The transformation of global air security in the technological era has undergone significant changes, adapting to digital advances and emerging security challenges. Technological innovation plays an important role in improving airport and aircraft security by using advanced security systems. One of the main aspects of this transformation is the implementation of biometric technology. The use of facial scanners at airports is becoming more common, shortening queue times for passengers’ identity checks. This system increases the accuracy of identity verification and improves the passenger experience. Additionally, many airlines and airports are adopting mobile application platforms to make check-in and boarding easier, thereby reducing physical interactions. Through the Internet of Things (IoT), interconnected sensors and devices help strengthen security. A concrete example is the use of sensors to monitor passenger luggage in real-time. It can detect suspicious items quickly, allowing security officers to take necessary preventive measures. Artificial intelligence (AI) is also an important component of air safety. AI algorithms can analyze big data to identify suspicious patterns. Applying machine learning in security processes enables better monitoring of passenger and object activity in the airport area, providing fast and precise analysis. Additionally, cybersecurity is becoming increasingly important in the digital era. As connectivity increases, the risk of cyber attacks also increases. Airports and airlines strive to protect passenger data and their information systems by imposing strict security protocols, including data encryption and regular audits of security systems. Training and awareness about security is also crucial. Human resources trained to recognize potential threats and use new technologies are the key to success. Continuous training programs ensure that security staff are always ready to deal with new modus operandi that could compromise aviation safety. International cooperation is also increasing in terms of exchanging information on security threats. Organizations such as ICAO (International Civil Aviation Organization) and Interpol play an active role in establishing global safety standards. This collaboration allows countries to share information about potential threats and strengthens the global security network. With the development of technology, new challenges arise. Drones, for example, can be a tool for terrorist attacks or disruption during flights. Having strict regulations regarding the use of drones around airport areas is very important to maintain flight safety. Various government policies also play a role in this transformation. Countries around the world are working to update their security regulations, with a focus on adapting to new technologies. This update aims to create a safer and more efficient aviation environment. Overall, the transformation of global air security is becoming more dynamic and sophisticated, driven by technological advances. From biometrics to AI, from IoT to international policy, all these elements contribute to creating a security system that is more proactive and responsive to existing challenges. This transformation not only increases the level of aviation safety but also increases passenger confidence in using air transportation.
