Touch Panel Signal Coupling for Cross-Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the burden of managing multiple accounts and passwords across different devices and services, and existing security methods are either unreliable or lack portability and sufficient security.
Innovation Solution
The method involves using touch-sensitive devices to communicate signature information through their touch panels via electric field coupling, allowing for secure authentication by transmitting and receiving signals between the devices, thus eliminating the need for traditional account and password management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional account and password management is used, then security control is provided, but the burden of managing multiple accounts and passwords increases
Solution Approach 1:
The patent implements a universal authentication system where a single signature created on one device can be verified across multiple different devices and service websites. The signature, generated through touch panel interaction, serves as a multi-functional authentication credential that replaces the need for separate accounts and passwords for each service, thereby reducing management burden while maintaining security control.
Solution Approach 2:
The patent creates a digital copy of the user's signature that can be transmitted and verified across different devices. The signature information is captured, stored, and replicated as authentication data that can be presented to multiple service providers without requiring the user to recreate or remember multiple credentials, thus eliminating the management burden of multiple accounts and passwords.
2Ease of operation
If browser auto-save of accounts and passwords is used, then ease of access is improved, but security level decreases
Solution Approach 1:
The patent replaces the mechanical storage method of browser auto-save (storing credentials in device memory) with a touch-based signature verification system. Instead of relying on device-specific stored credentials that can be accessed by anyone with device access, the system uses dynamic signature capture and verification through touch panel electrode interactions, providing both ease of access and enhanced security.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism - the signature verification system - that mediates between the user and the service website. Rather than directly using stored passwords that compromise security, the system uses the signature as an intermediary credential that is harder to compromise but equally convenient to use, thereby improving security while maintaining ease of access.
3Ease of operation
If fingerprint identification or face identification is used, then account and password management is eliminated, but portability and device-specific security are limited
Solution Approach 1:
The patent creates a universal signature-based authentication system that works across multiple devices and service websites, unlike device-specific biometric systems. The signature, captured through touch panel interaction, can be verified on any device equipped with the verification system, providing both the convenience of eliminating password management and the portability needed for cross-device access.
4Ease of operation
If touch panel signal transmission is used for authentication, then portability and ease of operation are improved, but technical complexity increases
Solution Approach 1:
The patent utilizes the touch panel's existing electrodes and signal transmission capabilities to perform authentication functions. The touch panel hardware that already exists for user interface purposes is made to serve dual functions - both display/input and authentication - without requiring additional dedicated hardware components. This self-service approach reduces technical complexity while maintaining portability and ease of operation.

Function Achieved in This Case
This approach provides a secure and portable authentication method that reduces the burden of managing multiple accounts and passwords, enhancing security by using existing touch panel hardware for near-field wireless communication, which is more efficient and cost-effective than conventional NFC technologies.

AI summary
A non-transitory computer readable storage medium is provided. The non-transitory computer readable storage medium has stored therein instructions, which when executed by a mobile device, cause the mobile device to: provide, at a processing circuit, a signal to a transmitting electrode of a first touch panel; transmit, at the transmitting electrode, the signal to a receiving electrode of a second touch panel of a computing device; and perform further operation with the computing device when the signal corresponds to a signature stored in the computing device.
