Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manage multiple passwords manually, then security may be maintained, but complexity and difficulty of management increase significantly
Solution Approach 1:
The patent introduces a password manager system as an intermediary between the user and multiple digital identities. The system automatically generates, stores, and manages multiple passwords and digital identities, eliminating the need for users to manually handle complex password management while maintaining security through cryptographic methods.
Solution Approach 2:
The system enables automatic password generation and management without continuous user intervention. It self-manages the creation, storage, and rotation of multiple digital identities and passwords, reducing management complexity while maintaining security through automated cryptographic operations.
2Ease of operation
If existing password management software is used, then password storage is simplified, but active management of multiple digital identities and hierarchical management capabilities are lacking
Solution Approach 1:
The patent creates a multi-functional system that not only stores passwords but also actively manages multiple digital identities, generates hierarchical key structures, and provides cryptographic operations. The system serves multiple purposes including password management, identity management, and security operations, making it adaptable to various digital identity requirements.
Solution Approach 2:
The system segments digital identity management into hierarchical levels with master keys and derived keys, allowing different levels of access and control. This segmentation enables flexible management of multiple digital identities with different security requirements while maintaining ease of operation through structured organization.
3Adaptability or versatility
If big data technologies are applied for user profiling, then service personalization improves, but user privacy is infringed upon
Solution Approach 1:
The patent introduces digital identities as intermediaries between users and service providers. Instead of exposing real personal information, the system uses generated digital identities to interact with services, enabling service personalization through the intermediary while protecting the user's actual privacy by preventing direct exposure of personal data.
Solution Approach 2:
The system creates copies of identity information in the form of digital identities that can be used for service interactions. These digital identity copies enable service personalization and data collection by third parties without exposing the user's real personal information, thus protecting privacy while maintaining service functionality.

AI summary
The present disclosure provides a personal identity management system and method. The method includes a client and a service end. The client uses a user-specified keyword to perform hierarchical management on keys, and the service end accepts the digital identity information from the client and performs digital signature and further displays the information in public. In the method of the present disclosure, available digital identities can be generated securely and quickly with an unlimited quantity, such that the user can perform switching between multiple digital identities so as to achieve the effect of combating the tracking for the digital identities and protecting the user privacy better. Furthermore, in a scenario where identity verification and access control are required, verification can be completed by providing public key and signature.
