# AI & Data Sovereignty

## 📌 한 줄 통찰 (The Karpathy Summary)
> **"매 data 의 owner 는 누구?"**. Individual / Org / National 의 3 layer. Big Tech AI 의 training data 의 hidden cost. **Federated learning + differential privacy + sovereign cloud** 의 modern technical answer.

## 📖 구조화된 지식 (Synthesized Content)

### 3 layer 의 sovereignty

#### 1. Individual sovereignty
- 매 user 의 own data.
- Right to know (어떤 data 의 어떤 use).
- Right to delete (GDPR).
- Right to object (Article 21).
- Right to portability.
- 매 AI training data 의 opt-in / opt-out.

#### 2. Organizational sovereignty
- 매 company 의 customer data.
- 매 IP / trade secret.
- 매 vendor 의 DPA (Data Processing Agreement).
- 매 sub-processor 의 list.
- 매 cloud provider 의 dependency.

#### 3. National sovereignty
- 매 citizen data 의 location.
- 매 geopolitical risk (foreign govt access).
- 매 strategic AI capability.
- 매 industrial policy.

### Major regulation
| Regulation | Region | Key |
|---|---|---|
| **GDPR** | EU | Individual rights + extraterritorial |
| **CCPA / CPRA** | California | Sale opt-out, sensitive data |
| **PIPL** | China | Strict cross-border transfer |
| **DPDPA** | India | 2023+ |
| **PIPEDA** | Canada | Federal privacy |
| **POPIA** | South Africa |  |
| **LGPD** | Brazil | GDPR-similar |
| **Korea PIPA** | Korea | Modeled on GDPR |

→ 매 country 가 different 의 fragmentation.

### Cross-border transfer 의 challenge
- **Schrems II** (EU 2020): US-EU Privacy Shield invalid → 매 transfer 의 SCC + assessment.
- **EU-US Data Privacy Framework** (2023): replacement.
- **China data export**: strict (CSL, DSL, PIPL).
- **Russia data localization** (2014+).

### Data colonialism critique
- 매 Big Tech (US) 의 global data collection.
- 매 Global South 의 data extractivism.
- 매 local context 의 underrepresented.
- 매 AI 의 Western perspective bias.

→ Couldry & Mejias 의 academic concept.

### Sovereign cloud
- 매 country / region 의 own infra.
- Examples:
  - **GAIA-X** (EU): federated cloud.
  - **Bleu** (France): MS Azure 의 French sovereign.
  - **S3NS** (France): Google Cloud sovereign.
  - **Confidential Computing** (Azure / GCP): hardware-isolated.
  - **AWS Sovereign Cloud** (EU 2024+).

→ 매 vendor 의 "sovereign" claim 의 verification 어려움.

### Sovereign AI capability
- 매 country 의 own LLM.
- Examples:
  - **France**: Mistral AI.
  - **Falcon** (UAE).
  - **Kosmos** (Korean LG AI Research).
  - **HyperCLOVA X** (Naver).
  - **Yi** / **Qwen** (China).
  - **NTT 의 tsuzumi** (Japan).
- Compute (GPU export control).
- 매 data (자국 corpus).
- 매 talent.

→ AI sovereignty 의 strategic priority.

### Privacy-preserving AI

#### Federated Learning
- 매 device / hospital 의 own data.
- 매 model update 의 share.
- Central server 의 aggregate.

```python
# Conceptual
import flwr as fl

class Client(fl.client.NumPyClient):
    def fit(self, params, config):
        model.set_weights(params)
        model.fit(local_data)
        return model.get_weights(), len(local_data), {}

# 매 hospital / phone 의 own data + collective learning.
```

#### Differential Privacy
- 매 query 의 noise 추가.
- 매 individual 의 contribution 의 privacy 보장.

```python
# Apple's iOS, Google's Chrome.
import numpy as np

def dp_mean(data, epsilon=1.0):
    sensitivity = (max(data) - min(data)) / len(data)
    noise = np.random.laplace(0, sensitivity / epsilon)
    return np.mean(data) + noise

# Aggregate stats with privacy guarantee.
```

#### Homomorphic encryption
- 매 encrypted data 의 compute.
- 결과 도 encrypted.
- Decrypt 후 result.
- Computational cost ↑.

#### Secure Multi-Party Computation (MPC)
- 매 party 의 own data + collective compute.
- Cryptographic.

#### Confidential computing
- Hardware enclave (Intel SGX, AMD SEV-SNP, AWS Nitro).
- 매 cloud 의 compute 의 protect.
- 매 government / sovereign 의 critical.

### 매 industry challenge

#### Healthcare
- 매 country 의 health data localization.

- Getty vs Stable Diffusion: image 의 watermark.
- 매 author / artist 의 copyright class action.

#### Opt-out mechanism
- robots.txt + AI bot identifier.
- ai.txt proposal.
- 매 publisher 의 opt-out (NYT, Reddit deal).

#### Right to be forgotten in training data
- GDPR 의 right to erasure.
- 매 trained model 의 unlearn 어려움 (active research).

### 매 organizational pattern

#### Data classification
- Public / Internal / Confidential / Restricted.
- 매 AI tool 의 access 의 매 level.

#### Data localization
- 매 customer 의 region 의 storage.
- 매 service 의 region 의 deploy.
- Cross-region 의 explicit replication.

#### Privacy by design
- 매 system 의 default privacy.
- Minimum data collection.
- Purpose limitation.
- Storage minimization.

### Future trend
- 매 country 의 AI sovereignty 의 push (chip, data, model).
- 매 tech bloc (US, EU, China, India) 의 fragmentation.
- 매 user 의 portable identity (Solid Pods, Web3 식).
- 매 personal AI (on-device).

## 💻 패턴 (Engineering)

### Region-aware data routing
```ts
class DataRouter {
  determineRegion(user: User): string {
    if (user.country === 'DE') return 'eu-central';
    if (user.country in EU_COUNTRIES) return 'eu-west';
    if (user.country === 'CN') return 'cn-north';
    if (user.country === 'IN') return 'ap-south';
    return 'us-east';
  }
  
  async store(data: any, user: User) {
    const region = this.determineRegion(user);
    const client = this.getClientFor(region);
    await client.put(data);
  }
}
```

### Differential privacy (Apple-style)
```python
def collect_with_dp(events, epsilon=1.0):
    """RAPPOR-style randomized response."""
    f = 0.5  # response prob
    p, q = 0.5, 0.5
    
    randomized = []
    for e in events:
        if random.random() < f:
            randomized.append(random.choice([0, 1]))   # noise
        else:
            randomized.append(e)
    
    return randomized

# Apple iOS / Google Chrome 가 사용.
```

### Federated learning
```python
import flwr as fl

# Server
def server_strategy():
    return fl.server.strategy.FedAvg(
        fraction_fit=0.5,
        min_available_clients=10,
    )

fl.server.start_server(server_address='[::]:8080', strategy=server_strategy())

# Client (per hospital)
class HospitalClient(fl.client.NumPyClient):
    def fit(self, parameters, config):
        self.model.set_weights(parameters)
        self.model.fit(self.local_x, self.local_y, epochs=1)
        return self.model.get_weights(), len(self.local_x), {}
    
    def evaluate(self, parameters, config):
        loss, acc = self.model.evaluate(self.test_x, self.test_y)
        return float(loss), len(self.test_x), {'accuracy': acc}

fl.client.start_numpy_client(server_address='central:8080', client=HospitalClient())
```

### Confidential computing (AWS Nitro)
```bash
# Nitro Enclave 의 isolated compute
nitro-cli build-enclave --docker-uri my-app:latest --output-file my.eif
nitro-cli run-enclave --eif-path my.eif --memory 2048 --cpu-count 2

# 매 enclave 의 isolated, attestable, host 의 access X.
```

### Data classification + DLP
```python
SENSITIVE_PATTERNS = [
    (r'\b\d{3}-\d{2}-\d{4}\b', 'SSN'),
    (r'\b4\d{12,15}\b', 'CreditCard'),
    (r'(?i)passport[:= ]+\w+', 'Passport'),
]

def classify(text: str) -> str:
    for pattern, label in SENSITIVE_PATTERNS:
        if re.search(pattern, text):
            return 'restricted'
    return 'internal'

# 매 prompt 의 매 outgoing 의 check.
```

### opt-out signaling (ai.txt / robots.txt)
```txt
# robots.txt
User-agent: GPTBot
Disallow: /

User-agent: Google-Extended
Disallow: /

User-agent: anthropic-ai
Disallow: /

User-agent: ClaudeBot
Disallow: /
```

→ 매 LLM 의 training 의 opt-out (compliance 의 vendor 의 의지 의존).

### Vendor DPA template (excerpt)
```markdown
## Data Processing Addendum

Vendor agrees:
1. Process Data only per Customer instructions.
2. NOT use Customer Data for AI training without explicit opt-in.
3. Maintain ISO 27001 / SOC 2 Type II.
4. Sub-processors listed at: vendor.com/subprocessors.
5. Data location: EU (Frankfurt + Dublin).
6. 30-day notification of new sub-processor.
7. Customer right to audit (60-day notice).
8. Data deletion within 30 days of contract end.
9. Breach notification within 72 hours.
```

### Region failover (data residency)
```yaml
# K8s region affinity
apiVersion: v1
kind: Service
metadata:
  name: my-app
  annotations:
    cloud.google.com/load-balancer-type: 'Internal'
spec:
  type: LoadBalancer
  selector:
    app: my-app
    region: eu-west   # EU traffic 의 EU pod 만.
```

### Audit log (sovereignty compliance)
```ts
async function auditDataAccess(user: User, data: any, action: string) {
  await db.auditLog.insert({
    userId: user.id,
    userRegion: user.region,
    dataLocation: data.region,
    action,
    timestamp: new Date(),
    crossBorder: user.region !== data.region,
  });
}
```

→ 매 cross-border access 의 visible.

## 🤔 의사결정 기준 (Decision Criteria)

| 상황 | 추천 |
|---|---|
| EU customer | EU storage + GDPR |
