PDF Encryption when using DSS OCR
DSS provides an OCR engine which is capable of producing many output file formats. Included in these
formats are Searchable PDF and Searchable PDF/A. When the output file type is one of these PDF types,
PDF encryption may be applied. When DSS OCR creates the files the PDF encryption used is PDF 1.7
Extension Level 3 for AES encryption using 256-bit keys. Keys are generated from user-entered
passwords.
When the system is configured to produce non-searchable PDF or PDF/A output files the encryption is
done on the device itself before the file is sent to DSS. For this scenario please see the documentation
for the device being used to determine the PDF encryption algorithm.
On some devices, such as MFP Flow devices, there is an OCR engine built into the device firmware itself.
The internal OCR engine is used when the device is configured to send job directly from the device, the
DSS OCR engine is used when the device is configured to send jobs via DSS. If the internal OCR engine is
used then the device firmware applies PDF encryption. For this scenario please see the documentation
for the device being used to determine the PDF encryption algorithm.
