PowerPoint (PPT)

There are two different approaches to protect Powerpoint files.

Using the PowerPoint Viewer

Using the PowerPoint Viewer is easy to handle and adds the same protection level like protecting EXE files. The PowerPoint Viewer is provided for free and is included in the main PowerPoint installation.

•	All animations including video and audio are supported

•	No conversion necessary

•	PowerPoint Viewer is free

•	One PPT can invoke another PPT (Link from PPT A to PPB - tested with Office 2007)

•	Not the same strong protection level like a converted flash file will offer

•	No menu can be added to select different presentations

•	As all files have to be extracted from a database, the size for the project should not exceed 100 MB. You can protect multiple PPT files with each 100 MB in size by splitting the project into several databases

•	Printing can not be disabled (always enabled)

•	Macros inside PPT are not supported

PPT Conversion to Flash

The PPT files can be converted into flash and therefore are protected with the highest security level, which Multimedia Protector offers for flash files.

•	Highest protection level

•	A menu can be used to start different presentations

•	The size of the complete project does not matter as files are loaded into memory only when required

•	Printing can be enabled or disabled

•	Some special animation effects will not work with converters

•	The file has to be converted

•	The converter is not free

•	Macros inside PPT are not supported

What is the difference between Multimedia Protector and the Microsoft IRM (Information Rights Management) system in Office 2007?

The IRM system in Office 2007 allows to specify security options per user. You need a server to handle the user information and each user must install the IRM Client on his PC. This is typically a possible approach to protect a document inside the own company. If the document should be distributed, the restrictions to have a connection to the IRM server and to install the IRM client should be considered. Multimedia Protector protects PPT files without the need to install an additional software or to have an Internet connection.
