Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional password management methods are time-consuming and do not allow for the sharing of cryptographic libraries, requiring users to manually manage and update passwords for different applications, which is inefficient and insecure.
Innovation Solution
A method and system that utilize a sharing cryptographic library on terminal devices to store application program identification codes, biological characteristic information, and corresponding account names and passwords, enabling secure and rapid password sharing between devices by matching biological characteristics for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional password management methods are used with master password and password files, then password storage is possible, but password sharing between devices is not available and manual searching is time-consuming
Solution Approach 1:
The patent merges password management functionality across multiple terminal devices by establishing a shared cryptographic library that can be accessed by authorized devices. The biometric authentication system combines facial recognition technology with the password management system, allowing users to access their password information across different devices without manual searching, thus resolving the contradiction between password sharing capability and time consumption.
Solution Approach 2:
The patent introduces a cryptographic library as an intermediary component that stores password information in an encrypted format. This cryptographic library acts as a mediator between the user and the password information, allowing secure access across devices through biometric authentication while eliminating the need for manual password searching and enabling seamless password sharing.
2Adaptability or versatility
If conventional password management methods are used, then password storage is possible, but cryptographic libraries cannot be shared between devices
Solution Approach 1:
The patent creates a universal cryptographic library system that can be accessed by multiple terminal devices through biometric authentication. The facial recognition system provides a unified authentication mechanism that works across different devices, allowing the cryptographic library to serve multiple functions: secure storage, cross-device sharing, and automated password retrieval, thus enabling cryptographic library sharing without proportionally increasing system complexity.
Solution Approach 2:
The patent replaces traditional mechanical password entry systems with biometric facial recognition technology. This substitution eliminates the need for complex manual authentication processes across devices while enabling secure cryptographic library sharing. The biometric system provides a more intuitive and secure method for accessing shared password information across multiple terminals.
3Productivity
If manual password management is used, then password security can be maintained through user control, but password updates and management become time-consuming
Solution Approach 1:
The patent implements a self-service password management system where the cryptographic library automatically handles password storage, encryption, and retrieval. When a user needs to access password information, the system automatically authenticates through facial recognition and retrieves the required password without requiring manual searching or updating. This self-service mechanism significantly improves password management efficiency while reducing the time users spend on password-related tasks.

AI summary
A method of pushing passwords, a pushing system and a terminal device are provided. The method includes establishing a sharing cryptographic library which stores a plurality of application program identification codes, account names and passwords, receiving first biological characteristic information of a user, and simultaneously receiving a push request including second biological characteristic information and a current application program identification code. An account name and a password of the current application program identification code from the sharing cryptographic library is read, and the account name and the password is pushed to a second terminal device when the first biological characteristic information matches with the second biological characteristic information.
