Temporary Unlock Fingerprint for Display Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when lending their personal display devices to others, as existing methods require unlocking or sharing lock codes, leading to security concerns and inefficiencies, especially when temporary access is needed.
Innovation Solution
A display device and method that allows setting and releasing a temporary unlock mode using a fingerprint, enabling convenient temporary access while maintaining security through a fingerprint recognition system integrated with the display unit, with features like valid time limits and unlock attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock function is set to maintain security, then security is improved, but ease of operation deteriorates when lending the device to others
Solution Approach 1:
The patent segments the unlock function into multiple types: permanent unlock fingerprints and temporary unlock fingerprints. This segmentation allows the device to maintain security through permanent unlock protection while enabling convenient temporary access for others through temporary unlock fingerprints, resolving the contradiction between security and ease of operation when lending the device.
Solution Approach 2:
The patent introduces dynamic characteristics to the unlock system by implementing temporary unlock fingerprints that have validity periods and can be activated or deactivated. This dynamic approach allows the system to adapt between secure locked state and accessible unlocked state based on temporary needs, resolving the contradiction between maintaining security and enabling ease of operation.
2Ease of operation
If a guest unlock mode is implemented to allow temporary access, then ease of operation is improved, but adaptability deteriorates because only some functions are permitted
Solution Approach 1:
The patent implements temporary unlock fingerprints that provide universal access to all device functions, not just limited guest mode functions. When a temporary unlock fingerprint is activated, it enables complete device functionality including camera, messaging, and other applications, resolving the contradiction between ease of operation and adaptability by making the temporary unlock mode as versatile as the permanent unlock mode.

AI summary
A display device and a method for controlling the same are disclosed. The display device comprises an input unit configured to receive a command for generating an event and a fingerprint; a control unit configured to generate the event in accordance with the command and process the generated event; and a display unit configured to display a user menu, wherein the input unit includes a touch recognition layer for recognizing a touch input and a fingerprint recognition layer for recognizing a fingerprint, the touch recognition layer and the fingerprint recognition layer being formed in a single body with the display unit and receiving a command for generating an event of a temporary unlock fingerprint setting mode and a first fingerprint different from a registered fingerprint, the control unit implements the temporary unlock fingerprint setting mode in accordance with the command for generating the input event, sets the input first fingerprint to a temporary unlock fingerprint, and unlocks the display device if the temporary unlock fingerprint is input thereto, and the temporary unlock fingerprint is released in accordance with a predetermined condition.
