Survey of Content Protection Technology

The types of content protection available today can be categorized into three groups.

Content protection can be imagined along two axes: the value of the content and the level of protection.

Thus, in increasing protection, the technology options for protecting your content with Ooyala are:

  1. Protected streams
  2. Playback authorization, including token-based authentication
  3. Digital Rights Management (DRM) systems

Protected streams

There are several technologies that secure the actual stream of data to your customers.

Streaming protocols in general have encryption or other protections designed into them. See the details in Protected Streams. To implement these protections, you do not need to do anything. Ooyala provides this protection.

Limits on concurrent streams are another form of stream-level protection. See more details in Limits on Concurrent Streams.

Playback Authorization

Playback authorization (a general term to cover various technologies) can be an additional security layer on top of protected streaming. Among these technologies are:

  1. Token-based authentication. Required for RTMPE and ensures that encrypted content cannot be downloaded until the client has been verified and prevents content from being played in a non-Ooyala player. There are several kinds of token-based systems:
  2. Distribution systems, like Widevine. See Widevine Modular Content Protection.
  3. Adobe Pass. See Integrating Adobe Pass with Ooyala Player.

Digital Rights Management (DRM) systems

Although there are many different DRM systems on the market, in general they all:

  • Provide the highest level of protection
  • Include sophisticated tamper-resistance
  • Can be circumvented only by highly-skilled hackers with custom tools

For more details on various options, see Digital Rights Management (DRM) Systems

Access Control

  • Publishing rules for restrictions on playback by geographic location, Internet domain, anonymous proxy controls, and more. Ooyala's publishing rules are detailed in Publishing Rules.
