Course Introduction
A Digital Signature is not a digitized signature (an electronic scan of a signature). While a Digital Signature helps prove your identity and a drawing's authenticity, a digitized signature is nothing more than an electronic version of your own signature inserted or attached to a PDF document. It can be forged and copied, and has no tangible security value. Digital Signature is a widely used term that uses a Public Key Infrastructure (PKI) certificate known as a Digital ID. PKI is inseparable from digital certificates. A PKI is responsible for issuing certificates, ensuring the distribution of these certificates through a directory, and validating certificates.

If you still experience any difficulty in downloading or opening this file, you may need to close some applications or reboot your computer to free up some memory.
Course Summary
When delivering PDF files by email, FTP, or Internet, a Digital Signature should be applied to the document. This requires the user to obtain a 3rd party Digital ID to apply a Digital Signature to PDF files. By applying Digital Signatures to documents, the signer is assured the document has not been changed, if returned.
