Preventing Data Leaks Due to Unauthorized Transmission

You can specify in the Address Book which users are allowed to send files using the scanner function.

You can also limit the direct entry of destinations to prevent files from being sent to destinations not

registered in the Address Book. For details about preventing data leaks due to unauthorized

transmission, see "Preventing Data Leaks Due to Unauthorized Transmission".

Using S/MIME to Protect E-mail Transmission

When sending mail from the scanner to a user registered in the Address Book, you can use S/MIME

to protect its contents from interception and alteration, and attach an electronic signature to guarantee

the sender's identity. For details about using S/MIME to protect e-mail transmission, see "Using S/

MIME to Protect Email Transmission".

Protecting Registered Information in the Address Book

You can specify who is allowed to access the data in the address book. You can prevent the data in

the address book being used by unregistered users.

To protect the data from unauthorized reading, you can also encrypt the data in the address book.

For details about protecting registered information in the address book, see "Protecting the Address

Book".

Overwriting the Data on the Hard Disk

To prevent data leaks, you can set the machine to automatically overwrite temporary data. We

recommend that before disposing of the machine, you overwrite all the data on the hard disk.

To overwrite the hard disk data, the optional DataOverwriteSecurity Unit is required. For details about

overwriting the data on the hard disk, see "Deleting Data on the Hard Disk".
