Use the OpenOffice.org – Security page to choose security options for saving documents and for opening documents that contain macros.
Choosing security options for opening and saving documents.
Security options and warnings
If you record changes, save multiple versions, or include hidden information or notes in your documents, and you do not want some of the recipients to see that information, you can set warnings to remind you to remove this information, or you can have OOo remove some information automatically. Note that (unless removed) much of this information is retained in a file whether the file is in OpenOffice.org’s default OpenDocument format, or has been saved to other formats, including PDF.
Click the Options button to open a separate dialog with specific choices.
Security options and warnings dialog.
Remove personal information on saving. Select this option to always remove user data from the file properties when saving the file. To manually remove personal information from specific documents, deselect this option and then use the Delete button under File > Properties > General.
Ctrl-click required to follow hyperlinks. In older versions of OOo, clicking on a hyperlink in a document opened the linked document. Now you can choose whether to keep this behavior (by unchecking this box). Many people find creation and editing of documents easier when accidental clicks on links do not activate the links.
The other options on this dialog should be self-explanatory.
Click the Macro Security button to open the Macro Security dialog (not shown here), where you can adjust the security level for executing macros and specify trusted sources.
File sharing options for this document
Select the Open this document in read-only mode option to restrict this document to be opened in read-only mode only. This option protects the document against accidental changes. It is still possible to edit a copy of the document and save that copy with the same name as the original.
Select the Record changes option to enable recording changes. This is the same as Edit - Changes – Record. To allow other users of this document to apply changes, but prevent them from disabling change recording, click the Protect buton and enter a password.
