Making my code detect my face and recognize me from any other person

I'm working on (streamingFaceRecognition) code wich can do the detection and recognition process, I want to edit the code such that if a person was detected by the camera and it wasn't me, it take snaps a picture for that person. ( code below )

Explicit explanation:

1- Streaming face recognition code is already running and my picture saved in the data

2- taking a picture for any person that is detected by the camera (except me) [ The idea is to make the program recognize me from others]

3- Saving the picture or its data in a location

Here is the code:

Is cross correlation the solution? And how can we solve this problem
