Verified Anonymous Personas for Distributed Token Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain-based NFTs compromise owner anonymity, increasing the risk of malicious targeting and unwanted attention due to included ownership information.
Innovation Solution
A secure virtual personalized network (SVPN) is established with encryption keys and virtual machines to enable secure communication and transactions, allowing users to define verified personas and maintain anonymity while ensuring identity verification for trusted parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFTs include ownership information to facilitate owner identification and ownership transfer, then ownership verification is improved, but owner anonymity is compromised
Solution Approach 1:
The patent segments the identity system into multiple layers: public key identifiers visible on blockchain, verified persona attributes stored in decentralized storage, and private personal information kept confidential. This segmentation allows ownership verification through public keys and verified personas while protecting personal anonymity by separating identifiable information from transaction data.
Solution Approach 2:
The patent introduces verified personas as intermediaries between the user's real identity and the blockchain system. These personas act as mediators that can be verified by counterparties through decentralized identification protocols, enabling trust and ownership verification without exposing the user's actual personal information or creating malicious targeting risks.
2Loss of information
If blockchain stores all transaction data publicly for transparency, then transaction traceability is improved, but user privacy is compromised
Solution Approach 1:
The patent extracts personal identifiable information from the public blockchain ledger and stores it in decentralized storage systems accessible only to authorized parties. Transaction hashes and verified persona identifiers remain on-chain for transparency, while sensitive personal data is taken out and protected off-chain, maintaining transaction traceability without privacy exposure.
Solution Approach 2:
The patent moves personal information from the public dimension (blockchain ledger visible to all) to a private dimension (decentralized storage accessible only to authorized parties). This dimensional separation allows transaction transparency on the public blockchain while protecting user privacy through off-chain storage of sensitive information.
3Reliability
If decentralized identification is implemented to verify personas, then trust establishment is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal verified persona system that can be used across multiple blockchain networks and applications. The same verified persona identifier and verification mechanism work consistently throughout the decentralized ecosystem, reducing the need for separate identification systems in each application and thereby reducing overall system complexity while maintaining trust establishment.
Data Source
AI summary
A computer that provides one or more verified personas for a distributed token (such as a non-fungible token or NFT) of a first user is described. Notably, the computer may provide the one or more verified personas for the first user that are based at least in part on their account(s) with a provider of a secure, virtual private network (SVPN) of the first user. Consequently, the identity of the first user may be known to the provider. However, the one or more verified personas may obfuscate the known identity of the first user when conducting one or more discrete secure transactions (such as a transaction associated with a cryptocurrency or the NFT) using or associated with the distributed token. In particular, the first user may associate or link the one or more verified personas with the distributed token, thereby providing the benefits of privacy and selective (as-needed) identification.
