# Deepgram Data Handling

## Overview
Best practices for handling audio data and transcriptions with Deepgram, including storage, retention, and compliance.

## Prerequisites
- Understanding of data protection regulations
- Cloud storage configured
- Encryption capabilities
- Data retention policies defined

## Data Lifecycle

```
Upload → Process → Store → Retain → Archive → Delete
  ↓         ↓        ↓        ↓         ↓        ↓
Encrypt  Transcribe  Save   Review   Compress  Secure
                                               Delete
```

## Compliance Considerations

| Regulation | Key Requirements |
|------------|------------------|
| GDPR | Data minimization, right to deletion, consent |
| HIPAA | PHI protection, access controls, audit logs |
| SOC 2 | Security controls, availability, confidentiality |
| PCI DSS | Data encryption, access logging |

## Instructions

### Step 1: Implement Secure Upload
Handle audio uploads with encryption and validation.

### Step 2: Configure Data Processing
Process transcriptions with privacy controls.

### Step 3: Set Up Storage
Store data with appropriate encryption and access controls.

### Step 4: Implement Retention
Automate data retention and deletion policies.

## Examples

### Secure Upload Handler
```typescript
// services/secure-upload.ts
import crypto from 'crypto';
import { S3Client, PutObjectCommand } from '@aws-sdk/client-s3';
import { KMSClient, GenerateDataKeyCommand } from '@aws-sdk/client-kms';

interface UploadOptions {
  userId: string;
  purpose: string;
  retentionDays: number;
  encrypted: boolean;
}

export class SecureAudioUpload {
  private s3: S3Client;
  private kms: KMSClient;
  private bucket: string;
  private kmsKeyId: string;

  constructor() {
    this.s3 = new S3Client({});
    this.kms = new KMSClient({});
    this.bucket = process.env.AUDIO_BUCKET!;
    this.kmsKeyId = process.env.KMS_KEY_ID!;
  }

  async upload(
    audioBuffer: Buffer,
    options: UploadOptions
  ): Promise<{ audioId:
