Blockchain Verification for AI Model Trustworthiness

The patent introduces blockchain as an intermediary layer between AI model developers and users. The blockchain stores verified characteristics and audit trails of AI models, serving as a trusted mediator that enables external verification without interfering with model operation. This resolves the contradiction by providing a third-party verification mechanism that enhances trustworthiness while maintaining deployment productivity.

The patent implements preliminary verification of AI model characteristics before deployment by storing validated model attributes on the blockchain. This preliminary action ensures that models are pre-audited for trustworthiness and explainability, allowing critical applications to deploy with confidence without compromising productivity through post-deployment verification delays.

The patent creates a universal blockchain-based verification system that can validate multiple AI model characteristics (accuracy, bias, explainability, compliance) through a single platform. This multi-functional approach improves trustworthiness across different AI applications without proportionally increasing complexity, as the same blockchain infrastructure serves multiple verification purposes simultaneously.

The patent stores copies of verified AI model characteristics and audit information on the blockchain rather than requiring direct access to the complex verification infrastructure. Users can obtain trusted verification data through simple blockchain queries, reducing the perceived complexity while maintaining high trustworthiness through immutable recorded evidence.

The patent extracts only the essential verified characteristics of AI models (accuracy metrics, bias indicators, explainability scores, compliance certifications) and stores them on the blockchain, rather than storing complete model datasets or raw verification data. This extraction approach maintains explainability by preserving key model attributes while minimizing storage requirements through selective data capture.

The patent transforms complex AI model verification data into standardized, structured blockchain records with fixed schemas. By converting multidimensional verification information into standardized fields (model ID, verification timestamp, characteristic scores, compliance status), the system improves explainability through consistent data structures while reducing storage complexity through dimensional normalization.
