Hello @Muhammad Shuja , Thanks for using Microsoft Q&A Platform.
Form recognizer works well in extracting information from forms and documents. In your use case it is more focused on identification of document is forged or not. But I don't think we can identify these using services like form recognizer/computer vision.
As per my knowledge the best possible solution is to use any external tools to identify the document is tampered or not. Then you can pass the document to the FR service to extract these data.
As we know Computer vision API has services that supports image analysis, Image moderation and Content Moderator. I would recommend you check these services and experiment with them.
I hope this helps.

Vasavi
