Verification Fingerprint for Data Access Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data access verification systems lack effective methods for ensuring the authenticity and copyright protection of data, particularly for sensitive information, as they fail to provide detailed tracking and management of data access requests and unauthorized access control.
Innovation Solution
A system and method for verifying data access using an independent verification fingerprint, which involves generating a verification fingerprint for original data, embedding it into the data, and storing access information in a verification database, allowing for detailed tracking and management of data access requests through a service module, verification module, and data module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If watermarking technology is used to verify data access, then data authenticity and copyright protection are improved, but the system lacks detailed tracking and management capabilities for data access requests
Solution Approach 1:
The patent segments the verification system into distinct modules: a service module for receiving access requests, a verification module for generating fingerprints, a data module for embedding fingerprints into data, and a verification database for storing access information. This segmentation enables both authenticity verification and detailed access tracking to coexist by distributing functions across specialized components.
Solution Approach 2:
The patent introduces an intermediary verification fingerprint as a mediator between the original data and the verification database. This fingerprint contains embedded access information that bridges the gap between data authentication and access tracking, allowing the system to verify both data authenticity and maintain detailed access records simultaneously.
2Reliability
If verification fingerprint is embedded into original data, then data integrity verification is improved, but device complexity increases due to multiple modules and database structures
Solution Approach 1:
The patent merges multiple verification functions into a unified fingerprint structure that is embedded directly into the data. The verification fingerprint combines authentication information, access tracking data, and integrity verification elements into a single integrated component, reducing the need for separate complex subsystems while maintaining comprehensive verification capabilities.
Solution Approach 2:
The patent uses copying by creating a verification fingerprint that is a derived representation of the original data's access and integrity information. This fingerprint copy contains essential verification data without requiring storage of the entire original data set, simplifying the system structure while maintaining verification reliability.
3Ease of operation
If detailed access information is stored in verification database, then data access management is improved, but storage requirements and processing time increase
Solution Approach 1:
The patent extracts only the essential access verification information into the fingerprint structure stored in the database, rather than storing complete access request details. This extraction approach maintains detailed access management capabilities while minimizing storage requirements and processing time by focusing only on the critical verification data needed for authentication and tracking.
Data Source
AI summary
This application relates to a system for verifying data access and a method thereof. In one aspect, the system includes a service module for receiving a data access request for an original data from a client, and sending a first verification data to the client. The system also includes a verification module for receiving a first data eigenvalue corresponding to the original data from the service module, and generating a first verification fingerprint corresponding to the first data eigenvalue. The system further includes a data module for generating the first verification data by receiving the first verification fingerprint to embed into the original data, and generating a first integrity value by hashing the first verification data. The system further includes a verification database for storing data access information comprising the first data eigenvalue, the first verification fingerprint and the first integrity value in one record identified as the original data.
