Identity Mapping Encryption via User-Controlled Key Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques fail to effectively protect the privacy of real users by allowing unauthorized access to the mapping between real and synthetic identities, particularly vulnerable to security breaches and coercion.
Innovation Solution
A system where the real user maintains exclusive access to a cryptographic key, using strong encryption (AES 256-bit) and secure storage (like iOS Keychain) to encrypt and decrypt synthetic identity mappings, ensuring only the user can unlock the mapping between their real and synthetic identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the platform hosts synthetic identities and stores mapping data, then users can create and manage multiple identities for compartmentalization, but the mapping between real users and synthetic identities becomes vulnerable to security breaches and unauthorized access
Solution Approach 1:
The patent extracts the mapping data from the platform's control and stores it exclusively in the user's device using local cryptographic key pairs. The platform no longer holds the ability to decrypt or access the mapping between real users and synthetic identities, effectively removing the vulnerability point while preserving the identity compartmentalization functionality.
Solution Approach 2:
The patent introduces cryptographic intermediaries (public-key infrastructure, encrypted tokens, and signed assertions) as mediators between the user and the platform. These cryptographic mechanisms enable the platform to verify user identity and manage synthetic identities without directly accessing or storing the sensitive mapping data, thus maintaining security while enabling functionality.
2Productivity
If the platform operator stores unencrypted mapping data for service operation, then the service can function efficiently, but the data becomes accessible to external parties through coercion or security breaches
Solution Approach 1:
The patent extracts the sensitive mapping data from the platform's storage and relocates it to the user's device. The platform retains only encrypted representations or cryptographic proofs that enable service operation without exposing the actual mapping data, thus eliminating the harm of unauthorized access while maintaining productivity.
Solution Approach 2:
The patent transforms the mapping data from a plaintext state that the platform can read into an encrypted state where only the user's private key can decrypt it. This parameter change (from readable to encrypted) prevents unauthorized access while allowing the platform to perform cryptographic operations on the encrypted data for service delivery.
3Reliability
If strong encryption and local key storage are implemented, then identity mapping security is greatly improved, but the system complexity and implementation difficulty increase
Solution Approach 1:
The patent implements self-service cryptography where the user's device automatically generates key pairs, encrypts mapping data, and manages cryptographic operations without requiring manual intervention or complex configuration. The system handles the cryptographic complexity automatically, reducing the burden on users while maintaining strong security.
Solution Approach 2:
The patent uses universal cryptographic standards and protocols (such as JWT, OAuth, and standard public-key infrastructure) that are already widely supported by existing systems and libraries. This allows the implementation to leverage existing multi-functional cryptographic tools rather than building custom complex systems, reducing implementation difficulty while maintaining security.
Data Source
AI summary
A machine has a processor and a memory storing instructions executed by the processor to issue a challenge in response to a first request, evaluate a response to the challenge to establish confirmation that the first request originated from a human user, issue a user identification in response to the confirmation, store the user identification with encrypted identity data, receive a second request that includes the user identification, and return the encrypted identity data in response to the second request.
