The Barix system
The Barix Streaming Client encrypted file playback system has two parts:
- a server side file encryption component
- a client side decryption module
First, an organisation must generate a random key, to be used to encrypt and decrypt the files; a method is suggested in the download software given by Barix, or sites such as GRC[1] can be used.
This key must be loaded into the Exstreamer, to enable it to decrypt encrypted files. Where a retailer is ordering significant quantities of Exstreamers, this step can be incorporated into the product build process by Barix, otherwise it must be manually loaded into the device; instructions are given with the software pack from Barix.
On the server side, files are encrypted using the secret key, then stored onto USB; the USB is then sent to the remote location (shop, hotel, bar...), where staff plug it in to the Exstreamer. The same files can be loaded on many USB sticks and sent to multiple locations (if, for example, an organisation wishes to operate with a single key for all locations, to simplify the logistics of sending files around), or a key per location can be used.
Encrypted files cannot be played on a standard player, or even on an Exstreamer if it does not have the correct firmware and the matching password that the files were encrypted with.
