Green tick mark or yellow question mark on digitally signed pdf.

Hi everyone,

I am using a digital signature to sign a pdf document. But I don't see the green tick mark in the signed document.  Instead, I see an Adobe acrobat symbol as watermark.

Questions,

the appearance of the green tick mark when the signature is valid is something thats provided by Adobe or its when the document is signed and with whom its signed?

Thanks,
Raj
