NFT-Based Digital Wallet Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and techniques that can facilitate automatic restriction or access to assets associated with a digital wallet, particularly in the context of blockchain transactions, where existing solutions lack robustness in managing access based on various factors such as user identity, location, and activity levels.
Innovation Solution
A system that utilizes non-fungible tokens (NFTs) and artificial intelligence to assess and determine if predefined factors are satisfied, thereby automatically granting or restricting access to digital assets within a digital wallet, including the creation of NFTs based on user proximity, activity, and social media profiles, and utilizing these tokens to provide access or charge against digital wallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control methods are used for digital wallet assets, then ease of operation is maintained, but security and reliability are insufficient
Solution Approach 1:
The patent introduces NFTs as intermediary tokens that mediate access to digital wallet assets. These NFTs encode access conditions and act as a bridge between the asset owner and potential accessors, enabling secure automated access control without direct complex cryptographic protocols for end users. The NFT serves as a trusted intermediary that automatically enforces access rules based on predefined factors.
Solution Approach 2:
The system implements self-service access control where the NFT automatically evaluates access requests against predefined factors (location, time, device, etc.) without requiring manual intervention from the asset owner. The smart contract embedded in the NFT autonomously determines whether to grant or deny access, eliminating the need for traditional manual authentication processes while enhancing security.
2Reliability
If manual access approval processes are implemented, then security is improved, but productivity and ease of operation deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple access factors (location, time, device characteristics, user identity) into the NFT before access is needed. When an access request occurs, the system automatically evaluates these pre-set conditions without requiring real-time manual approval, thus maintaining security while enabling rapid transaction processing.
Solution Approach 2:
The system incorporates feedback mechanisms where the NFT continuously monitors access attempts and compares them against the predefined factors. The smart contract provides immediate feedback by automatically accepting or rejecting access requests based on whether the current conditions match the predefined criteria, eliminating delays associated with manual approval processes.
3Reliability
If comprehensive access factors are evaluated, then reliability and security are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The patent uses NFTs as simplified copies or representations of complex access control logic. Instead of requiring users to directly manage multiple access factors and security protocols, the system creates NFT tokens that encapsulate these complex rules in a simple, transferable format. Users interact with the NFT as a single object rather than managing multiple security parameters individually.
Solution Approach 2:
The NFT serves multiple functions simultaneously: it acts as an access control mechanism, an authentication tool, a condition evaluator, and a transaction mediator. This multi-functionality consolidates what would otherwise require multiple separate systems into a single universal token, reducing operational complexity while maintaining comprehensive security checks across all access factors.

AI summary
Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, a system, comprises a non-transitory memory comprising instructions; and one or more hardware processors coupled to the non-transitory memory and configured to read the instructions to cause the system to perform operations comprising: detecting a request from a first user to access one or more digital assets of a first digital wallet of a second user; in response to detecting the request, determining whether to provide access to the one or more digital assets to the first user based on one or more factors, wherein the one or more factors includes a location of the first user, a location of the second user, or one or more characteristics of the first user; and restricting the first user from accessing the one or more digital assets based on the one or more factors.
