Backend Verification Checks
🔍 Reference Lookup
Does CREF-73D9-221B exist in the database? If not, instruction is invalid and should be rejected immediately.
👤 Customer Identity
Which customer submitted this instruction? Confirms Sarah Mitchell is the correct client for this matter.
📱 Device Verification
Which device signed the instruction? Ensures it came from Sarah's registered device with valid passkey signature.
📁 Matter Context
For which matter was this instruction issued? Links instruction to correct property transaction.
📋 Instruction Type
What category of instruction? Bank details, document approval, authority to proceed, etc.
💾 Payload Data
What are the actual details? Full bank account information, document references, etc.
🔒 Tampering Check
Has the instruction been altered? Cryptographic signature proves integrity.
🔄 Supersession Check
Has this been replaced by a newer instruction? Ensures agent acts on latest information.
Cryptographic Proof
Why This Cannot Be Faked
Because the instruction was signed with Sarah's device-bound passkey, the backend has cryptographic proof of authenticity:
- The signature was generated using Sarah's private key stored in device hardware
- Only Sarah's biometric (Face ID/Touch ID) could trigger signature generation
- The signature is mathematically tied to the exact instruction payload
- Any modification to the data would invalidate the signature
- An attacker cannot forge or replay the signature
- The backend verifies the signature using Sarah's registered public key
