Identity Metric Protection Module Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of identity metrics, such as voice fingerprints and three-dimensional models, across networks poses risks of identity theft due to potential interception and unauthorized use, particularly in communication technologies that recreate user identities.
Innovation Solution
Implementing a custom module on computing devices to encrypt and decrypt identity metrics, which includes requesting and using decryption keys from a server to ensure only authorized applications can access and use the decrypted metrics, thereby preventing unauthorized copying and interception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identity metrics are transmitted across networks for communication recreation, then communication functionality is improved, but security against identity theft deteriorates
Solution Approach 1:
The system performs preliminary encryption of identity metrics before transmission across the network. The encryption occurs at the source device before the data leaves the secure environment, ensuring that even if interception occurs during transmission, the stolen data remains unusable without the decryption key.
Solution Approach 2:
The system introduces an intermediary encryption layer between the identity metric and the network transmission channel. The encrypted form acts as an intermediary representation that maintains the functional utility of the identity metric for communication recreation while preventing unauthorized access to the original unencrypted data.
2Object-affected harmful factors
If identity metrics are encrypted before transmission, then security is improved, but access complexity increases
Solution Approach 1:
The system implements self-service encryption where the originating device automatically encrypts the identity metric using its own private key without requiring manual intervention or complex external key management infrastructure. The receiving device similarly performs automatic decryption using stored public keys, reducing operational complexity.
Solution Approach 2:
The encryption system is designed to be universally applicable to different types of identity metrics (voiceprints, 3D models, facial recognition data) and different communication platforms. The same encryption/decryption mechanism works across various devices and applications, reducing the need for multiple specialized systems.
3Speed
If decryption keys are stored on receiving devices, then access speed is improved, but security vulnerability increases
Solution Approach 1:
The cryptographic key system is segmented into multiple components distributed across different devices. Each device holds only a portion of the key material (public keys or encrypted forms), while the complete decryption capability requires collaboration between multiple parties. This segmentation prevents any single device from having full access to compromise the system.
Solution Approach 2:
Different portions of the key system are stored with different security characteristics in different locations. Sensitive key material remains in secure enclaves or hardware security modules on specific devices, while less sensitive information (public keys, encrypted forms) is stored in more accessible locations. This creates a hierarchy of local security qualities that balances speed and security.

AI summary
A computer-implemented method for protecting identity metrics may include (i) receiving, by a computing device and from an originating device, an identity metric encrypted by an identity metric protection module on the originating device, where the identity metric includes biometric data about an operator of the originating device, (ii) requesting, by an identity metric protection module on the computing device, a decryption key from an identity metric protection server, (iii) receiving, by the identity metric protection module, the decryption key from the identity metric protection server, (iv) decrypting, by the identity metric protection module, the identity metric with the decryption key received from the identity metric protection server, and (v) providing the decrypted identity metric to an application on the computing device that uses the identity metric to convey a communication from the operator of the originating device. Various other methods, systems, and computer-readable media are also disclosed.
