PowerPoint (PPT)

There are 3 different approaches to protect PowerPoint files.

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)

•	A menu can be used to start different presentations

•	Printing can not be disabled (always enabled)

•	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

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

•	Macros inside PPT are not supported

•	Needs Office 2003 or newer versions

Only if you want to disable printing or the security level is very important, select one of the following options.

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

•	Printing can be enabled or disabled

•	Animations are available

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

•	A menu can be used to start different presentations

•	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

•	One converted Flash file cannot invoke another Flash file (Link from PPT A to PPB)

PPT Conversion to PDF

•	Highest protection level

•	Printing can be enabled or disabled

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

•	The PDF Viewer is included in Multimedia Protector

•	A menu can be used to start different presentations

•	No animations - only static text

•	The file has to be converted

•	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.
