Abstract: A client system comprises processing circuitry configured to receive, from a user device, a first access request comprising a first instruction to access a protected resource; transmit a token request for an access token to be used for accessing the protected resource; and receive an access token in response to the token request, the access token having a corresponding time to expire. The client system comprises a token storage unit configured to store the access token. The processing circuitry is further configured to receive a rejection message indicating that the access token is not valid for receiving the protected resource; and store, at the token storage unit, an invalidation flag associated with the stored access token, in response to receiving the rejection message.

Abstract: Dynamic device speaker tuning for echo control includes detecting audio rendering from a speaker on a device; based at least on detecting the audio rendering, capturing, with a microphone on the device, an echo of the rendered audio; performing a Fourier Transform on the echo and the rendered audio; determining a real-time transfer function for at least one signature band; determining a difference between the real-time transfer function and a reference transfer function; and tuning the speaker for audio rendering, based at least on the difference between the real-time transfer function and the reference transfer function, by adjusting an audio amplifier equalization. For some examples, the signature band represents a wall echo or an alternative mounting option. For some examples, the echo is collected during intervals while the audio rendering is ongoing.

Abstract: A computer-implemented method for managing a secure data item that is jointly accessible by the first user and the second user. In the method a first system receives a data request comprising an instruction to transmit the secure data item to a second system. The first system identifies that the secure data item is jointly accessible by the first user and the second user, and in response transmits an authorisation request to the second user device. The authorisation request comprises a prompt for the second user to authorise the data request. The first system receives a grant message indicative of the second user granting the authorisation request and in response transmits the secure data item to the second system. The secure data item is prevented from being sent to the second system, if the grant message is not received.
