Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user information is redundantly stored across multiple centralized systems, then each system can independently access and verify user data, but security is compromised and digital waste increases
Solution Approach 1:
The patent introduces a blockchain-based digital identity system as an intermediary layer between users and multiple platforms. Instead of storing user information across multiple centralized systems, the system creates a single source of truth on the blockchain that platforms can verify without directly accessing or storing sensitive user data. This mediator approach resolves the contradiction by maintaining system independence through cryptographic verification while eliminating security vulnerabilities associated with redundant storage.
Solution Approach 2:
The patent extracts sensitive user information from centralized storage systems and places it in a decentralized blockchain environment. By taking out the core authentication data from vulnerable centralized databases and storing it immutably on the blockchain, the system maintains the ability for platforms to verify user identities while removing the security risks of redundant storage across multiple systems.
2Adaptability or versatility
If user information is redundantly stored across multiple centralized systems, then each system can operate independently, but network bandwidth is over-utilized and digital waste increases
Solution Approach 1:
The patent uses cryptographic copies (hashes) of user identity data stored on the blockchain rather than duplicating actual user information across multiple systems. Platforms can verify user identities by checking cryptographic proofs and references to the blockchain, eliminating the need to transfer or store redundant user data locally. This approach maintains system independence while dramatically reducing network bandwidth consumption.
3Speed
If centralized systems store user information locally, then access is fast and direct, but user identities are vulnerable to theft and reuse attacks
Solution Approach 1:
The patent performs preliminary authentication by having users verify their identities once against the blockchain network, which then issues cryptographic proofs (such as zero-knowledge proofs or signed statements). These pre-verified credentials can be quickly presented to multiple platforms without requiring repeated authentication queries to the blockchain, thus maintaining fast authentication speeds while ensuring high security through the immutability and cryptographic strength of the blockchain.
Data Source
AI summary
Blockchain-based systems and methods for providing secure digital identities and affiliations for users via digital tokens. A set of digital tokens are generated that are sharable on a distributed computer network. The set of digital tokens are affiliated with an entity or a person. One or more of the digital tokens are provided to one or more users of the distributed computer network, where the one or more users comprise at least a first user, and where the first user is provided a first token selected from the one or more of the digital tokens. The first user is identified as affiliated with the entity or the person based on a receipt of an indication that the first user is associated with the first token.
