Autofill Mechanism for Secure Authentication via External Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices, especially those unfamiliar with remote controls or touch screens, face inconvenience when entering information, and the mixing of authentication information among multiple users introduces security issues when multiple users share the same device.
Innovation Solution
An autofill function that allows an electronic device to receive and automatically enter input information from a connected external device, ensuring secure and convenient authentication without direct user input, by using communication circuitry to request and receive input information and process it on the input screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information is stored in memory of the TV for easy access, then information entry convenience is improved, but security deteriorates due to mixing of authentication information among multiple users
Solution Approach 1:
The patent segments authentication information by associating it with specific external electronic devices (smartphones, tablets, wearables) rather than storing it generically in TV memory. Each external device maintains its own authentication credentials, creating isolated segments that prevent mixing between users while enabling convenient autofill functionality.
2Reliability
If manual information entry is required on TV, then security is maintained, but ease of operation deteriorates for users unfamiliar with remote controls or touch screens
Solution Approach 1:
The patent introduces external electronic devices (smartphones, tablets, wearables) as intermediaries that handle the complex task of information entry. These devices serve as mediators between the user and the TV system, providing authentication information through autofill functionality while maintaining security through controlled information sharing.
Solution Approach 2:
The patent replaces manual mechanical input methods (remote control button pressing, touch screen interaction) with automated electronic information transfer. The external device automatically transmits authentication information to the TV system, substituting the mechanical input process with an electronic autofill mechanism.
3Ease of operation
If autofill function uses information from external devices, then ease of operation is improved, but device complexity increases due to communication circuitry and protocols
Solution Approach 1:
The patent implements universal communication protocols that allow the TV system to interact with multiple types of external devices (smartphones, tablets, wearables) through a single standardized interface. This multi-functionality enables the system to handle diverse devices without requiring separate communication circuits for each device type, thereby limiting the increase in complexity.

AI summary
An electronic device and method are disclosed, the method including a communication circuitry, a memory storing an application, a display, and a processor operatively connected with the communication circuitry, the memory, and the display. The processor executes the method, including: receiving a request to execute the application, outputting an information input screen relevant to executing the application on the display based on the request, receiving at least one piece of input information to be entered into the information input screen, from a specific external electronic device via the communication circuitry, and automatically entering the at least one piece of input information into the information input screen.
