Athlete identification using biometric data is an advanced approach that utilizes unique physiological and behavioural characteristics of individuals. Parameters such as heart rate, ECG signals, body temperature and motion patterns are continuously monitored to create a distinct identity profile for each athlete. Unlike traditional identification methods, biometric-based systems provide higher accuracy and security. Wearable devices and smart patches enable real-time data collection during training and competitions. The collected data is processed using microcontrollers and analysed using intelligent algorithms. These systems can recognize athletes based on their unique patterns and detect any abnormalities in performance or health. Wireless communication technologies allow seamless data transfer to mobile applications and cloud platforms. Coaches and trainers can monitor athlete performance and identity remotely through dashboards. This method also helps in preventing impersonation and ensuring fair participation in sports events. Overall, biometric-based athlete identification enhances both security and performance monitoring in modern sports environments. In addition, biometric-based identification systems provide continuous authentication, ensuring that the athlete is verified throughout the activity rather than at a single point in time. This improves security and reduces the chances of identity fraud in competitive sports. The system also supports personalized training by analysing individual performance trends over time.
