Cryptographic Proof for Verifiable Digital Identity Responses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Social media and online platforms face challenges in verifying the authenticity of responses due to the ability of users to submit multiple responses using aliases or accounts, making response mechanisms unreliable.
Innovation Solution
A method is introduced that generates a cryptographic proof based on unique verifiable credentials, allowing users to prove the authenticity of their responses without revealing the credentials, and enables recipients to verify the authenticity of responses by using a hash value and cryptographic proof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users can submit multiple responses using aliases or accounts, then the quantity of responses increases, but the authenticity and reliability of responses deteriorates
Solution Approach 1:
The patent introduces cryptographic proofs and hash values as intermediaries between the user's digital identity and the response submission. These cryptographic elements serve as mediators that verify authenticity without requiring direct exposure of sensitive identity information, thus maintaining reliability while allowing multiple legitimate responses from different users
Solution Approach 2:
The patent replaces traditional mechanical verification methods (such as manual identity checking or centralized authentication systems) with cryptographic verification mechanisms. By using cryptographic proofs, hash functions, and digital signature verification, the system achieves automated, reliable authenticity verification that can handle multiple responses efficiently without compromising trust
2Reliability
If cryptographic proofs are generated and transmitted with each response, then the authenticity verification capability is improved, but the data transmission volume and processing complexity increases
Solution Approach 1:
The patent performs preliminary cryptographic operations by pre-generating digital signatures and hash values for user identities before response submission. These pre-computed cryptographic elements are stored and reused, eliminating the need to perform complex cryptographic operations for each individual response, thus reducing processing complexity while maintaining verification capability
Solution Approach 2:
The patent uses hash values as simplified copies of the original cryptographic proofs. Instead of transmitting and processing the full cryptographic proof data, the system transmits compact hash values that can be efficiently verified against stored reference hashes, significantly reducing data transmission volume and processing complexity while preserving authenticity verification

AI summary
The present disclosure provides a method for responding to published content, a method for assessing a response to published content, computer programs, non-transitory machine-readable media, and apparatuses therefor. The method for responding to published content comprises generating, based on one or more unique verifiable credential of a first digital identity and information related to a second digital identity, a cryptographic proof for proving that the first digital identity is holder of the one or more unique verifiable credential. The cryptographic proof is indicative of the second digital identity and a hash value of the 10 one or more unique verifiable credential. Further, the method comprises outputting data indicative of a response to the published content together with the cryptographic proof and the hash value.
