 When you set an open document password, you will be
prompted to enter that password when opening the PDF output.
 When you set a permissions password, you will only be able to
perform the actions specified in the security settings. If you do
want to change these settings, you must enter the permissions
password.
The Readiris security settings are similar to the standard protection
features offered by Adobe Acrobat.
Note, however, that in Readiris the open document password and
permissions password must be different.
If a PDF document is protected with both types of passwords, either
password can be used to open the document.
R EPURPOSING PDF DOCUMENTS
Next to generating PDF documents, Readiris can also repurpose
PDF files: Readiris converts image PDFs into text PDFs or any
other supported text format and unlocks read-only PDF content.
