Hello every body, I creat a document with Word and insert my signature with a file .bmp
When I creat pdf and send to someone just for reading he can copy my signature. How could I protect my signature.
Don't send the PDF file.
Create a document with Word, convert it to PDF, open it with Acrobat (Reader/Pro/Standard) then sign it and send it.
So anything inside cannot be edited nor copied.
You can't, if someone can see your signature then they can copy it. But you can make it more difficult. For example, merging the signature with background content on the document. With a PDF this would be converting it to an image.
It is better to use Certificates and Digitally Sign a document. This cannot be copied. If you want your actual signature, I suggest covering it with the digital signature which is a box with text of name, date, etc.
