Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manage multiple passwords manually, then security can be maintained through memorization, but it becomes extremely difficult and time-consuming to manage a large number of passwords
Solution Approach 1:
The system enables automatic password generation and management without requiring user memorization. The password management apparatus automatically generates secure passwords, manages multiple digital identities, and performs hierarchical key management, allowing the system to serve itself rather than requiring manual user intervention for each password operation.
Solution Approach 2:
The patent introduces a password management apparatus as an intermediary between the user and multiple digital identities. This intermediary component handles the complexity of managing numerous passwords and cryptographic keys, providing a simplified interface to users while maintaining high security standards through automated password generation and hierarchical key management.
2Ease of operation
If existing password management software is used, then password storage is simplified, but the capability to actively provide multiple digital identities and perform hierarchical management is missing
Solution Approach 1:
The password management apparatus is designed with multi-functionality to handle diverse digital identity management tasks. It can actively provide multiple digital identities, perform hierarchical key management across different levels, generate passwords, and manage cryptographic operations, making it a universal solution for various digital identity scenarios rather than a single-purpose tool.
Solution Approach 2:
The system implements hierarchical segmentation of key management into multiple levels. The password management apparatus divides key management into hierarchical structures where different levels of keys serve different purposes, enabling fine-grained control and management of digital identities while maintaining security through the segmented hierarchical architecture.
3Productivity
If big data technologies such as user portrait technology are applied, then data processing capability is enhanced, but user privacy is frequently infringed upon
Solution Approach 1:
The system segments user data into multiple digital identities, each with its own cryptographic key pair. This segmentation allows data processing capabilities to be maintained while preventing privacy infringement, as each digital identity can be managed independently and selectively disclosed, preventing the consolidation of complete user profiles that would enable harmful profiling.
Solution Approach 2:
The password management apparatus acts as an intermediary between users and data processing systems. It enables data processing capabilities while protecting privacy by managing digital identities and cryptographic operations, allowing users to control what information is disclosed to external systems without exposing their complete personal data profile.
Data Source
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.
