Hi,

I am about to develop an application that should implement some DRM solution to protect its data files (proprietary content).  Do one of you already used forward-lock on NS60 1.x platform ?

Is there some  impacts on file access ? specific APIs to use ?

Thanks,
Eric

Hi,

I'm not 100% sure about this, but for now, I think OMA DRM applies only to OTA data that is DRM-protected. For example, you may have an OTA operator logo with forward-lock on in which case the platform will take care of it and make sure the lock is applied.

Hence currently there is no programmatic access to DRM because it's restricted to OTA content. I suppose this will change in the near future with many parties being involved in this area.

Comments are welcome Smiley

Cheers,
Pawel

That was also my understanding Cry
But my datafiles will be downloaded. They only have a specific MIME type.

His this issue been solved? It's a pretty old topic.

Anyway, what you need to know about DRM is that two objects are being involved in DRM protection: content object (CO) and rights object (RO). Although I have not impemlemented any DRM solution, I don't think that it's enough only to set the MIME-type of a file to be downloaded. DRM agents work so that they look for ROs when access to a certain CO is being requested. If the DRM agent is unable to find the RO, then it will refuse access to the CO.

These are for Symbian 8.0
Unfortunately I never had time to test them.  Sad
