  languages: string[];
  sensitivity: 'low' | 'medium' | 'high' | 'maximum';
  categories: ContentCategory[];
  customRules?: FilterRule[];
  realTime: boolean;
}

interface AnalysisResult {
  threatLevel: 'safe' | 'low' | 'medium' | 'high' | 'critical';
  confidence: number; // 0-100
  flaggedContent: string[];
  categories: string[];
  action: 'allow' | 'warn' | 'block' | 'report';
  timestamp: number;
}
```

### 1.2 Image & Video Analysis

#### Implementation
```typescript
interface MediaAnalysisEngine {
  analyzeImage(imageData: Buffer | URL): Promise<MediaAnalysisResult>;
  analyzeVideo(videoData: Buffer | URL): Promise<MediaAnalysisResult>;
  analyzeFrame(frameData: Buffer, timestamp: number): Promise<FrameAnalysis>;
}

interface MediaAnalysisResult {

## 2. Privacy Infrastructure

### 2.1 Zero-Knowledge Architecture
- **End-to-End Encryption**: All data encrypted at rest and in transit
- **Anonymous Processing**: No PII stored during content analysis
- **Parental Control**: Explicit consent required for data collection
- **Data Minimization**: Only essential metadata retained

#### Privacy Specification
```typescript
interface PrivacyConfig {
  encryptionStandard: 'AES-256' | 'ChaCha20-Poly1305';
  dataRetention: number; // days, default: 0 (no retention)
  parentalConsent: boolean;
  anonymization: 'full' | 'pseudonymous';
  auditLogging: boolean;
}

interface DataProtection {
  encrypt(data: any): EncryptedData;
  decrypt(encryptedData: EncryptedData, key: string): any;
  anonymize(userData: UserData): AnonymousData;
  purge(userId: string): Promise<boolean>;
}
```

### 2.2 Compliance Framework
- **COPPA Compliance**: Children's Online Privacy Protection Act
- **GDPR-K**: Kid-specific privacy regulations
- **FERPA**: Family Educational Rights and Privacy Act
- **ISO 27001**: Information security management

  platform: 'web' | 'mobile' | 'gaming' | 'social';
  apiVersion: string;
  capabilities: IntegrationCapability[];
  realTimeMonitoring: boolean;
  offlineSupport: boolean;
}

interface IntegrationCapability {
  name: string;
  description: string;

```typescript
interface OnboardingFlow {
  steps: OnboardingStep[];
  currentStep: number;
  completed: boolean;
}

interface ChildProfile {
  id: string;
  age: number; // 3-17
  sensitivityLevel: 'low' | 'medium' | 'high' | 'maximum';
  allowedCategories: string[];
  blockedCategories: string[];
  approvedContacts: string[];
  screenTimeLimit?: number; // minutes per day
  bedtimeRestriction?: { start: string; end: string };
  customRules: ProfileRule[];
}
```

## 5. Monitoring Dashboard (Parent)
