FlexiPDF has a number of different security features for your documents.
For example, you can insert a copy of your handwritten signature as described in Signatures. This looks nice, but it provides no real protection.
The following methods are more suitable and will be explained in the next sections:
▪Document security
| You can use these security settings to restrict what other users can do with your PDF. For example, you can prevent editing or printing of your PDF with a simple password. |
| However, people may still manage to bypass this type of protection if they know how to do it. |
▪Digital signatures
| You can digitally sign your PDF file. Anyone who receives a signed PDF can easily recognize if it has been modified since it was originally signed. This form of guarantee is difficult to outwit and is normally used for legal documents. |
▪User restrictions
| You can set up user restrictions for your PDF file and thus limit any editing of the document to the actions that you specify. |
