    Abstract: A method for performing user authentication by a terminal is provided. The method includes receiving, by one secure application among at least one secure application installed in a secure area of the terminal, a user authentication request, identifying whether a valid user authentication result corresponding to the user authentication request exists, and in response to there being no valid user authentication result corresponding to the user authentication request, requesting a user authentication result from a user authentication module installed in the secure area, and providing, by the user authentication module, a user authentication result corresponding to the user authentication request to the secure application that has received the user authentication request or to the at least one secure application installed in the secure area of the terminal.

    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.

    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.
