Talking Head Digital Identity Authentication via Blockchain Hash Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current talking head digital identity authentication systems fail to adequately protect talking heads and associated content from data loss, security breaches, malicious attacks, hacking, viruses, financial losses, and intellectual property theft, especially over distributed networks.
Innovation Solution
A talking head digital identity immutable dual authentication system using a blockchain-based approach, where talking head and talking head show files are stored on nodes of a distributed network, with hash values downloaded from a blockchain for verification, ensuring the integrity and origin of the content through dual authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If talking head files are stored on distributed network nodes, then data loss and security breaches are reduced, but system complexity increases
Solution Approach 1:
The system segments the authentication process into two independent parts: (1) storing talking head files on distributed network nodes, and (2) storing hash values on a blockchain. This segmentation allows the system to leverage the security benefits of distributed storage while using the blockchain only for verification, thereby improving reliability without proportionally increasing overall system complexity.
Solution Approach 2:
The blockchain acts as an intermediary verification layer that does not store the actual talking head files but only stores their hash values. This intermediary approach enables security verification through hash comparison without requiring the blockchain to handle large media files, thus improving security protection while keeping the blockchain's role simple and manageable.
2Reliability
If hash values are stored on blockchain for dual authentication, then content integrity is ensured, but storage costs and processing time increase
Solution Approach 1:
The system performs preliminary hashing of talking head files and stores the hash values on the blockchain in advance. When verification is needed, the system simply retrieves and compares these pre-stored hash values rather than re-hashing entire files, thus ensuring content integrity while minimizing processing time during verification operations.
3Use of energy by moving object
If distributed network nodes store talking head files, then bandwidth requirements are reduced, but network security vulnerabilities increase
Solution Approach 1:
The system creates a cryptographic copy (hash value) of the talking head files and stores this copy on the blockchain. This copying approach allows the original files to be distributed across network nodes for efficient bandwidth usage, while the cryptographic copy provides security verification without exposing the actual content to potential security vulnerabilities in the distributed network.

AI summary
A talking head digital identity immutable dual authentication method for use over a distributed network, comprising: downloading talking head and talking head show files from nodes of a distributed network; downloading hash values of a talking head and talking head show from a blockchain; sending a hash of a publisher's identification from the blockchain to a name lookup service; retrieving and confirming the identity of the publisher from the name look up service; recalculating hash values of the talking head and talking head show; comparing the recalculated hash values of the talking head and talking head show with the hash values of the talking head and talking head show retrieved from the blockchain; starting playback of the talking head show if the hash values received from the blockchain match the recalculated hash values of the talking head and the talking head show retrieved from the nodes of the distributed network.
