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.
