In an example, an audio stream such as a voice call or live-streaming service may have mixed therein a user identification, which may identify the user as an authorized participant in the audio stream. For example, a user may identify himself to a smart phone, and then initiate a call with his bank. The smart phone may mix a user identification into the voice stream. A receiving device at the bank may demix the identification, and determine that the user is authorized to call about this account. In another example, identification may be used for DRM purposes, to identify a user as a legitimate participant in an audio stream. When a user is not authorized, an appropriate action may be taken, such as dropping the user, degrading the quality of the audio stream, or providing a notification that the user is not authorized. |
