Digital Verification Fingerprint Embedding in Data Inactive Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data access management systems face challenges in securely embedding digital verification fingerprints within original data without modifying it, particularly for sensitive information like personal or medical data, where access verification is crucial.
Innovation Solution
A system and method for embedding a digital verification fingerprint by inserting it into an embeddable location of the original data, using a data module and interpretation module to generate verification data, with a preset database storing embedding location lists based on data type information, allowing independent verification and minimal modification of the original data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a watermark is inserted into the original data to verify data access, then data verification capability is improved, but the original data is modified
Solution Approach 1:
The patent segments the data structure into active areas (containing meaningful data) and inactive areas (containing insignificant values or padding). The verification fingerprint is inserted only into inactive areas, thereby segmenting the modification locations to preserve the integrity of the original meaningful data while still enabling verification.
Solution Approach 2:
The patent applies local quality by treating different areas of the data differently. Inactive areas are designated as suitable for modification with verification fingerprints, while active areas remain protected. This localized approach allows verification functionality to be added without compromising the quality or integrity of the original data content.
2Reliability
If verification fingerprint is inserted into active area, then verification functionality is achieved, but data meaning is altered
Solution Approach 1:
The patent divides the data into active areas (which carry meaningful information) and inactive areas (which contain insignificant values). By segmenting the data this way, the system can insert verification fingerprints into inactive areas without altering or losing the meaningful information in active areas.
Solution Approach 2:
The patent converts the previously useless inactive areas (which contained insignificant values) into beneficial spaces for storing verification fingerprints. What was originally waste space or padding is now transformed into a functional area that enables data verification without affecting the meaningful data.
3Adaptability or versatility
If embedding location is not predetermined, then flexibility is improved, but data modification increases
Solution Approach 1:
The patent performs preliminary action by pre-identifying and designating inactive areas within the data structure before any verification fingerprint insertion occurs. These inactive areas are marked in advance as suitable embedding locations, allowing flexible placement of verification fingerprints while ensuring that only predetermined safe areas are modified.
Data Source
AI summary
A system includes a data module for receiving an original data and a verification fingerprint, and generating a verification data by inserting the verification fingerprint into an embeddable location of the original data. The system also includes an interpretation module for generating data type information of the original data, and deriving an input-enabled location from an embedding location preset list of the original data, wherein the input-enabled location is included in an inactive area of the original data. The system further includes a preset database for storing the embedding location preset list according to the data type information.
