screening

Screening is a security process used to guard against various hazards, including crime, fire, and sabotage. It involves measures to protect people, tangible property, and intangible information. Historically, airport security was minimal, but it evolved significantly in the 1960s due to politically motivated crimes like terrorism and hijacking.12

International conventions, such as the Tokyo, Hague, and Montreal Conventions, were established to address unlawful acts against civil aviation. These led to recommendations for enhanced airport security, including passenger and baggage screening using technologies like X-rays and magnetometers. Following the September 11, 2001 attacks, security measures intensified globally, with more thorough passenger and baggage scrutiny, and the implementation of advanced detection systems. Biometrics, which uses unique physical or behavioral traits for identification, has also become a common tool in security, including at airports for passenger identification.23
