Two-Dimensional Code Segmentation for Secure Identification Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for accessing and updating identification data, particularly biometric data, are expensive, time-consuming, and vulnerable to theft, as they require physical documents with two-dimensional barcodes, and storing such data centrally raises privacy concerns.
Innovation Solution
A method that groups identification data into complementary elementary files, transforms them into two-dimensional codes, and distributes these codes across separate media, with one group held by the individual and the other accessible by the entity, ensuring secure access and updating without regenerating physical documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification data is stored in a central database, then access control is improved, but personal data protection deteriorates
Solution Approach 1:
The patent divides identification data into multiple separate two-dimensional codes, where each code contains only a portion of the complete identification information. The central database stores reference codes rather than complete identification data. This segmentation ensures that even if the database is accessed, complete personal data cannot be reconstructed without the physical codes held by the individual.
2Reliability
If biometric data is stored centrally, then authentication capability is improved, but data security deteriorates
Solution Approach 1:
Biometric data is fragmented across multiple two-dimensional codes that the individual possesses. The central database only stores reference authentication codes without complete biometric information. Authentication requires combining the physical codes with database references, preventing centralized storage of sensitive biometric data while maintaining authentication capability.
3Reliability
If physical identification documents are issued, then identification reliability is improved, but update efficiency deteriorates
Solution Approach 1:
The system uses two-dimensional codes as digital copies of identification data that can be regenerated and redistributed electronically. When updates are needed, new codes are generated and provided to the individual without requiring physical document reissuance. The central database stores reference codes that can be quickly updated and matched against new codes.
4Ease of operation
If complete identification data is stored on one medium, then data accessibility is improved, but theft risk deteriorates
Solution Approach 1:
Identification data is divided into multiple separate two-dimensional codes that must be combined to reconstruct complete information. This segmentation reduces theft risk because a single compromised code does not expose complete identification data. The central database stores additional reference codes that further distribute the data across multiple locations.

AI summary
The invention concerns a method for generating an access for an entity (10) to identification data of a person (12), the method comprising the steps of: - grouping the identification data into an identification file, - partitioning the identification file into two mutually complementary elementary files, - transforming each elementary file into a two-dimensional code, characterised in that the method comprises a step of dividing the two-dimensional codes into two groups of codes stored on separate media, the identification data of the person (12) only being accessible at the time of reuniting the first and second groups of codes stored on each of said media.
