Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems rely on centralized servers that are vulnerable to security threats, lacking a secure and portable method for storing and verifying user identities across different platforms.
Innovation Solution
A blockchain-based identity and transaction platform that encrypts user identity information and stores it in a distributed network, enabling secure, portable, and accessible user profiles using multi-stage verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized servers are used for authentication, then system control and management are simplified, but security vulnerability increases
Solution Approach 1:
The patent divides the centralized authentication system into distributed blockchain nodes. Each node stores encrypted user identity information independently, eliminating the single point of failure in centralized servers while maintaining system control through consensus mechanisms.
Solution Approach 2:
The patent introduces encryption as an intermediary layer between the blockchain storage and user identity information. The encryption service decrypts stored encrypted identity information only when needed for authentication, providing security without compromising the distributed storage architecture.
2Reliability
If user identity information is stored in blockchain, then security and portability are improved, but data accessibility and retrieval complexity increase
Solution Approach 1:
The encryption service acts as an intermediary that handles the complexity of decrypting blockchain-stored identity information. It receives decryption requests, retrieves encrypted data from the blockchain, decrypts it using stored keys, and returns the readable information, thereby simplifying the data retrieval process for authentication operations.
3Reliability
If multi-stage verification is implemented, then authentication security is enhanced, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-storing encrypted user identity information and encryption keys in the blockchain during user registration. This preparation eliminates the need for time-consuming data retrieval and decryption operations during actual authentication, reducing processing time while maintaining multi-stage verification security.
4Reliability
If encryption is applied to user identity information, then data protection is improved, but storage and processing requirements increase
Solution Approach 1:
The patent stores only the encrypted version of user identity information in the blockchain, creating a copy that appears as random data. This encrypted copy provides data protection while occupying minimal storage space compared to storing multiple versions or unencrypted data with associated metadata.

AI summary
Systems, methods, and computer-readable media for computer-implemented authentication platforms are described herein. In an example approach, a user is enrolled in a computer-implemented authentication platform. The enrollment process includes digitally encrypting an image of a user, storing the digitally encrypted image of the user in a blockchain as part of a user profile of the user, generating (using the digitally encrypted image of the user) an identifier of the user, and storing the identifier of the user in the blockchain as part of the user profile of the user. Subsequently, the user is authenticated. The authentication process includes retrieving the digitally encrypted image of the user from the blockchain (using the identifier of the user to retrieve the digitally encrypted image of the user) and decrypting the digitally encrypted image of the user using a decryption token.
