System and method for policy-gated execution of AI workflows using evidence-anchored authorization and runtime enforcement.

Absstract of: AU2026201325A1

A computer-implemented system and method for policy-gated execution of artificial intelligence workloads. The system intercepts execution requests at pre-execution enforcement points, constructs a Context Graph — a cryptographically bound, multi-party authorisation directed acyclic graph (DAG) anchored to a hardware root of trust — representing the execution context including workload identity, request parameters, data classifications, execution environment attributes, and requester authorisation scope. The Context Graph is evaluated against configurable policy rules expressed in a declarative policy language to produce a decision. For permitted executions, the system issues authorisation tokens cryptographically bound to a context digest, policy version, nonce, and validity interval. All decisions are recorded in an append-only, hash-chained evidence ledger enabling independent verification. In advanced embodiments, policy evaluation executes within hardware-isolated secure enclaves using Trusted Execution Environment technology, and the system enforces procedural requirements including multi-party authorisation and time-delayed execution for high-risk actions. Authorisation tokens and attestation bindings may utilise post-quantum signature schemes conforming to FIPS 204 (ML-DSA) or FIPS 205 (SLH-DSA). eb e b Patent A — The Gatekeeper System and method for policy-gated execution of AI workflows using evidence-anchored authorization and runtime enforcement BRIEF DESCRIP

SYSTEM FOR RECORDING VERIFICATION KEYS ON A BLOCKCHAIN

Absstract of: US20260303614A1

0000 Systems and methods described herein relate to the execution of locking transactions in a blockchain system. In the context of smart contracts, it may be advantageous to have a public record (e.g., recorded on a blockchain) of a proof of correct execution of a circuit published by a worker and the verification key, thereby allowing anyone (e.g., nodes of the blockchain) to verify validity of the computation and proof. However, there are challenges to recording large blocks of data (e.g., large keys that may comprise multiple elliptic curve points) on the blockchain. For example, in a Bitcoin-based blockchain network, a protocol that utilizes standard transactions may be constrained to locking scripts and unlocking scripts that are collectively not larger than a first predetermined size limit, and the size of a redeem script (if utilized) may be limited to being no more than a second predetermined size limit.

Authenticated Message Delivery With Controlled Routing Gateway

Absstract of: US20260303364A1

A system controls outbound electronic communications attributed to blockchain-verified senders. A verification service validates a cryptographic signature for a wallet address or public key, determines ownership or control of a blockchain-recorded asset or identity, and creates a verified sender record. A binding-record data store stores subscription binding records associating recipient identifiers with verified sender records and opt-in state. For a proposed outbound communication, a routing gateway service determines a current per-recipient authorization decision and, only for an allow decision, generates an authorization artifact bound to communication, recipient, channel, sender, binding, policy, and timing fields. A delivery adapter process validates the authorization artifact before retrieving or using transport credentials, creating payloads, writing queues, calling provider APIs, signing webhooks, resolving push tokens, writing inbox records, or opening network connections. Non-bypass controls and fresh retry authorization prevent unauthorized or stale transport invocation.
