After investing hundreds of man hours to create PowerPoint presentations and considering the sensitivity of the information that some presentations carry, there is an even greater need to protect them now. And, there are several ways in which PowerPoint presentations can be secured.
Using PowerPoint Password Security for Slides
Applying passwords to protect slides is the primary solution for PowerPoint security as it comes free with PowerPoint. However, it should be noted that using passwords to protect presentations is the least secure medium.
The drawback of PowerPoint password security is that it is unsuccessful in the prevention of unauthorized distribution of PowerPoint presentations, as there are several PowerPoint password crackers on the internet (largely free of charge) that can break the password protection in a short timeframe. So, the PowerPoint slides that are encrypted with a password to prevent modification can easily be decrypted and thus made available to all, as the passwords are easy to crack.
Digital Rights Management for Securing PowerPoint Files
Because only using passwords to protect your presentations do not solve the problem, you should consider Digital Rights Management (DRM). It is a safe and reliable medium to protect PowerPoint presentations which have been converted into the PDF format.
Converting PowerPoint slides to the Adobe PDF format is advantageous as one can restrict the editing and modifying of the content. This also means that PowerPoint does not need to use unstable technology, such as ActiveX or passwords, to view them.
All in all, PDF DRM security protects PowerPoint presentations from unauthorized decompiling, viewing, copying, sharing, modifying, saving, screen grabbing, and printing. This gives the author complete control over who can access the protected PowerPoint slides; the timespan during which the slides can be viewed, whether the slides can be printed; and whether the content should be watermarked when viewed and printed with the user’s identification information; and the ability to revoke presentations at any time.
With PDF DRM, you can also control the locations in which the users can view your PowerPoint presentations (in terms of the country and IP location). This ensures that the confidential material can only be viewed from a authorized place, for example an office location.
So, when we compare the built-in password security system of PowerPoint with the security offered to a PowerPoint presentation with DRM, it is clear that DRM outshines in numerous ways and offers maximum security features for your powerpoint slides. Ultimately, your enterprise can rely on a DRM solution to ensure the protection of your PDF presentations for clients as well as third parties as DRM maintains the integrity of the information (preventing alteration), thereby making it a safe and reliable way to view and exchange data between individuals.
We hope that the information shared in this article proves valuable to you in preparing secure PDF presentations. Feel free to share your feedback or inputs, if any.
