1.2.1 Overview

This kit is an option to add the security function which is enabled by the license.
Characteristics:
- Since the security extension board and increasing memory are required, this kit is
installed by the service man.
- HDD data can be protected, and Job Log can be not displayed.
- Encryption processing is conducted by the encryption accelerator, so there is not much
influence on the machine performance.
- The security is secured since there is no method to take the key for encryption to the
outside of HDD.
- When the data needs to be deleted at the damage on the device, the user can regenerate
the encryption key, so that the data can be deleted easily.
For details of installation procedures, please refer to Installation procedure.
Protection of HDD data
Device's HDD records temporally image data like scanned images and PDL data, etc. at any
time. Also, the image data is always saved in the user box, FAX box, etc. If the user
information like the image data is stolen by extracting HDD, the original data can be
recovered easily by directly accessing and analyzing with Disk Editor, etc. For the security,
HDD encryption and full initialization of the HDD are used.
HDD encryption
Regarding the HDD dealing with images and PDL data, the information is written by
encrypting, and it is read by decoding. Therefore, information within the HDD is always
encrypted. Even when the HDD is stolen, recovering the data is too hard. For details,
refer to New Functions in the later chapter.
Full initialization of the HDD
When the data which is recorded temporality (e.g. images and PDL data) is not necessary,
0 data or random data is overwritten in the areas where the data exists. By doing so,
recovering the original data is too hard. For details, refer to New Functions in the later
chapter.
