Digital Key Sharing via Relay Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing digital keys, such as digital car keys, are inconvenient, complicated, and pose security risks due to the difficulty in confirming the intended recipient and potential interception or misuse of the shared key.
Innovation Solution
A communication technique involving an electronic device that receives provisioning data for creating a digital key, which includes an interface circuit, processor, and memory, performs operations like encryption, decryption, and verification processes using a relay computer, host computer, and verification computer to securely share the digital key by hashing contact information and using one-time passwords, ensuring secure and convenient delivery to the intended recipient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing share procedures are used to transfer a digital key, then the key can be shared with other individuals, but the process becomes complicated and security risks increase
Solution Approach 1:
The patent introduces a relay device as an intermediary component that facilitates secure key sharing between the first electronic device (owner) and the second electronic device (recipient). The relay device receives the digital key from the owner's device, verifies the recipient's identity through contact information matching, and forwards the key to the intended recipient. This intermediary approach simplifies the sharing process by automating verification steps and eliminating the need for multiple communication channels, while simultaneously enhancing security through controlled key distribution.
2Adaptability or versatility
If existing share procedures are used to transfer a digital key, then the key can be shared with other individuals, but security risks increase due to potential interception or misuse
Solution Approach 1:
The patent implements a feedback mechanism where the relay device verifies the recipient's identity by comparing contact information (such as phone numbers or email addresses) provided by the recipient against contact information associated with the digital key on the owner's device. This verification feedback ensures that the key is only shared with the intended recipient, preventing unauthorized access and misuse. The feedback loop confirms successful key delivery and provides audit trails for security monitoring.
3Adaptability or versatility
If existing share procedures are used to transfer a digital key, then the key can be shared with other individuals, but the process becomes inconvenient and frustrating
Solution Approach 1:
The patent enables self-service functionality where the recipient can independently initiate the key reception process by providing their contact information to the relay device. The system automatically performs verification by matching this information against the owner's device records, eliminating the need for the owner to manually guide each step of the sharing process. This self-service approach significantly improves convenience while maintaining security through automated verification protocols.

AI summary
During operation, a host computer may receive, associated with an electronic device, contact information of a user of the electronic device and input data for a hash function. Then, the host computer may verify the electronic device based at least in part on an identifier of the electronic device and stored device information. Alternatively, the host computer may jointly perform a verification process with a verification computer to verify the electronic device. Next, the host computer may generate a hashed version of the contact information based at least in part on the input data and the hash function. Moreover, the host computer may provide, addressed to a partner computer, the hashed contact information and a request for the provisioning data. Furthermore, the host computer may selectively receive, associated with the partner computer, the provisioning data, and the host computer may selectively provide, addressed to the electronic device, the provisioning data.
