As an architect, I sometimes am asked to provide a "digital seal" to my pdf drawings to prove that I personally have created the file and to provide verifiable proof that the file has not been changed since I created it. It is to serve the same function as my embossed seal on a sheet of paper, symbolically saying, "this is mine, don't change it". Does Adobe Reader do this? I've read the documentation on digital signatures, but still unsure if AReader can apply a digital signature with verifiable proof of an unchanged document. I have found 3rd party software for a price that claims to do it, but if AReader will do it, I'd prefer to stay within a single program.

Not unless the file has been enabled by the creator using Adobe Acrobat.
