Connecting a webpage to an OCR engine

I am working on a website that at one point will ask for a user’s first name, last name, a photo ID, and an email address. Now I need to validate that the photo ID has actually the same name as the first and last name entered, which means some OCR or image processing needs to happen. I do not want this to be done via an external API cos I have to guarantee to users that the photo will remain within be site and not exposed to other third parties. I don’t really know best way to do this, I was thinking maybe some java application?? Any help would be appreciated.
