E-Shredding
E-shredding presentation
Introduction
The e-shredding feature is a security feature which allows to overwrite any user data (print/copy/
scan) when it is deleted from the system.
This feature prevents the recovery of any deleted user data (files' content and attributes)
A deleted job is a job that cannot be retrieved from any user interface.
When is a job deleted?
A job is deleted either:
• When it is manually deleted from a Smart Inbox
• After it was successfully printed and was not saved in a Smart Inbox ('Save printed jobs in a
Smart Inbox' system setting is disabled in the Océ Express Webtools)
• After a 'ScanToFile to remote destination' has been successfully performed
• After a 'ScanToFile to USB stick' has been performed successfully or not (only on Océ
PlotWave 300/350 and Océ ColorWave 300)
• When it is automatically deleted after a timeout:
- When the end of the job lifetime in the Smart Inbox is reached ('Save printed jobs in a Smart
Inbox' system setting is enabled in the Océ Express Webtools and the 'Printed jobs in Smart
Inbox: job lifetime' is set)
- When the time for the cleanup of the 'Scans in Smart Inbox' is reached
• When a 'Clear system Remove all jobs' is performed on the printer local interface
E-shredding algorithms
Select one of the three e-shredding behaviours:
•
DOD 5220.22-M: 3-pass overwriting algorithm (compliant with the US Department of Defense
directive):
•
Gutmann: 35-pass overwriting algorithm with random data
•
Custom: set the number of passes, from 1 to 35.
NOTE
The e-shredding feature has been designed to minimise impact of the global system
performance.
However the more passes selected, the more impact it has on general performance.
It is recommended to minimise the number of passes when document production is required.
Enable the e-shredding
Before you begin
You must be logged as a System Administrator or a Power user.
NOTE
When you enable the e-shredding, the system automatically disables the 'Save printed jobs in a
Smart Inbox' setting. The jobs previously printed and stored in the Smart Inbox are deleted.
They are not e-shredded.
