Biometrics in Turkey
The use of biometrics, the measurement of unique human physiological and behavioral characteristics, has been incorporated into a multitude of technologies that are used on a daily basis to facilitate the identification or authentication of individuals. According to the EU General Data Protection Regulation (GDPR), “personal data resulting from specific technical processing relating to the physical, physiological or behavioral characteristics of a natural person, which allow or confirm the unique identification of that natural person, such as facial images or dactyloscopic data” means biometric data. Physiological characteristics include those identified from the fingers and hands, veins, face, eyes, ears, odor, and DNA. In contrast to physiological traits, behavioral characteristics (or a combination of both physiological and behavioral traits) also are increasingly utilized by biometric systems. Behavioral characteristics are generally dynamic and can be affected by various factors, including age, illness, or emotional state.
