speed of ocular recognition systems, driven by the development of more sophisticated algorithms and improvements in image capture technology.
Uses: Ocular biometric devices are primarily used in security applications, such as access to restricted facilities, border control systems, and authentication on mobile devices. They are also being explored in the healthcare field, where they can assist in monitoring ocular conditions, verifying patients’ identities, and collecting biometric data for clinical studies.
Examples: An example of an ocular biometric device is the iris recognition system used in some airports for passport control. Another example is smart glasses that incorporate ocular recognition technology to unlock devices or access personalized information.
