Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing encryption methods are time-consuming, difficult to use, and susceptible to circumvention, especially in portable devices, as they require shared private keys and are not effectively secured biometrically.
Innovation Solution
A biometrically secured system and method for transparently encrypting and decrypting data using a computer program that creates an encryption key based on user biometric data, allowing seamless encryption and decryption with minimal user effort, and storing data in a secure repository.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encryption software is used, then data security is improved, but user effort and time consumption increase significantly
Solution Approach 1:
The system automatically performs encryption and decryption operations without requiring user intervention. The biometric authentication system self-manages the entire encryption process, including key generation and data protection, eliminating the need for users to manually configure or operate encryption software.
Solution Approach 2:
The system pre-generates encryption keys based on biometric data before actual data encryption is needed. By preparing cryptographic credentials in advance through biometric enrollment, the system eliminates time-consuming key generation steps during actual encryption operations.
2Reliability
If traditional encryption with shared private keys is used, then data protection is achieved, but vulnerability to key interception and circumvention increases
Solution Approach 1:
The system extracts the private key from the communication process entirely. Instead of sharing private keys between parties, each user's biometric data serves as their own private key that never leaves their device, eliminating the security vulnerability of key transmission and storage.
Solution Approach 2:
The system implements asymmetric cryptography where each user has a unique biometric-based key pair. The public key can be freely shared while the private key remains securely tied to the user's biometric data, creating an asymmetric security model that prevents key interception attacks.
3Ease of operation
If encryption keys are stored on portable devices, then data accessibility is improved, but susceptibility to physical circumvention increases
Solution Approach 1:
The system replaces physical key storage with biometric-based cryptographic authentication. Instead of storing encryption keys on portable storage devices that can be physically accessed, the system uses the user's biometric data (fingerprint, iris, facial recognition) as the key, which cannot be physically extracted or copied.
Solution Approach 2:
The system changes the fundamental parameter of key storage from physical (files on devices) to biological (human characteristics). By transforming the key from a storable digital object to an inherent physical trait of the user, the system eliminates the possibility of physical circumvention while maintaining accessibility.
Data Source
AI summary
A computer program for enabling biometrically secured, transparent encryption and decryption provides a user interface that allows a user to drag and drop files into and out of a secure repository, wherein the program automatically encrypts files transferred into the repository and automatically decrypts files transferred out of the repository. The user can transfer file folders into the repository, wherein the program encrypts all of the files within the folder and retains the original file/folder structure, such that individual files can be moved within the repository, moved out of the repository, and opened or executed directly from the repository. The program requires the user to submit biometric data and grants access to the secure repository only if the biometric data is authenticated. The program generates an encryption key based at least in part on biometric data received from the user.
