Disclosed are various embodiments relating to a security framework for media playback. In one embodiment, a client device has a decryption module, a streaming module, and a playback module. The playback module may be configured to request media data from the streaming module and render the media data on an output device. The streaming module may be configured to obtain the media data from the decryption module by a request that specifies a size of the media data. The size may be dynamically determined based at least in part on an amount of available temporary data storage. The decryption module may be configured to decrypt a portion of an encrypted media file based at least in part on the specified size to produce the media data.

Security framework for media playback

Disclosed are various examples for securing the transmission of files to and from a client device. In some examples, an initialization token is identified for a file that includes a number of portions. An algorithm is iteratively applied to the initialization token to determine that no repeated output occurs over a number of iterations corresponding to the number of file portions. Initialization data is transmitted from a client device to a management service that manages access to the file. The initialization token is included in the initialization data if no repeated output occurs when the algorithm is iteratively applied over the number of iterations.

System and method to secure the transmission of files to a valid client

Disclosed are various examples for securing the streaming of a media file from a web service to a media player. A request for a portion of a media file can be received including an authentication key. A web service can validate the authentication key. If the authentication key validates, the web service can send the portion of media to a media player. The media player can render the media on a display of a client device. Requests can be iteratively sent for each portion of the media file.
