Display Apparatus Automatic User Authentication via Facial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication methods for shared display devices, such as TVs, require users to repeatedly input passwords, causing inconvenience.
Innovation Solution
A display apparatus and method that automatically authenticates users by photographing and recognizing users using image information, associating recognition information with screen states, and comparing it to determine whether to display customized content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password input method is used for user authentication, then user identity can be verified, but user convenience deteriorates due to repeated password entry
Solution Approach 1:
The patent replaces the mechanical password input system with an optical recognition system. A camera captures user facial images, and image processing algorithms automatically verify user identity without requiring manual password entry. This substitution eliminates the need for users to remember and repeatedly input passwords while maintaining authentication reliability through biometric recognition.
Solution Approach 2:
The system enables self-service authentication where the user's facial features serve as the authentication credential. The display apparatus automatically captures, processes, and verifies the user's facial image without requiring active participation beyond presenting their face. This self-service mechanism improves convenience while maintaining security through automatic biometric verification.
2Ease of operation
If automatic face recognition is implemented, then user convenience is improved by eliminating password entry, but system complexity increases due to additional hardware and processing requirements
Solution Approach 1:
The patent makes the display apparatus multi-functional by integrating face recognition capabilities into the existing display system. The camera and processing units serve dual purposes: they can capture images for authentication and also function as part of the display's multimedia capabilities. This universality approach adds authentication functionality without requiring completely separate dedicated hardware systems, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The patent merges the face recognition system with the display apparatus by integrating the camera, processing unit, and authentication logic into the existing display structure. Rather than creating a separate authentication device, the system combines multiple functions (display, camera capture, image processing, and authentication) into a single integrated unit, reducing the number of separate components and simplifying the overall system architecture.

AI summary
A method for displaying of a display apparatus is provided. The display method includes in response to a first command being input, photographing a user and generating first recognition information; associating the first recognition information with information on a screen displayed when the first command is input and storing the associated information in the display apparatus; in response to a second command being input, photographing a user and generating second recognition information; and comparing the first recognition information and the second recognition information and determining whether to display content based on a result of the comparison.
