DRM Combined Delivery and "Superdistribution"

NowSMS provides full support for OMA Digital Rights Management (DRM) v1.0, with support for forward lock, combined delivery and separate delivery.

"Forward Lock" is the most basic level of DRM. When "Forward Lock" is enabled, this indicates that the receiving device should not allow any non-text objects in the message to be forwarded off of the device. The device may allow the user to extract pictures, videos or sounds from the message and save them on the phone. However, any such objects remain forward locked, such that they cannot be forwarded to another user or transferred to another device

More advanced DRM restrictions can be applied to limit the number of times that the user can access an object, or start and end dates can be specified to limit how long the user can access an object. The restrictions can only be applied when using either "Combined Delivery" or "Separate Delivery".

"Combined Delivery" means that both the protected object and the rights object are delivered simultaneously. The protected object and its rights object are packaged as a multipart/related MIME object, which is usually retrieved by the receiving client via HTTP download or as part of the content of an MMS message.

"Separate Delivery" means that the protected object and the rights object are delivered separately. The protected object is retrieved by the receiving client via HTTP download or as part of the content of an MMS message. However, the protected object is locked and cannot be used until a rights object is separately delivered. In this case, the rights object is usually sent via WAP Push over SMS (sometimes premium rate SMS).

"Superdistribution" is a DRM method that allows the original recipient to redistribute an encrypted DRM content to other recipients. These new recipients have to come back to the original content provider in order to obtain rights to the object. "Superdistribution" is facilitated through "Separate Delivery".

You'll find more discussion of DRM and superdistribution in the following thread on the NowSMS discussion board.

Dear Bryce,

Since the release of Now SMS 2006, there has been a lot of activity on the NowSMS discussion board. We've highlighted some of the more interesting questions and discussions in this newsletter.

If you would like more information about upgrading to NowSMS 2006, please contact your Now Wireless sales representative, or e-mail nowsms

If you have any technical queries, please join us on the NowSMS Discussion Board.

  • 2-Way SMS and an XML-based Information Service
  • XML-based information services are quite common. When creating a 2-way SMS application, frequently this will involve extracting information from the received SMS and issuing an HTTP request to another server. That server might return a response in an XML format, which must be parsed in order to send an appropriate SMS response back to the original SMS sender.

    This thread on the discussion board takes a look at an SMS based horoscope service. An SMS message is received, which triggers a 2-way SMS HTTP script configured in NowSMS. This ASP script parses information from the received SMS, and issues an HTTP request to the horoscope service provider. The horoscope provider returns an XML response which is parsed by the 2-way script so that an SMS response can be sent back to the original message sender.

    A second example script shows how an MMS response could be sent back instead of SMS.

    Even if you're not interested in horoscopes, it makes for an interesting example of integrating 2-way SMS with an XML-based information service.

  • NowSMS and Bulk SMS
  • We frequently get questions about how to use NowSMS to support bulk SMS applications. It has often puzzled us why we get asked these questions, because we know that this is a common application.

    However, after a couple of questions on the NowSMS discussion board, it became somewhat obvious why we get these questions. The distribution list functionality in NowSMS is not very well documented.

    The following thread discusses options for creating and editing NowSMS distribution lists, explaining both the file based interface and the an HTTP-based interface that can be used to update distribution lists from a remote application server.

  • Provisioning OTA Bookmarks
  • For users, bookmarks are essential for navigating content on the mobile internet. Mobile internet users spend most of their time accessing sites that they have booked marked in their mobile devices.

    But how many mobile internet users actually know how to bookmark a site in their device. Sometimes a content provider just wants to be able to send a bookmark to the user so that they can more easily return to the content provider's site.

    Using the WAP OTA Bookmark function in NowSMS, you can send a bookmark to Nokia phones. However, the function is rarely supported by other manufacturers.

    The following thread provides an XML Settings document that can be used to send a bookmark to newer SonyEricsson devices (and hopefully other manufactuers will decide to also support this functionality in the future as it does use an OMA Provisioning Content standard).

  • SMS Command Line Interface
  • Sometimes the easiest way to integrate the ability to send an SMS alert into an application is via a command line interface.

    The following document contains a simple Windows script that can be used to facilitate a command line interface for sending SMS via NowSMS. This script allows recipient phone numbers, and the message text, to be specified on the command line.

    While the example script only supports sending text messages, it could be easily adapted to support sending other types of messages supported by NowSMS.
