The patent application covers 63 claims ranging from broad method claims to narrow domain-specific implementations across healthcare, autonomous vehicles, finan
The InferTrust™ patent application is structured with defense in depth. It includes broad method claims covering the core innovation of inference-time cryptographic signing, apparatus claims covering the system architecture, and narrow domain-specific claims covering implementations in healthcare, autonomous vehicles, manufacturing, and financial services.
"Is this just logging with encryption?" No. Encryption protects confidentiality. Signing proves integrity. The novelty is cryptographic signing at inference time using a device-bound hardware key before any application, network, or UI process can access the output. No prior art combines these elements.
"Does prior art exist for cryptographic audit logs?" Cryptographic audit logs exist, but no known system binds model version, confidence score, policy hash, input feature hash, decision action, timestamp, and sequence counter into one signed record at the moment of inference on the local device.
"Is the execution boundary theoretical?" No. The patent covers multiple proven implementation mechanisms including Trusted Execution Environments (Intel SGX, ARM TrustZone), hardware memory protection, OS process isolation, and secure enclaves.
"Would blockchain solve this?" Blockchain provides consensus-based immutability for distributed systems. InferTrust™ proves what happened at the point of inference on a specific device. These are different problems with different solutions.
