You can convert a PDF document to an image document (e.g., TIFF/JPEG) and then convert it back to PDF. Doing this basically makes the file an efax.
There is a saying that goes something like - locks only keep honest people honest. I think that pretty much sums it up.
You have the opportunity, use it. With a certified PDF you can require the client to use the Adobe product, which respects security settings, to view your report. It's not that the report won't open in other PDF reading programs, just that the signature is no longer present. TAF does not say tampering with an appraisal is okay, but merely applies the obvious fact that a one person cannot control the actions of another.Heh, Adobe, I paid for your PDF product with an opportunity to create a secured document. So, where is that security ? I guess we all got hosed, didn't we ! (Except, Sofa Spud, her PDF's are "certified".) How sad, though, that one Q&A coming from TAF a few months ago gave some rather disheartening remarks and simply side-stepped the issue of report INsecurity. It's now o.k. for the client to "do whatever they want" with an appraisal after they receive it. Nothing is really sacred anymore.
