Trans-Account Device Key Transfer in Benefit Denial Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Secondary functions of electronic devices are often inaccessible to secondhand purchasers, reducing the device's value, as the initial retailer typically does not provide the necessary means to fulfill conditions required for accessing these functions.
Innovation Solution
A system and method for transferring access rights between users, involving the generation of a transaction record with a digital signature, verification through a registry network, and the transmission of a device key to the new user's device, allowing them to issue commands to the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access rights are restricted to initial purchasers only, then device security is improved, but device value to secondhand purchasers deteriorates
Solution Approach 1:
The patent introduces a registry network as an intermediary between the initial purchaser and secondhand purchaser. The registry network verifies ownership through transaction records and facilitates secure device key transfer, enabling access rights to be transferred to new owners while maintaining security through cryptographic verification
Solution Approach 2:
The patent extracts the device key from being permanently bound to the initial purchaser and makes it transferable through the registry network. The device key is separated from the original owner and can be reassigned to new owners through verified transactions, allowing the device to change hands while maintaining security
2Adaptability or versatility
If device key is transferred to secondhand purchaser, then device value is improved, but security risk increases
Solution Approach 1:
The registry network acts as a trusted intermediary that verifies the legitimacy of device key transfers. It maintains a record of authorized transactions and ensures that only verified secondhand purchasers receive device keys, reducing security risks while enabling value transfer
Solution Approach 2:
The patent replaces physical security mechanisms with cryptographic verification. Instead of relying on physical possession or simple authentication, the system uses digital signatures, hash functions, and cryptographic key pairs to verify ownership and authorize device key transfer, providing enhanced security
3Reliability
If complex verification process is implemented, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The registry network automatically performs verification of transaction records and device key transfers without requiring manual security checks. The system self-verify ownership through cryptographic proofs and automatically facilitates the key transfer process, reducing operational complexity while maintaining security
Solution Approach 2:
The system performs preliminary verification of transaction records and ownership status before allowing device key transfer. By pre-validating the transaction through the registry network and checking cryptographic signatures in advance, the system ensures security is maintained while the actual transfer process remains simple for users

AI summary
Techniques described herein are directed toward enabling a transfer of access rights for an electronic device between users. In embodiments a transferee device may receive a first request to obtain access rights for an electronic device associated with a transferor device. The transferor device may receive a second request to grant access rights for the electronic device. Embodiments may include receiving, at the transferee device, a device key associated with the electronic device and storing the device key in association with the electronic device. Embodiments may further include issuing a command from at least one of the transferee or transferor devices to unlock the electronic device, and causing the electronic device to comply with the command to unlock if the at least one of the transferee or transferor devices that issues the command has access to the device key when the command is issued.
