The Trusted Transaction Server (TTS)™
Marries Electronic Media Distribution and Copyright Security

TTS organizes a commerce environment in which security and copyright protection are maintained at every step in the process and at every lifecycle stage of the content – even if it is captured at the sound card or through analogue pick-up.

Here we describe the typical deployment scenario as played out by the consumer, the working server and, finally, the copyright holder.

1. Consumer signs up
Customers come to the server and set up their accounts, receiving a decryption key that their media players use to decrypt the Download Packages (DLP) that house the content they purchase.

2. Consumer chooses tracks
The consumers select the content of their choice and transfer it into their players, depending on the commerce software mediating the payment, shipping and receipting systems.

3. TTS embeds Robust Open Watermark
The Robust Open Watermark (ROW) is fixed to the content to identify it as originating in a secure environment before being made available on the server.

4. TTS affixes SecureChannel Watermark
Technically an attachment, the SecureChannel provides a vehicle for value-added data like CD liner notes. The SecureChannel data is only available to the authorized consumer with the corresponding account key.

5. TTS embeds Forensic Watermark
The moment before the media is shipped, the transactional data is recorded and embedded into the content, making the transaction fully traceable to an individual account.

6. TTS wraps & ships track
The content is encrypted with a private key on the server that corresponds to the account key in the player that can decrypt the media for immediate play.

7. Forensic Analysis
In the event that the content is found outside the secure domain (i.e. on an FTP server), content owners have the ability to decode the forensic watermark and trace the transaction.

With the TTS, even the most demanding media distribution models are facile operations.
