Current Industry Standard
STEP 01
User Intent
User initiates a transfer of $10,000 to Supplier A via a secured web session.
STEP 02
The "Intent Swap"
Malware (RAT/Browser-Bot) intercepts the request. It silently changes the destination to Hacker X.
STEP 03
Verification Gap
Bank sends an OTP. The user enters it, assuming it validates their intent. The bank only verifies the person, not the data.
STEP 04
Execution
Because the session is encrypted and MFA is valid, the bank processes the modified hacker request.
STEP 05
Outcome: Loss
The fraud is successful. Post-audit reveals a "valid" transaction with no cryptographic proof of the user's original intent.
The NonaShield Standard
STEP 01
Cryptographic Binding
As the user types, NonaShield creates a Unique Hash of the $10,000 + Supplier A.
STEP 02
Hardware Signing
The hash is signed inside the phone's Secure Enclave (TEE). This signature is physically inseparable from the data.
STEP 03
Continuous Attestation
The system checks for screen-sharing or malware. Even if the device is compromised, the Signing Key remains dark and inaccessible.
STEP 04
Server Validation
Bank's server compares the signed hash to the incoming request. It detects a Mathematical Mismatch with the hacker's data.
STEP 05
Outcome: Trust
The transaction is Automatically Blocked. The bank has immutable evidence that the hardware signature did not match the request.
