Application of face verification based on Angular Margin triplet in train diagram management system

The data managed by the train diagram management system is related to the safe operation of the train, so how to ensure that the management system is not modified, added or deleted by unauthorized personnel is very important for the safe operation of the train. In order to ensure that only legitimate users can access the train diagram data, a face verification algorithm based on Angular Margin triplett is proposed, and is applied to the login verification and modification data verification modules of train diagram management system to realize the safety management of train diagram data.
