Cryptographic signing, hash chaining, and monotonic sequence counters ensure any modification to an AI decision record is mathematically detectable.
InferTrust™ (Patent Pending) creates tamper-evident audit trails through a combination of cryptographic techniques applied at the moment of AI inference. The system ensures that any modification to a decision record,whether accidental or deliberate,is mathematically detectable.
Each decision record is digitally signed using asymmetric cryptography. The signing keys are isolated from the application layer, meaning that application code, database administrators,and system operators cannot generate valid signatures. Only InferTrust™'s signing infrastructure, operating at the inference boundary, can produce authentic signatures.
Decision records are linked using hash chains, where each record includes a cryptographic hash of the previous record. This creates an ordered sequence where modifying any historical record would invalidate the hash references in all subsequent records, making tampering not just detectable but immediately obvious.
The integrity of any InferTrust™ decision record can be independently verified using the public key corresponding to the signing key. This means auditors, regulators,and legal teams can confirm record integrity without relying on InferTrust™'s infrastructure or the organization's own systems. The proof is in the mathematics, not in organizational attestations.
