Security & Privacy ​

DeepSeek is committed to providing enterprise-grade security and privacy protection for all users and their data.

Overview ​

Our comprehensive security framework includes:

  • Data Protection: End-to-end encryption and secure data handling
  • Privacy by Design: Built-in privacy protections and controls
  • Compliance: Industry-standard certifications and regulations
  • Access Control: Robust authentication and authorization
  • Monitoring: Continuous security monitoring and threat detection

Data Security ​

Encryption ​

Data in Transit ​

  • TLS 1.3: All API communications use TLS 1.3 encryption
  • Certificate Pinning: Enhanced protection against man-in-the-middle attacks
  • Perfect Forward Secrecy: Each session uses unique encryption keys
  • HSTS: HTTP Strict Transport Security enforced

Data at Rest ​

  • AES-256: All stored data encrypted with AES-256 encryption
  • Key Management: Hardware Security Modules (HSMs) for key protection
  • Key Rotation: Automatic encryption key rotation
  • Zero-Knowledge: DeepSeek cannot access your encrypted data

Implementation Example ​

python
import ssl
import requests
from deepseek import DeepSeek

# SDK automatically handles secure connections
client = DeepSeek(
    api_key="your-api-key",
    # SSL verification is enabled by default
    verify_ssl=True
)

# Manual verification for custom implementations
session = requests.Session()
session.verify = True  # Verify SSL certificates
session.mount('https://', requests.adapters.HTTPAdapter(
    ssl_context=ssl.create_default_context()
))

Data Handling ​

Data Processing ​

  • Ephemeral Processing: Data processed in memory only
  • No Persistent Storage: User data not stored after processing
  • Secure Deletion: Immediate secure deletion after use
  • Isolated Processing: Each request processed in isolation

Data Retention ​

json
{
  "data_retention_policy": {
    "api_requests": {
      "logs": "30 days",
      "content": "not stored",
      "metadata": "90 days"
    },
    "user_accounts": {
      "profile_data": "until account deletion",
      "usage_analytics": "2 years (anonymized)",
      "billing_data": "7 years (legal requirement)"
    },
    "deletion_process": {
      "user_request": "within 30 days",
      "automatic": "per retention schedule",
      "verification": "cryptographic proof of deletion"
    }
  }
}

Privacy Protection ​

Privacy by Design ​

Core Principles ​

  1. Data Minimization: Collect only necessary data
  2. Purpose Limitation: Use data only for stated purposes
  3. Transparency: Clear data usage policies
  4. User Control: Users control their data
  5. Security by Default: Secure settings by default

Privacy Controls ​

python
# Privacy-enhanced API usage
response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": "Hello"}],
    # Privacy controls
    store=False,  # Don't store conversation
    metadata={
        "privacy_level": "high",
        "data_residency": "eu"  # EU data residency
    }
)

Data Anonymization ​

Automatic Anonymization ​

  • PII Detection: Automatic detection of personal information
  • Data Masking: Real-time masking of sensitive data
  • Pseudonymization: Replace identifiers with pseudonyms
  • Differential Privacy: Mathematical privacy guarantees

Example Implementation ​

python
from deepseek.privacy import PrivacyFilter

# Initialize privacy filter
privacy_filter = PrivacyFilter(
    detect_pii=True,
    mask_emails=True,
    mask_phone_numbers=True,
    mask_ssn=True
)

# Apply privacy filtering
filtered_content = privacy_filter.filter(user_input)

response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": filtered_content}]
)

Security Best Practices ​

For Developers ​

Secure Coding ​

python
# ✅ Good: Secure API key handling
import os
from deepseek import DeepSeek

api_key = os.getenv('DEEPSEEK_API_KEY')
client = DeepSeek(api_key=api_key)

# ❌ Bad: Hardcoded API key
# client = DeepSeek(api_key="sk-1234567890abcdef")

# ✅ Good: Input validation
def validate_input(user_input):
    if len(user_input) > 10000:
        raise ValueError("Input too long")
    
    # Remove potential injection attempts
    sanitized = user_input.replace('<script>', '').replace('</script>', '')
    return sanitized

# ✅ Good: Error handling without exposing sensitive info
try:
    response = client.chat.completions.create(...)
except Exception as e:
    # Log full error internally
    logger.error(f"API error: {e}")
    # Return generic error to user
    return {"error": "An error occurred processing your request"}

Rate Limiting ​

python
import time
from collections import defaultdict

class RateLimiter:
    def __init__(self, max_requests=100, time_window=60):
        self.max_requests = max_requests
        self.time_window = time_window
        self.requests = defaultdict(list)
    
    def is_allowed(self, user_id):
        now = time.time()
        user_requests = self.requests[user_id]
        
        # Remove old requests
        user_requests[:] = [req_time for req_time in user_requests 
                           if now - req_time < self.time_window]
        
        if len(user_requests) >= self.max_requests:
            return False
        
        user_requests.append(now)
        return True

# Usage
rate_limiter = RateLimiter(max_requests=100, time_window=60)

if not rate_limiter.is_allowed(user_id):
    return {"error": "Rate limit exceeded"}
