Decentralized Testing Cryptographic Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In decentralized medical testing, the lack of a trusted authority to verify test results leads to concerns about false reports, necessitating the involvement of a trusted party in every test, which is inefficient and may not ensure authenticity.
Innovation Solution
A method and system that utilize a secure test apparatus with a unique identifier, encoded with an error correction code and cryptographic function, allowing authenticatable results to be recorded in a data repository without the need for a trusted authority's involvement, using cryptographic functions and error correction codes to ensure the authenticity and integrity of test results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trusted party is involved to certify test results, then the authenticity and reliability of test results is improved, but the device complexity and inefficiency increases due to requiring trusted party participation in every test
Solution Approach 1:
The patent extracts the trusted certification function from the central authority and embeds it directly into the test device through cryptographic credentials. The test device now independently verifies its own authenticity using embedded certificates, eliminating the need for external trusted party involvement in each test while maintaining result authenticity.
Solution Approach 2:
The test device performs self-verification of its authenticity using embedded cryptographic credentials. The device autonomously generates and verifies its own certification through digital signatures and cryptographic proofs, without requiring external intervention from a trusted authority for each test operation.
2Reliability
If a trusted party is involved in every test, then the authenticity of results is improved, but the productivity and efficiency deteriorates due to the involvement requirement
Solution Approach 1:
The cryptographic credentials, digital certificates, and verification mechanisms are pre-configured and embedded into the test device during manufacturing. This preliminary setup enables the device to perform independent authenticity verification without requiring real-time intervention from a trusted authority, significantly improving testing efficiency while maintaining authenticity.
3Productivity
If decentralized testing is implemented without trusted authority, then the productivity and ease of operation is improved, but the reliability and risk of false reports worsens
Solution Approach 1:
The patent introduces cryptographic digital signatures and blockchain technology as intermediary mechanisms that enable decentralized verification without requiring a central trusted authority. These cryptographic intermediaries provide mathematical proof of authenticity, allowing any participant to verify test result validity independently while maintaining high reliability in a decentralized environment.

AI summary
A method of cryptographically secured decentralized testing includes receiving, by a computing device and from a secure test apparatus, an output of a cryptographic function of a secret test result identifier, authenticating the output, and recording, in a data repository, an indication of a test result as a function of the output.
