Device Identifier Access Code Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring access rights between electronic devices are insecure, as data transfer can occur unauthorizedly, compromising the security of access-right transfers.
Innovation Solution
A computer-implemented method that uses device-identifying codes to enhance security by generating and transforming access codes, ensuring that access rights are transferred securely between devices, with at least a portion of the access code representing a unique device identifier, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If access rights are transferred between electronic devices, then data transfer capability is improved, but security is worsened due to unauthorized transfer risks
Solution Approach 1:
The system performs preliminary actions by embedding device identifiers in access codes before transfer, and verifying these identifiers at the receiving end. This preventive measure ensures that only authorized devices can successfully transfer and use access rights, eliminating the need for post-transfer security checks and enabling secure transfer without compromising productivity
Solution Approach 2:
The patent introduces device identifiers as an intermediary element that mediates between the transferring device and the accessed resource. This intermediary verification mechanism ensures that the access right is bound to specific devices, preventing unauthorized transfers while maintaining smooth data transfer capability between authorized devices
2Reliability
If device identifiers are embedded in access codes, then security is improved, but access code complexity is worsened
Solution Approach 1:
The patent merges the device identifier with the access code into a single unified structure. Rather than treating them as separate elements requiring individual management, the identifier is embedded within the access code itself, simplifying the overall system architecture while maintaining security verification capabilities
Solution Approach 2:
The access code serves multiple functions simultaneously: it grants access rights, identifies the target device, and verifies authorization. This multi-functionality eliminates the need for separate verification protocols and reduces system complexity despite the enhanced security requirements
Data Source
AI summary
A method for detection and use of device identifiers to enhance the security of data transfers between electronic devices. A first electronic device can transmit access data to a second electronic device. The access data can be associated with a first access code that can be generated based at least in part on data representing a device identifier of the first electronic device. A device identifier can uniquely identify the first electronic device from a plurality of electronic devices. Transferring the access data can involve transforming the first access code into a second access code that can include data representing a device identifier associated with the second electronic device. Transforming the first access code into the second access code can facilitate access to a resource associated with the access data for a second user, but not for a first user.
