PrivateWave
Quick Start Guide for BlackBerry OS

This guide provides you easy step-by-step instructions to help you get started with  PrivateWave .

Secure calls with  PrivateWave

Calling with  PrivateWave  is a very easy task. You can both use your contact list or directly dial a number using the dialpad.

 

To make a secure call, you and the called party must have PrivateWave software running on the mobile device, be connected to the Internet and to the same PrivateServer .

Calling by contact list

figure 2. you address book is shared with the application

As you can see in figure 2. you address book is shared with the application each contact can show a coloured ball at its left, or nothing at all. These are status marker and they represent the Presence Status for each contact.

Presence

The Presence avoid users to call contacts who are not reachable, eg: because they do not have  PrivateWave  activated and/or connected. The main value of this feature is to improve user experience suggesting the possible outcome of a call.

Contacts lists

PrivateWave  gives you access to three different kind of lists:

• ALL: it lists all the contacts which are in the mobile address book, ordering them in the very same way.
• KNOWN: it shows only known contacts (registered or not) according to  PrivateServer 's knowledge. This means it is a list of the contacts that are recognised by the server and thus can have a status.
• FAVOURITES: it reads the contacts marked by you as " PrivateWave  favorites". It's a selection of contacts you choose to have apart, in order to make speed calls.

Each list may show a Contact status beside each contact. The contact status legenda is shown below:

Contact status

	Online	The contact is reachable. You can make a secure call to the user.
	Offline	The contact is not reachable, because is not under network coverage or is offline. You can try to make a secure call but the call will likely fail
	Error	There is a comunication error between your phone and the server. The contact status is unknown, anyway you can try to make a secure call

 

Calling by keyboard

You can make a secure call to any arbitrary number (presuming that the call peer has  PrivateWave  connected) by simply entering the number on  PrivateWave  main menu and pressing the dial button.

Receiving a secure call with  PrivateWave

 Once  PrivateWave  is installed and all the settings are correctly configured on your device, you are able to receive a secure call.  PrivateWave  displays a screen when an incoming secure call is arrives to your phone. Press the Accept (green) button to allow the connection. After the system have exchanged and verified the security keys the you can start the conversation.

Checking your security

A  PrivateWave  phone call is always encrypted. To check that nobody is intercepting the call, you must verify the security verification words with you remote party. After the call has been connected  PrivateWave  displays the same two security verification words at the bottom of the screen to both parties. If both of you and your contact see the same security verification words then the call is secure. The security verification words are different each time you make or receive a secure call. If the words are not the same hang up the call immediately as this may be a sign of a security attack.

Secure Messages

You can communicate with your peers by text messages using the Secure Messages System which provides Secure Messages. A Secure Message is a text message that travels into the same encrypted architecture of the Secure Call. 

Secure Messages rely on the very same security infrastructure the voice calls do. Plus for security each Secure Message is blanked 15 minutes after it's been read or sent.
