Abstract

Techniques and a system are provided for protecting content (or media item) streamed over a network from unauthorized access. As an example, the streaming protection system generates statistics when a client requests a media item. The statistic may be generated based on various factors. The media item is divided into different portions, each portion requiring a different key to decrypt the portion so that it may be viewed by a user. Based on the generated statistic, the streaming protection system determines whether or not to allow the client access to the decryption key for a portion of the media item.
