Biometric Authentication Integration in Image Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display devices face security vulnerabilities during user authentication, particularly when relying on password or PIN inputs, and biometric authentication using external devices complicates the user experience.
Innovation Solution
Integrating a control device capable of biometric authentication within the image display device to perform authentication, allowing for secure operations without additional user procedures and maintaining usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is performed using an external device, then security is strengthened, but device complexity and usability deteriorate due to additional authentication procedures
Solution Approach 1:
The patent merges the biometric authentication function into the image display device itself by integrating a biometric authentication unit that can directly perform authentication without requiring external devices. This integration eliminates the need for separate authentication procedures and reduces overall system complexity while maintaining strong security through built-in biometric capabilities
2Ease of operation
If password or PIN authentication is used, then ease of operation is maintained, but security becomes vulnerable
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system that uses physiological characteristics such as fingerprints, facial recognition, or iris patterns. This substitution maintains user convenience while significantly enhancing security, as biometric features are inherently more difficult to compromise compared to passwords or PINs

AI summary
Provided is an image display device including: a communication unit configured to receive, from a control device, a control command for controlling an operation of the image display device; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, wherein the processor is configured to execute the one or more instructions to: receive first user information about a first user corresponding to a user of the control device and authentication state information representing a user authentication state in the control device; when the control command includes an operation request that requires authentication, perform the authentication based on the first user information, the authentication state information, and second user information about a second user corresponding to a user of the image display device; and perform the operation in response to the control command.
