Marker-Based Authentication for Intuitive Device Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for establishing a communication connection between electronic apparatuses and user terminals are not intuitive and require additional user input, lacking simplicity and ease of use.
Innovation Solution
An electronic apparatus and user terminal system that displays a marker, including text or images, to guide user operation for establishing a connection, with the user terminal authenticating the apparatus by capturing an image and transmitting a confirmation signal to establish a communication connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods (ultrasonic wave or pin code) are used to establish communication connection, then connection reliability is ensured, but user operation complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent replaces manual input methods (mechanical keyboard input, button pressing) with optical recognition technology. The user terminal captures an image of the marker displayed on the electronic apparatus, and the system automatically extracts connection information from the marker pattern, substituting mechanical user operations with optical field-based automatic recognition.
Solution Approach 2:
The system enables self-service connection establishment where the user terminal automatically captures the marker image, extracts connection information, and initiates connection without requiring manual intervention. The electronic apparatus also automatically displays the marker and processes connection requests, reducing the need for user input while maintaining connection reliability through automated authentication.
2Reliability
If additional user input is required for connection establishment, then connection security is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent introduces a marker as an intermediary element that carries connection information in a visually encoded format. Instead of direct communication between devices requiring manual authentication, the marker serves as a mediator that the user terminal captures and processes automatically, simplifying the interaction while maintaining security through the encoded information in the marker pattern.
3Reliability
If manual authentication methods are used, then connection security is maintained, but user experience and ease of operation deteriorate
Solution Approach 1:
The patent replaces manual authentication input (typing PIN codes, pressing buttons) with optical image capture and automatic processing. The user terminal uses its camera to capture the marker image, and the system automatically extracts and verifies the connection information, substituting mechanical authentication steps with optical recognition and automated processing.
Solution Approach 2:
The electronic apparatus pre-generates and displays the marker containing encoded connection information before the connection process begins. This preliminary action prepares the authentication data in advance in a machine-readable visual format, allowing the user terminal to automatically capture and process it without requiring real-time manual input during the authentication phase.

AI summary
An electronic apparatus includes a display, a communication interface, a memory comprising at least one instruction, and a processor configured to execute the at least one instruction, and the processor, by executing the at least one instruction, is configured to, based on an external user terminal being discovered through the communication interface, control the display to display a marker including at least one of a text or an image for guiding an operation of a user to establish a communication connection with the external user terminal, based on authentication on the electronic apparatus being performed by capturing the electronic apparatus outputting the marker by the external user terminal, receive a signal confirming authentication on the electronic apparatus from the external user terminal, and establish a communication connection with the external user terminal in response to the signal.
