NFC Authentication Code Sharing for Multi-Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiency and poor user experience due to the need for repeated authentication when accessing applications on multiple devices, such as mobile phones and laptops, even when already logged in on another device.
Innovation Solution
A method for NFC authorization sharing between devices, where a user logs into an application on one device, generates an authentication code, and then shares it with another device via NFC, allowing access without re-authentication by using an access token obtained from an authentication server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user logs into an application on one device, then the user can access the application on that device, but the user must reauthenticate when accessing the same application on another device
Solution Approach 1:
The patent introduces an intermediary authentication server that mediates between multiple devices and the application. When a user authenticates on one device, the server issues an authentication code that can be shared with other devices via NFC, eliminating the need for re-authentication while maintaining security. This intermediary enables seamless access across devices without compromising the authentication process.
2Adaptability or versatility
If a user uses multiple devices with the same application, then the user can access applications on different devices, but the user experience becomes inefficient due to repeated authentication
Solution Approach 1:
The authentication system is designed with universality to work across multiple devices. The authentication server can issue codes that are valid on any device, and the NFC sharing mechanism enables the same authentication to be transferred universally. This allows a single authentication to serve multiple devices, making the system adaptable to various device combinations while improving user experience.
Solution Approach 2:
The authentication server acts as a universal intermediary that manages authentication across different device types (mobile phones, tablets, laptops). It provides a common authentication mechanism that works regardless of which device the user is accessing from, thereby achieving multi-device adaptability without degrading user experience.
3Reliability
If a user authenticates separately on each device, then security is maintained, but the authentication process becomes cumbersome and time-consuming
Solution Approach 1:
The authentication server serves as a secure intermediary that issues authentication codes based on verified user credentials. These codes can be shared via NFC between devices, allowing the system to maintain security through centralized verification while improving efficiency by enabling single authentication to access multiple devices. The server ensures that only authenticated users can obtain sharing codes, maintaining security without requiring repeated logins.
Solution Approach 2:
Instead of requiring users to re-authenticate on each device, the system creates a copy of the authentication code that can be transferred via NFC. This copying approach allows the same authentication to be replicated across devices without compromising security, as the codes are generated and managed through the secure authentication server. This dramatically improves authentication efficiency while maintaining security standards.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless access to applications across devices without the need for re-authentication, improving user experience by simplifying the authentication process and reducing the burden of multiple logins.
Implementation Method 1
The first device is then placed near the second device and the second authentication code is passed to the second device through near field communication (NFC)
Data Source
AI summary
A computer implemented method and system for near field communication authentication sharing techniques is disclosed. The method comprises providing user credentials to access an application on a first device; sending a request to share the authentication with a second device; in response to the request, receiving an authentication code; and transmitting the authentication code to the second device, wherein sharing enables the second device to access the application on the second device without providing user credentials.
