Abstract: A computer-implemented method of controlling a computing hardware accelerator in a movable camera comprises: acquiring images from the movable camera; obtaining an indication of a physical state of the movable camera, indicating whether the movable camera is in a moving state or in a still state; and allocating exclusive access to the computing hardware accelerator based on the indication of the physical state. The disclosure further relates to a camera system for carrying out the computer-implemented method of controlling a computing hardware accelerator in a movable camera.

Abstract: Upon detecting an event indicating enabling of security sensitive functionality of an electronic device, a value previously unknown to the electronic device is obtained and the current content of the data storage to a new current content of the data storage is updated according to an updating function based on the current content of the data storage and the value, wherein, without privileged access, the current content of the data storage can only be updated using the updating function. The value is further obtained in a management module and an expected new current content of the data storage is determined in the management module according to the updating function based on known original content of the data storage and the value. Upon determining that the new current content of the data storage differs from the expected new current content of the data storage, a validation module generates a security notification.
