Abstract: An apparatus comprises memory storage circuitry comprising a plurality of memory storage locations to store data; an interface to receive an address from a requester; decryption circuitry to obtain a decrypted address by decrypting, based on a decryption key, an address received from the requester; and access control circuitry to select, based on the decrypted address obtained by the decryption circuitry, a memory storage location of the memory storage circuitry to be accessed.

Abstract: Aspects of the present disclosure relate to an apparatus comprising TEE circuitry configured to maintain a list of trusted devices, and interface circuitry to provide communication between the TEE of the apparatus and TEE circuitry of a device communicatively coupled to the apparatus. The TEE circuitry of the apparatus is configured to perform, with the TEE circuitry of the device, a remote attestation in respect of the TEE circuitry of the device. Responsive to a positive outcome of the remote attestation, the device is added to the list of trusted devices. The TEE of the apparatus receives, from the TEE circuitry of the device, an indication of one or more further devices which are trusted by the device, and adds said one or more further devices to the list of trusted devices.

Abstract: A computer-implemented method of operating a device is provided. The method comprises operating a sensor to capture a data input, individuating an element of the data input, tagging an individuated element with metadata, matching the metadata with an associated permission set, and applying a restricting function defined in the associated permission set to the individuated element during a process flow to produce augmented reality output data restricted as required by the associated permission set. A device is also provided, comprising a sensor, an individuating component to individuate an element of sensor data from the sensor, a tagging component to tag the individuated element, a matching component to match a tag of the individuated element with a permission of a permission set, and a restricting function component to restrict an application's interaction with the individuated element.
