Blockchain One-Time Private Key for Anonymous Personal Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online and offline service systems require users to input and manage personal information directly, leading to risks of leakage, misuse, and lack of control over how their information is used, with no clear monitoring or consent mechanisms for sensitive data.
Innovation Solution
A system and method utilizing a one-time private key based on a blockchain of proof of use, where personal information is stored and managed in a distributed manner using alternative authentication keys, allowing users to access services anonymously and monitor usage without directly providing personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users directly input and provide personal information to service providers, then services can be accessed and membership can be registered, but personal information may be leaked, stolen, or misused due to hacking, hooking, or improper handling by service providers
Solution Approach 1:
The patent introduces a blockchain network as an intermediary between users and service providers. Personal information is stored on the blockchain rather than being directly transmitted to service providers. Users can access services by providing only a reference to their blockchain-stored information, eliminating direct exposure of personal data to service providers while maintaining service accessibility
Solution Approach 2:
The patent segments personal information into two parts: sensitive personal information stored securely on the blockchain, and non-sensitive access information (such as public keys or references) used for service access. This segmentation allows users to access services without exposing their sensitive personal information to service providers
2Adaptability or versatility
If users register and log in to multiple online services, then various services can be utilized, but it becomes difficult to monitor and control how personal information is used across different services
Solution Approach 1:
The patent implements a feedback mechanism where the blockchain network records and tracks all accesses to personal information. Users can query the blockchain to see exactly which services have accessed their information, when, and for what purpose. This provides continuous feedback on information usage, enabling users to monitor and control service providers' access to their personal data
3Productivity
If sensitive information is continuously updated for optimal service, then service quality is improved, but input and storage standards differ across services making updating and sharing complicated
Solution Approach 1:
The patent creates a universal blockchain-based storage system that can handle all types of personal information with a single standardized approach. The blockchain provides a common data structure and access protocol that works across all services, eliminating the need for service-specific input and storage standards. This universal system simplifies information updates and sharing across different services while maintaining service quality

AI summary
The present disclosure relates to a system and a method for providing personal information for an online service system. More particularly, the present disclosure relates to a system and a method for providing personal information using a one-time private key based on a blockchain of proof of use, wherein personal information is registered and stored in a distributed manner in a blockchain network, services in online and offline service systems are used by using alternative authentication identification information that is anonymous and includes a public key to access the personal information in the blockchain network, and for membership registration and login, only the alternative authentication identification information is used to receive a service, become a member of a service, and to log in, without providing the personal information.
