Abstract

The intelligent identity authentication method and system for departing passengers at airports uses facial recognition technology to collect facial images at airport security checkpoints, and uses ID card readers to automatically verify the authenticity of ID cards and automatically identify ID card numbers. It also employs automatic facial image capture, compression, and confirmation technology to achieve real-time alerts for criminal suspects passing through security, ensuring that the control of criminals is not limited by time or human intervention. At boarding gates, facial recognition technology is used to completely prevent the switching of boarding passes. The system also utilizes large-scale database technology to store historical data on passenger departure dates, flight numbers, ID card numbers, and facial images for long-term tracking and statistical analysis.
