- The crime is inside your head
- 2025 BCI adoption: 4.2 M implants (Neuralink v3, Synchron stentrode).
- Cognitive-firewall bypass observed: attacker injects “thought payload” via malicious SSVEP flicker in AR ad.
- Result: victim unwittingly authorises $2.4 M crypto transfer by imagining the password.
Charge sheet: “unlawful cognition access” – first felony under California Cognition Privacy Act (CPA 2024).
- Neural evidence = electro-chemical noise that self-erases
- BCI flushes raw ECoG after 200 ms to prevent tissue heating.
- Implant DRAM holds 3 s of 300 Hz data – then overwrites.
Forensic window: capture, hash, and attest cognition before the brain reboots itself.
- Architecture: “Cognitive Camera” stack
| Component | Location | Role |
|---|---|---|
| e-ink patch | scalp surface | SSVEP sensor (flicker 15–60 Hz) |
| BCI API hook | implanted MCU | traps “intention vector” |
| Quantum RNG | wristband | entangled seed for hash |
| Edge server | 5G edge | real-time cognition graph |
| Cold neuron | orbital vault | offline encrypted ECoG |
- Capturing the malicious thought-vector
SSVEP flicker at 31.4 Hz induces P300 wave at 400 ms.
BCI firmware modified to copy raw ECoG slice into MRAM buffer when flicker detected.
Buffer hashed every 50 ms → quantum-signed (Dilithium-3) → uplinked via Narrowband-IoT (900 MHz, <100 mW) – skull-safe power. - Cognitive-to-crypto correlation
Victim’s motor-imaginary password (specific μ-rhythm 8–12 Hz) appears exactly 200 ms after 31.4 Hz trigger.
Cross-correlation = 0.97 (p <0.001).
Transfer TX signed 1.2 s later with same motor-pattern hash → causal chain proven. - Quantum-entangled cognition time-stamp
Entangled photon pair generated in wristband diamond NV centre.
- One photon hashed with ECoG slice → superposition seed.
- Collapse detected only when hash complete → provable one-time time-stamp.
Court accepts seed as “non-spoofable clock” (People v. MaliciousFlicker, L.A. Super. Ct. 2025).
- Privacy shield: only hashes leave skull
Raw ECoG never transmitted – only 512-bit hash + entropy proof.
Complies with CPA 2024 §5(a): “No raw neural data shall cross the dura mater.” - KPIs that keep neuro-ethicists satisfied
| Metric | 2025 Target | 2023 Impossible |
|---|---|---|
| Cognition capture latency | ≤50 ms | N/A |
| Thought-to-action correlation | ≥0.95 | N/A |
| Quantum time-stamp drift | 0 ns | N/A |
| Raw data leakage | 0 bit | N/A |
| Court admissibility | 100 % (last 5) | 0 % |
- 60-day neuro-forensic rollout
Week 0-2: Implant
- Flash BCI firmware with malicious-flicker trigger.
- Implant wristband quantum chip; verify entanglement visibility >98 %.
Week 3-4: Edge
- Deploy 5G edge node; create “cognition-graph” Kafka topic.
- Train correlation model on victim’s own μ-rhythm (opt-in).
Week 5-6: Attack
- Run flicker attack in VR lab; capture hash chain.
- Notarise quantum time-stamp with external auditor.
Week 7-8: Legal
- Package hash + correlation + quantum proof.
- External neuro-lawyer attests CPA compliance.
- Cost & ROI (crypto-exchange, $500 M daily vol)
| Item | Cost | Benefit |
|---|---|---|
| BCI firmware mod | $25 k | — |
| Quantum wristband | $12 k | — |
| Edge node + audit | $18 k | — |
| Total CapEx | $55 k | — |
| Avoided theft loss | — | $48 M |
| Reputation insurance discount | — | $1.5 M |
| Net ROI first year | 900× | — |
- Exit criteria (screenshot for neuro-insurer)
✅ Cognition hash ≤50 ms latency verified
✅ Thought-to-action correlation ≥0.95 over 100 trials
✅ Zero raw neural data exfiltrated
✅ Quantum time-stamp collision probability <10⁻¹²
✅ External CPA-compliance opinion signed
- Ethical footnote
When a crime occurs inside someone’s electrocortical field, the murder weapon is a flicker of light. Hash the thought, seal the quantum seed, and let the defence argue with physics—your proof is already entangled with the universe.
