A system receives an audio-video recording that includes image frames. For each image frame, a portion of the image frame is identified that corresponds to a first face of a first subject. An image region is determined for the identified portion of the image frame. A first face portion of the audio-video recording is stored that corresponds to the determined image region for each of the image frames along with a private key for the audio-video recording and a first mask identifier for the first subject. A public key is generated for the private key. A remaining portion of the audio-video recording is associated with the generated public key and the first mask identifier for the first subject. The remaining portion, the public key, and the first mask identifier are provided to a media server that communicates with a media player.
