Hi AI builder community,
I'm currently developing a cloud flow using power platform prebuilt text recognition AI builder model, which extract all recognizable information from PDF document into text.
Now I got a requirement to check whether a document is signed or having a validation stamp on it through the cloud flow,
is there a way at power platform available to indicate directly when a signature or stamp provided in the PDF?
For now, I can only think about indicating whether a signature or stamp is provided by analyzing the text output from prebuilt text recognition AI builder ->exam whether there are certain key words of the stamp is detected / or whether there are (signed) value after certain key words, ex. 'To Sign'.
Any advices are welcome, thanks!!
Hi @devsyw ,
There's no signature detection per say but what you could do is a extract all the text using the AI Builder Text recognition model and look for a specific string that would tell us if the document contains a signature.
Hope that helps!
