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.
