BEISIGN Identity Binding and Settlement Bus for Verifiable Clearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telephone numbers and SIM-bound identities are vulnerable to spoofing and cross-channel impersonation, while existing financial rails lack verifiable envelopes for secure transaction and clearing across heterogeneous ledgers.
Innovation Solution
A dual-signature protocol binds a subject decentralized identity (DID) and an institutional identity (EID) using a secure enclave and AI guardian, with risk evaluation and zero-knowledge validation, and supports SIM-less session establishment, layer-2 batching, and post-quantum cryptographic encapsulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional telephone numbers and SIM-bound identities are used, then communication establishment is simple, but vulnerability to spoofing and impersonation increases
Solution Approach 1:
The identity verification system is segmented into multiple independent components: decentralized identity (DID) for user ownership, institutional identity (EID) for organization verification, secure enclave for cryptographic operations, and AI guardian for risk assessment. Each component operates independently but contributes to the overall verification reliability without requiring complete system redesign.
Solution Approach 2:
The patent introduces intermediary components including the secure enclave that acts as a trusted mediator between user devices and networks, the AI guardian that mediates risk assessment between transaction parties, and the evidence envelope that mediates verification across heterogeneous ledgers. These intermediaries enhance reliability without directly increasing end-user complexity.
2Reliability
If existing financial rails are used, then transaction processing is established, but lack of verifiable envelope across heterogeneous ledgers occurs
Solution Approach 1:
The evidence envelope is designed as a universal data structure that can carry verification information across multiple heterogeneous ledgers and financial rails simultaneously. It incorporates multiple signature types (primary and secondary), timestamping, and metadata that make it adaptable to different ledger requirements while maintaining a single consistent verification mechanism.
Solution Approach 2:
The verification system uses composite cryptographic structures combining multiple signature algorithms, timestamping mechanisms, and metadata layers within the evidence envelope. This composite approach allows the same envelope structure to satisfy requirements of different ledgers and financial protocols without requiring separate verification systems for each.
3Reliability
If dual-signature protocol with secure enclave and AI guardian is implemented, then identity binding reliability improves, but system complexity increases
Solution Approach 1:
The secure enclave performs preliminary cryptographic key generation and signature creation before transactions occur. The AI guardian conducts preliminary risk assessment and determines whether secondary signatures are needed. This preliminary action reduces real-time complexity by pre-computing verification requirements and establishing trust boundaries in advance.
Solution Approach 2:
The secure enclave operates as a self-service component that autonomously manages cryptographic operations including key generation, signature creation, and verification without requiring external intervention. The AI guardian similarly autonomously assesses risk and makes decisions about secondary signature requirements, reducing the operational complexity burden on users and system administrators.
4Ease of operation
If SIM-less identifiers are used, then session establishment flexibility improves, but authentication security challenges increase
Solution Approach 1:
The system creates cryptographic copies of identity verification data in the form of verifiable claims and evidence envelopes that can be transmitted and validated without requiring the original SIM card or physical device. These cryptographic copies maintain authentication reliability while enabling SIM-less operation and flexible session establishment across different devices and networks.

AI summary
A computer-implemented protocol, BEISIGN, generates verifiable records for communications and financial messages by combining risk evaluation and presence challenge with dual signatures from a secure enclave and a guardian module. The record is bound to an evidence envelope referencing a TimeTape snapshot and supports revocation, rollback, and zero-knowledge validation. Overlays for SIP/WebRTC and ISO 20022 allow early trust establishment and cross-chain clearing via a Settlement Bus that performs layer-2 batching, atomic netting, and deterministic rollback across CBDC, stablecoin, and banking rails. The protocol enables printable verifiable reports with QR-based verification and governs licensing of data via tokens.
