Abstract: There are provided a storage device and an operating method thereof. The storage device includes: a nonvolatile memory device including a system block for storing firmware data including a program code of firmware, a signature in which the program code is encoded, and an authentication key; a volatile memory device configured to store operational firmware data; and a memory controller configured to, when power is applied to the storage device, store the firmware data as the operational firmware data in the volatile memory device, perform a firmware validity test for detecting whether the operational firmware data and the firmware data matches each other, in response to a test event, and perform a reset operation based on a result of the firmware validity test.

Abstract: The present invention relates to a mobile terminal and a control method therefor and, more specifically, to a method for configuring a security section of video content when a mobile terminal senses an input signal corresponding to registered fingerprint information. In order to achieve the aforementioned objective or another objective, the mobile terminal according to one aspect of the present invention comprises: a display unit; a memory; a sensing unit for sensing a fingerprint input; and a control unit, wherein the control unit senses a first input signal when first video content is outputted, extracts the first fingerprint information from the first input signal, and configures the security section of the first video content when the first fingerprint information corresponds to the registered fingerprint information, and the security section is a section in which at least a part of the first video content is encrypted on the basis of the time at which the sensing of the first input signal is maintained.
