Integrity and authentication on signature signing (image signing)

I am using GroupDocs.Signature and I want to know how Integrity and authentication works on a signature signing (image signing).
Or is there any guarantee for integrity and authentication, or it just puts a signature-image on a document?

How can I Verify the document for signatures in case of Image signing(signature signing)?

Here I found verifying for some types, but I didn’t find it for signature signing?

Yes, it’s just a signature-image.
However, we have a QR-code with ability to insert encrypted data in there. It means that QR-Code text is not readable and could be extracted only by Signature App with known keys/salt/password combination.
Have a look at following resources:

I got it, thank you very much!
