Digital Fingerprint Key Records for Secure Object Provenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current personal property registries rely on affixed identifiers or general descriptions, making them vulnerable to theft and counterfeiting, with no centralized system providing certainty of identification and provenance without these external markers.
Innovation Solution
A method and system that uses a physical object's inherent digital fingerprint to grant access to digital records, linking the fingerprint to the object's digital pedigree for secure access control, allowing multiple key objects to manage access rights and update digital records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If affixed identifiers or general descriptions are used in personal property registries, then object identification and registration are enabled, but the system becomes vulnerable to theft and counterfeiting
Solution Approach 1:
The patent extracts the identification function from external affixed identifiers and general descriptions, and relocates it to the inherent digital fingerprint of the physical object itself. This eliminates the vulnerability chain starting with external markers while preserving the ability to uniquely identify and register personal property.
Solution Approach 2:
The physical object's inherent digital fingerprint serves as its own unique identifier without requiring external affixed identifiers. The object essentially identifies itself through its intrinsic properties, making the system more reliable and resistant to counterfeiting since the fingerprint cannot be replicated or transferred.
2Reliability
If centralized registries without affixed identifiers are created, then provenance verification is improved, but device complexity increases
Solution Approach 1:
The patent creates a digital copy of the physical object's inherent fingerprint and stores it in the centralized registry. This digital copy serves as the basis for provenance verification without requiring complex physical tagging or marking systems, thus improving reliability while keeping the physical system simple.
Solution Approach 2:
The digital fingerprint acts as an intermediary between the physical object and the centralized registry. It bridges the gap between physical property identification and digital record-keeping, enabling provenance verification through a simple digital representation rather than complex physical markers.
3Reliability
If digital fingerprints are used for access control, then security against unauthorized access is improved, but measurement and detection difficulty increases
Solution Approach 1:
The system automatically acquires the digital fingerprint from the physical object's inherent properties without requiring manual intervention or complex measurement equipment. The object's intrinsic characteristics provide the fingerprint directly, simplifying the detection and measurement process while maintaining high security.
Data Source
AI summary
A key object record is initialized a the data store to store data associated with a physical key object. A digital fingerprint of the physical key object is stored in the key object record. Another digital record is created in the data store that is not the key object record. The digital record is linked to the digital fingerprint of the physical key object. The linking is arranged to provide secure control access to the linked digital record. A tendered access key is received via a programmatic interface or user interface, and the data store is queried based on the tendered access key to identify a matching digital fingerprint of a key object. In a case that the querying identifies the matching digital fingerprint of the key object within a prescribed level of confidence, access to the linked digital record secured by the key object is granted.
