Encrypted recording
Call Recorders feature a system for encrypted recording whereby IC
cards called CryptoCards are used as a key. Encrypted recordings are
made to prevent unauthorized playback of and listening to recordings.
The system is very safe and recommended when some sort of security
breach is possible. Examples of such a situation are:
•
The Call Recorder is connected to a network or even internet and
there are reasons to think that password security is not enough.
•
The Call Recorder can be accessed and operated by persons who
are not allowed to listen to all recordings and there are reasons
to think that password security is not enough.
•
Privacy is considered to be an issue and therefore strict
procedures must be maintained around listening to the
recordings.
The CryptoCard is a chip card that holds the key to the encryption and
decryption. Encrypted recordings can only be played back together with
the original or a matching CryptoCard and its password.
The 19” model has an internal reader and the case must be opened to
place the card. The idea behind this is that a recorder built into a 19”
rack normally will be accessed from remote only. It is a drawback rather
then an advantage when the card can easily be removed. The Privacy
Card is recommended which means that recordings can only be
reproduced on a PC with the matching CryptoCard.
CryptoCards can be obtained from your Vidicode products supplier. The
use of the CryptoCard encryption function is enabled in the Recorder
settings menu. See § 4.2 to enable the use of a CryptoCard.
8.1
Several types of CryptoCard
As mentioned there are cards that can be used for recording and for
playback and there are cards that can be used for recording only, the so
called “Privacy Cards”. It is important to understand the difference.
•
When it is important to be able to listen to recordings on the Call
Recorder, use the standard CryptoCard.
•
When you prefer that it is not possible to listen to recordings on
the Call Recorder, use the CryptoCard Privacy card.
It is also possible to supply sets of individual cards with a “Master Card”
that can be used to decode all the individual cards. The application is
when employees are only allowed to listen to their own recordings
while, when needed, the management must have the ability to listen to
all recordings.
