A digital signature or ID is more commonly known as a digital certificate. Digital IDs help to validate your identity, and they can be used to sign important documents including PowerPoint presentations. Digital certificates are typically issued by a Certificate Authority (CA), which is a trusted third-party entity that issues digital certificates for use by other parties. You can also purchase a digital certificate from many commercial third-party certificate authorities or obtain a free digital certificate. There are many institutions, governments, and corporations that can also issue their own digital certificates.
As far as PowerPoint is concerned, a digital certificate is necessary for a digital signature because it provides the key that can be associated with a digital signature. Digital certificates make it possible for digital signatures to be used as a way to authenticate digital information. In subsequent tutorials of this series, we will explore how you can acquire a digital certificate or create your own digital signature. In this tutorial we will show you how to add a digital signature in PowerPoint 2010:
- Launch PowerPoint, and open any existing presentation that you want to add a digital signature to. If you made any changes to your slides, do save your presentation before you proceed further.
- Access the File menu, and choose the Info option to get to Backstage view, as shown in Figure 1 below. Thereafter, select the Protect Presentation option to bring up a small drop-down menu (see Figure 1 again). From the drop-down menu select the Add a Digital Signature option, highlighted in red in Figure 1 below.

- This opens a message window, as shown in Figure 2.

The message windows provides you with two buttons: Signature Service from the Office Marketplace and OK. Clicking the Signature Service from the Office Marketplace button opens a web page as shown in Figure 3. Here you can find services that issue digital IDs for your use, or services that complement the 2007/2010 Microsoft Office system and use digital IDs. You can check out the services listed within this web page, and choose any service based on your requirement and budget.

Note: Although the web page lists the services that complement the 2007 Microsoft Office system, the same list works for Microsoft Office 2010 as well.
- Clicking the OK button within the PowerPoint message window (see Figure 2) opens the Get a Digital ID dialog box (see Figure 4). Within this dialog box you'll get two options: Get a digital ID from a Microsoft partner, and Create your own digital ID.
