This study examines the evolution of technologies such as facial and fingerprint recognition within Internet of Things (IoT) devices, analyzing market trends and user perceptions. The results show that some technologies are widely used because they are simple to incorporate into everyday devices, whereas newer innovations like iris or palm recognition are rarely used because of cultural and technical challenges. Due to issues with reliability and general concerns about data security, users show limited trust in these systems. Applications vary by industry. For example, biometrics are incorporated into luxury cars to improve security and also used in healthcare devices to precisely monitor health conditions. Along with the requirement to increase transparency in data processing, the technologies have to find a balance between security guarantees and convenience. In an age where technology influence every aspect of everyday life, the study suggests developing clear regulatory frameworks and encouraging collaboration between sectors to guarantee widespread and safe adoption while protecting user rights.76ensecuritybiometricsThesis
