Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The secure transfer of payment tokens between computing devices poses security risks due to incompatibility of security mechanisms across different devices and operating systems, making it challenging to manage authorization and authentication effectively.
Innovation Solution
The implementation of a system that uses web Bluetooth APIs to establish a secure connection between devices, allowing users to transfer payment tokens while ensuring authentication and authorization through biometric interfaces and cryptographic encryption, ensuring that only authorized users can access and use the payment tokens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If payment tokens are transferred to multiple devices, then user accessibility and convenience are improved, but security risks and vulnerability to unauthorized access increase
Solution Approach 1:
The system segments the token transfer process into distinct phases: authentication phase (verifying user identity via biometrics), authorization phase (checking device compatibility and user permissions), and transfer phase (actual token movement). This segmentation allows each phase to be secured independently, maintaining security while enabling multi-device access.
Solution Approach 2:
The system introduces an intermediary authentication mechanism that acts as a mediator between the user, the source device, and the target device. This intermediary verifies biometric credentials and device compatibility before allowing token transfer, ensuring that security is maintained even as tokens are distributed across multiple devices.
2Adaptability or versatility
If security mechanisms are made compatible across all devices, then transferability and versatility are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The system implements a universal authentication framework that works across different device types and operating systems. By using standardized biometric authentication methods and common cryptographic protocols, the system achieves broad compatibility without requiring device-specific security implementations, thus maintaining versatility while controlling complexity.
Solution Approach 2:
The system adapts security parameters dynamically based on the target device's capabilities. Instead of implementing all possible security mechanisms on every device, the system adjusts authentication and encryption parameters to match the device's security features, achieving compatibility across diverse devices without unnecessary complexity.
Data Source
AI summary
Various embodiments are generally directed to the secure transfer of account tokens between devices. For example, a first device may receive an account token stored on a second device using web Bluetooth application programming interfaces (APIs). As another example, the second device may push the account token to the first device.
