Mobile Terminal Fingerprint Video Security Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to securely configure and play video content on mobile terminals by setting up a security section using fingerprint recognition, ensuring that only authorized users can access specific portions of the video.
Innovation Solution
A mobile terminal with a display unit, memory, and a controller that senses input signals to extract fingerprint information and set up a security section in video content, allowing encryption of portions based on time, and displaying security indicators when the security section is active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint recognition is implemented for video security, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent embeds the fingerprint sensing unit within the display unit structure, integrating biometric authentication capability into the existing display component. This nesting approach adds security functionality without requiring a separate dedicated security hardware module, thereby improving video security while minimizing the increase in device complexity
Solution Approach 2:
The controller is designed to handle multiple functions: it controls both the display unit and the fingerprint sensing unit, and manages video playback with security section setup. By making the controller universal and multi-functional, the patent avoids adding separate dedicated controllers for fingerprint recognition and video management, thus improving security reliability while keeping device complexity manageable
2Reliability
If security section is set up during video playback, then security functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The patent sets up the security section during video playback by detecting fingerprint input, which is a preliminary action that establishes security parameters before full security enforcement begins. This allows the system to prepare security configurations dynamically during playback without requiring pre-planning, improving security functionality while maintaining ease of operation through automatic detection and setup
Solution Approach 2:
The system automatically detects fingerprint input signals and autonomously sets up security sections without requiring manual configuration by the user. The controller self-manages the security setup process by detecting the fingerprint event and automatically configuring the security parameters, thereby improving security functionality while eliminating complex manual operations

AI summary
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.
