Purpose of Digital Signature

At some organization, document multilevel signing is a necessary work everyday. Now, most organizations still sign documents by hand. Though we have electronic document, we cannot but printing, copying and looking for people for his signature and then keeping the paper file in archives. What is more, many electronic file can't be printed perfectly.

Often, we must sign file though we are in different cities. We can send file by email but can't add signature. If we post paper document and signing it before sending back, it is very inefficient.

Where is the advantage of electronic media if we do sign process by traditional way.

Like a written signature, the purpose of a digital signature is to guarantee that the individual signing the message really is who he or she claims to be. Also, it guarantee the message had not been changed from his or her signing action.

If facile and efficient digital signing can be done, we can achieve more efficiency and all advantages of electronic media again.
