Abstract: Devices, methods, and non-transitory program storage devices are disclosed to enable the automatic establishment of a secure audio/video data streaming connection between electronic devices. For example, a first electronic device may enter into a first state of a peer device advertising protocol, and then, based on a determination that the first electronic device meets a first set of device state criteria (e.g., including at least an orientation state criterion), the first electronic device may enter into a second (e.g., enhanced) state of the peer device advertising protocol. In response to detecting a presence of a second electronic device in its proximity, the first electronic device may connect to the second electronic device via a secure peer-to-peer connection protocol and then send one or more images captured by a first image capture device of the first electronic device to the connected second electronic device via the secure wireless peer-to-peer connection protocol.

Abstract: Aspects of the subject technology include receiving, by a first device, a voucher data item, from a second device, providing, by the first device, an invitation to at least a third device to join a group communication session with at least the first device, and providing, by the first device, the voucher data item to at least the third device to verify that the first device is vouched for by the second device for participation in the group communication session initiated by the first device. The voucher data item may include participant information associated with the second device. The voucher data item may also be signed with a key associated with the second device.

Abstract: Techniques for monitoring an audio stream for triggering events are disclosed, where the triggering events may include a particular sound identified in the audio stream. In addition, the techniques include detecting the particular sound in the audio stream and/or providing an event notification to a user device via a network connection. A user device can request permission to initiate a two-way audio stream between the computing device and the user device. Further, the techniques may include receiving an indication to initiate the two-way audio stream with the user device. In addition, the techniques may include providing an alert that permission has been granted to initiate the two-way audio stream. Also, the device may include initiating the two-way audio stream with the user device.

Abstract: Aspects of the subject technology include transmitting, by a first device, an advertisement message corresponding to a communications session the first device is participating in with at least a second device. The first device may receive, during the communications session, a communications session control message generated by a third device. The communications session control message may include information contained in the advertisement message. The first device may validate the third device based on the communications session control message and remove the first device from the communications session in response to successfully validating the third device.
