Hou I can add a face recognition in my rails app ?

I have one app where i have a scaffold with a register of peoples with photo, but for me search if the people have your datas registered in my system i need use face recognition for read face in web camera and read the photos of database and if search the people return your personal datas, how i can make this in rails ??? Im begginer with rails.
I need to implement this as soon as possible in my system, but I couldn't find anything on the internet very specific.

You can handle the heavy lifting by using a background job that extracts embeddings from each uploaded photo and stores them, then compare vectors on each search. I’ve used https://face2social.com/ before to quickly test whether my embeddings were good enough, and it helped me spot bad images early. A simpler model like FaceNet or InsightFace usually plugs into Rails pretty smoothly via a small Python service.
