Abstract: An apparatus and a method with image recognition-based security are disclosed. The method includes, for an unlocked terminal, tracking a face detected in a previous frame, detecting a background region change between the previous frame and a current frame based on a region of the tracked face, when the background region change is not detected, determining whether a state maintenance time fails to meet a preset time, in response to the state maintenance time failing to meet the preset time, determining an operation mode to be a first operation mode for determining whether recognition succeeds for the current frame, performing the first operation mode, including performing face detection with respect to the current frame, and maintaining the unlocked state of the terminal for the current frame when the face is detected as a result of the performing of the face detection, representing that the recognition succeeded for the current frame.

Abstract: A method and a closed-loop antenna impedance tuning (CL-AIT) system are provided. An input reflection coefficient is determined. The input reflection coefficient and a threshold value are compared to determine whether the input reflection coefficient is greater than the threshold value. In response to determining that the input reflection coefficient is greater than the threshold value, an optimal tuner code is determined based on a tuner code search algorithm. The optimal tuner code is applied to configure the CL-AIT system.

Abstract: According to an embodiment, a method in a closed-loop antenna impedance tuning (CL-AIT) system is provided. The method includes determining whether a transmitted power is above a pre-determined threshold, when the transmitted power is above the pre-determined threshold, determining a bypass input reflection coefficient, determining whether the bypass input reflection coefficient is greater than a bypass threshold, and when the bypass input reflection coefficient is greater than the bypass threshold, determining an optimal tuner code based on a tuner code search algorithm.

Abstract: An electronic device is provided. The electronic device includes a memory and a processor, the processor allocates first and second address spaces (AS) to the memory in rich execution environment (REE) when detecting a request to write data, writes the data to the first AS and detect access to the second address space in the REE, configures access permission of a first user virtual memory AS (VMAS), mapped to the first address space, in the REE so that write access is deactivated by a trusted environment manager when detecting access to the second AS, configures access permission of a second user VMAS, mapped to the second AS, in the REE so that read access is activated and write access is deactivated, and configures access permission of a first kernel VMAS, mapped to the first AS, in the REE so that write access is deactivated by the trusted environment manager.
