Blockchain Tokens for Cross-Platform User Account Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of enabling account portability across different computing platforms, particularly in virtual environments like the Metaverse, is hindered by privacy and unauthorized access concerns, as existing systems struggle to authenticate users effectively.
Innovation Solution
Utilizing blockchain technology and cryptographic tokens, such as non-fungible tokens (NFTs), to create and manage user accounts that can be securely accessed across multiple platforms, with an access control system encoding and encrypting functions for interaction with services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication systems are used to access services across different platforms, then service access is simplified, but user privacy and security are compromised due to unauthorized access concerns
Solution Approach 1:
The patent introduces a cryptographic token as an intermediary between the user account and the service platform. The token contains encrypted authentication data and service-specific instructions, allowing the service to be accessed without exposing the user's actual credentials. This mediator enables cross-platform access while maintaining security by never transmitting or storing plain-text authentication information.
Solution Approach 2:
The system creates a cryptographic copy of the authentication credentials embedded within a token structure. Instead of using the original credentials directly, a replicated version is generated that contains only the necessary service-specific instructions and encrypted authentication data. This copy can be safely transmitted and used across different platforms without compromising the original credential security.
2Adaptability or versatility
If user accounts are made portable across multiple platforms, then cross-platform service usage is enabled, but authentication security and access control become more complex
Solution Approach 1:
The authentication system is segmented into distinct functional components within the token: user identification data, service-specific instructions, encrypted authentication credentials, and validation logic. Each segment serves a specific purpose and can be independently processed. This segmentation allows the complex authentication process to be broken down into manageable steps that can be executed across different platforms without requiring complex integration.
Solution Approach 2:
The cryptographic token is designed as a universal credential that can function across multiple different service platforms and computing devices. It contains a standardized structure that can be validated by any service provider that supports the token format, enabling portability while maintaining consistent security protocols. The token serves multiple functions: authentication, authorization, and secure communication across platform boundaries.
3Reliability
If cryptographic tokens are used to secure user access, then unauthorized access is prevented, but the system requires complex cryptographic operations and key management
Solution Approach 1:
The cryptographic token is pre-generated and pre-configured with all necessary authentication data and service instructions before the user needs to access a service. The complex cryptographic operations, including key generation and encryption, are performed in advance during token creation. When the user needs to access a service, the pre-configured token can be directly used without requiring real-time cryptographic computation or complex key management during the access operation.

AI summary
Methods and systems are described here for porting accounts to multiple computing platforms. Blockchain technology may be used and in particular cryptographic tokens (e.g., non-fungible tokens) may be used. A cryptographic token may represent a user account and may enable usage of the cryptographic token to provide portability of the user account. An access control system may be used to perform operations described herein. The access control system may receive a request for using, at a computing platform, an account of the user. The request may include an identifier of a cryptographic token. The access control system may determine, based on the cryptographic token, that access to the user account may be permitted and the request may be fulfilled.
