Matryoshka Encrypted Image for Mutual Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital identity management systems are vulnerable to ID theft, as text-based authentication methods are susceptible to hacking and phishing attacks, leading to unauthorized use and leakage of personal information, with difficulties in real-time monitoring and allocation of responsibility.
Innovation Solution
An encrypted image with a matryoshka structure is used in a multi-layer authentication system, where encrypted images are nested within each other, requiring hierarchical extraction of authentication data, incorporating user and server biometric information, and hardware details to enhance security and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-based authentication (user ID and password) is used, then ease of operation is improved, but security against hacking and phishing attacks deteriorates
Solution Approach 1:
The authentication system is segmented into multiple layers with different authentication methods. The first layer uses text-based user ID and password for initial access, while the second layer uses image-based authentication with matryoshka structure for enhanced security. This segmentation allows the system to maintain ease of operation at the entry level while providing strong security at the critical authentication level.
Solution Approach 2:
The patent employs a matryoshka (nested doll) structure where encrypted images are embedded within encrypted images. Each encrypted image contains authentication data and may contain another encrypted image within it, creating multiple nested layers. This nesting provides progressive authentication where each layer must be successfully verified, significantly enhancing security while maintaining a user-friendly interface.
2Ease of operation
If centralized digital ID management is implemented, then convenience in use is improved, but vulnerability to large-scale information leakage at service provider side increases
Solution Approach 1:
The centralized authentication system is segmented into multiple independent authentication layers. Each layer handles specific authentication data stored in separate encrypted images. This segmentation ensures that even if one layer's data is compromised, other layers remain secure, preventing large-scale information leakage while maintaining centralized management convenience.
Solution Approach 2:
The system implements prior cushioning by encrypting authentication data in multiple nested layers before storage and transmission. The matryoshka structure ensures that authentication data is protected by multiple encryption layers, providing a cushion against potential security breaches. Even if external hackers access the service provider's database, they cannot easily extract authentication information due to the nested encryption structure.
3Reliability
If multiple authentication layers are implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent uses a nested doll (matryoshka) structure where encrypted images are embedded within encrypted images in a hierarchical manner. Each encrypted image contains authentication data and may contain another encrypted image within it. This nesting provides progressive authentication where each layer must be successfully verified, significantly enhancing security while maintaining a unified system architecture that manages complexity through hierarchical organization.
Solution Approach 2:
The authentication system is designed with multi-functionality to handle various authentication scenarios using the same nested image structure. The system can accommodate different types of authentication data (user credentials, biometric information, device identifiers) within the same matryoshka framework, reducing overall system complexity by providing a universal authentication mechanism that serves multiple security functions.

AI summary
The present invention relates to an encrypted image with a matryoshka structure and a mutual agreement authentication system and method using the same. The encrypted image with a matryoshka structure is used in authentication in an authentication system having a plurality of layers and comprises: a first encrypted image which can be opened by only a server of any one layer of the authentication system; and a second encrypted image which can be opened by only a server of another layer distinguished from the any one layer, wherein any one sealed encrypted image of the first and second encrypted images is embedded and sealed in the other encrypted image.
