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.

Abstract: The invention relates to a method for adjusting a digital camera. The invention also relates to a corresponding device and a corresponding computer program. An original image recorded by the camera is received. The original image has an original aspect ratio. A first user input defining a center point of an area of interest within the original image is received. A second user input defining a perimeter for the area of interest of the original image is received. The perimeter for the area of interest has the same aspect ratio as the original aspect ratio. The camera view is adjusted based on the first user input and the second user input to provide a zoomed image of the defined area of interest. The zoomed image is centered on the center point defined by the first user input. Finally, the zoomed image is displayed to the user on a display screen.
Abstract translation: 本发明涉及一种用于调整数码相机的方法。 本发明还涉及相应的设备和相应的计算机程序。 接收由相机记录的原始图像。 原始图像具有原始宽高比。 接收定义原始图像内的感兴趣区域的中心点的第一用户输入。 接收定义原始图像的感兴趣区域的周长的第二用户输入。 感兴趣区域的周长与原始宽高比具有相同的纵横比。 基于第一用户输入和第二用户输入来调整相机视图以提供所定义的感兴趣区域的缩放图像。 缩放图像以第一个用户输入定义的中心点为中心。 最后，在显示屏幕上向用户显示缩放图像。
