Methods and systems for secure device action initiation using a remote device are described herein. The techniques described herein enable, among other actions, users to send a play chirp request to a lost or misplaced device, such as to one or both buds of a truly wireless earbud set. In the case of truly wireless earbuds, a shared secret known by both of the buds can be used to securely initiate the action over an unencrypted link (e.g., an unencrypted BLE link). This can be achieved by using the shared secret to sign an authentication challenge to prove that a remote device that also has access to the shared secret is authorized to initiate the action, thereby providing a secure process. In some implementations, the shared secret is an Identity Resolving Key (IRK), which may be randomly generated by the buds.

Secure device action initiation using a remote device

A system and method for securely verifying a connection between a remote device and an audio device. The method includes establishing a wireless connection between the remote device and the audio device. The remote device has an application configured to control operation of the audio device. An identity resolving key (IRK) for the application is obtained with the remote device. The IRK is transmitted to the audio device via the wireless connection. An instruction to is transmitted the audio device to generate a random resolvable address for the application using the IRK and to broadcast data containing the random resolvable address. The data containing the random resolvable address is received by the application of the remote device. An active audio connection between the remote device and the audio device is identified if the random resolvable address is able to be resolved by the application using the IRK.

Secure methods and systems for identifying bluetooth connected devices with installed application

A system and method for securely resolving an identity of an audio device. The method includes establishing a wireless connection between an audio device and a remote device. An identity resolving key (IRK) is received in an encrypted state from the audio device via the wireless connection. A data connection between the remote device and a server is established. The IRK is transmitted in the encrypted state to the server via the data connection. transmitting user credentials to the server via the data connection. The IRK is received in a decrypted state from the server via the data connection. An advertising packet broadcast from the audio device is received by the remote device. The advertising packet includes a random resolvable address for the audio device. The random resolvable address is attempted to be resolved using the IRK in the decrypted state to identify the audio device with remote device.
