can anyone give a very beginners guide to how using digital signatures to sign word documents, is any better and proves more integrity than physically signing a document, or scanning a copy of your signature and inserting it into each word document. What benefits do dig signatures to to prevent users fraudulently signing a document impersonating another's signature? Is there no opportunity to fraudulently digital sign a word document? as there would be physically faking a signature?
And what costs are involved with digital signatures, do you pay per signature, or is it a one off payment and you can sign as many documents as you chose?
