Abstract

Techniques for rapid video on demand (VOD) media content breach response are described. In some embodiments, during content preparation, a server generates an encrypted media content item by generating a first encrypted portion using a first key derived from a first seed that is of a first type and generating a second encrypted portion using a second key derived from a second seed that is of a second type. In some embodiments, the server classifies the first portion in a first category (e.g., a prioritized category) and the second portion in a second category (e.g., a non-prioritized category). During a breach response, the server repairs the encrypted media content item by re-encrypting portions in the first category, e.g., re-encrypting the first encrypted portion using a replacement key derived from a replacement seed that is of the first type, and updating encryption metadata.
