Abstract
A system for and method of per access-point streaming media customization and privacy protected feedback in a wireless network. The system is operative to: encrypt real time streamed media content from a streaming media source; multicast the streamed encrypted media content for availability to a user device for playback, the user device sending out unicast responses at the time of joining or dropping the multicast; aggregate the unicast responses in the form of a connect multicast state or a disconnect multicast state of the user device based on the joining or dropping of the multicast; and provide information back to the streaming media source based on the aggregated unicast responses.
