Video and audio streams have to be played by standard PC / MAC players and for this reason can’t be encrypted. But, there are several levels of event access restriction that can be applied to make your event more secure:
the simplest and lowest level of security is to apply a common password protection to your event. This is done via the Visual Webcaster platform, and can be applied and removed by either BT or you
One level higher is our unique username / password security. Each participant is issued a unique username and password which is a one-time use access code. It will authenticate the PC first used for that event, and won’t work again on any other machine. Usernames and passwords can be provided by BT or you
a very popular technique for access restriction is to validate the participant’s IP address against a list of pre-authorised addresses. We can also offer URL referral authentication, whereby you place a hyperlink to your event on an internal, access restricted page (on an intranet or similar access). Only participants clicking on the hyperlink on that page can access to your event.
finally, you can utilise internal multicasting or unicasting behind the firewall. This makes sure that only users within that network can access the streams.
