    elif risk_level == "medium":
        method = FingerprintMethod.ADVANCED
    else:  # high risk
        method = FingerprintMethod.QUANTUM_RESISTANT
    
    try:
        result = fingerprinter.generate_fingerprint(method)
        return result
    except FingerprintGenerationError as e:
        # Handle fingerprinting failures based on security policy
        if risk_level == "high":
            raise  # Don't allow fallback for high-risk scenarios
        else:
            # Allow fallback for lower risk scenarios
            return fingerprinter.generate_fingerprint_with_fallback(
                method, allow_fallback=True
            )

# Usage with different risk levels
low_risk_fp = adaptive_fingerprinting("low")
high_risk_fp = adaptive_fingerprinting("high")
```

### Enterprise Integration Pattern

```python
import logging
from datetime import datetime
from devicefingerprint import AdvancedDeviceFingerprinter, FingerprintMethod

class EnterpriseDeviceManager:
    def __init__(self):
        self.fingerprinter = AdvancedDeviceFingerprinter()
        self.logger = logging.getLogger(__name__)
    
    def register_device(self, user_id: str) -> dict:
        """Register a new device for enterprise user"""
        try:
            result = self.fingerprinter.generate_fingerprint(
                FingerprintMethod.QUANTUM_RESISTANT
            )
            
            device_record = {
                "device_id": result.fingerprint,
                "user_id": user_id,
                "registered_at": datetime.utcnow().isoformat(),
                "confidence": result.confidence,
                "components": result.components,
                "warnings": result.warnings
            }
            
            self.logger.info(f"Device registered for user {user_id}")
            return device_record
            
        except Exception as e:
            self.logger.error(f"Device registration failed: {e}")
            raise
    
    def verify_device_access(self, user_id: str, stored_device_id: str) -> bool:
        """Verify device access for enterprise security"""
        try:
            current_result = self.fingerprinter.generate_fingerprint(
                FingerprintMethod.QUANTUM_RESISTANT
            )
            
            # Implement secure comparison
            is_match = stored_device_id == current_result.fingerprint
            
            if is_match:
                self.logger.info(f"Device verification successful for {user_id}")
            else:
                self.logger.warning(f"Device mismatch detected for {user_id}")
            
            return is_match
            
        except Exception as e:
            self.logger.error(f"Device verification error: {e}")
            return False

# Enterprise usage
device_manager = EnterpriseDeviceManager()
device_record = device_manager.register_device("employee@company.com")
is_authorized = device_manager.verify_device_access(
    "employee@company.com", 
    device_record["device_id"]
)
```

## Security Considerations

### Threat Model

DeviceFingerprint is designed to protect against:

- **Token Theft**: Prevents stolen authentication tokens from being used on different devices
- **Session Hijacking**: Detects when sessions are transferred between devices
- **Account Takeover**: Identifies suspicious device changes in user accounts
- **Fraud Detection**: Flags transactions from unrecognized devices

### Security Limitations

**Important**: Device fingerprinting should be part of a comprehensive security strategy:

- **Not a Replacement for Authentication**: Device fingerprints complement, but don't replace, user authentication
- **Privacy Considerations**: Consider user privacy laws and disclosure requirements in your jurisdiction
- **Hardware Changes**: Legitimate hardware upgrades will change device fingerprints
- **VM and Container Limitations**: Virtualized environments may have reduced fingerprint stability

### Best Practices

1. **Use Appropriate Confidence Levels**: Match fingerprinting method to your security requirements
2. **Implement Graceful Degradation**: Handle fingerprinting failures appropriately
3. **Monitor for Changes**: Log and alert on unexpected device fingerprint changes
4. **Combine with Other Factors**: Use device fingerprinting as part of multi-factor authentication
5. **Regular Updates**: Keep the library updated for the latest security improvements

## API Reference

### Core Classes

The primary class for advanced device fingerprinting operations.

```python
class AdvancedDeviceFingerprinter:
    def generate_fingerprint(
        self, 
        method: FingerprintMethod = FingerprintMethod.QUANTUM_RESISTANT
    ) -> FingerprintResult:
        """Generate device fingerprint using specified method"""
    
    def generate_fingerprint_with_fallback(
        self,
        preferred_method: FingerprintMethod,
        allow_fallback: bool = False
    ) -> FingerprintResult:
        """Generate fingerprint with explicit fallback control"""
```

#### `FingerprintMethod` (Enum)

Available fingerprinting methods with different security levels:

- `BASIC`: Fast operation, moderate security (confidence: 0.7)
- `ADVANCED`: Balanced performance and security (confidence: 0.9)

#### `FingerprintResult` (Dataclass)

Result object containing fingerprint and metadata:

```python
@dataclass
class FingerprintResult:
    fingerprint: str          # The generated fingerprint
    method: FingerprintMethod # Method used for generation
    components: List[str]     # Hardware components analyzed
    timestamp: str           # Generation timestamp
    confidence: float        # Confidence score (0.0-1.0)
    warnings: List[str]      # Any warnings encountered
```

### Core Functions

#### `generate_device_fingerprint() -> str`

Legacy compatibility function that generates a quantum-resistant device fingerprint.

#### `bind_token_to_device(token_data: Dict[str, Any]) -> Dict[str, Any]`

Binds a security token to the current device by adding device fingerprint metadata.

#### `verify_device_binding(token_data: Dict[str, Any]) -> bool`

Verifies that a bound token is being used on the correct device.

### Exception Classes

#### `FingerprintGenerationError`

Raised when fingerprint generation fails and fallback is not appropriate for the security context.

**Token Theft**: Prevents stolen authentication tokens from being used on different devices\r\n- **Session Hijacking**: Detects when sessions are transferred between devices\r\n- **Account Takeover**: Identifies suspicious device changes in user accounts\r\n- **Fraud Detection**: Flags transactions from unrecognized devices\r\n\r\n### Security Limitations\r\n\r\n**Important**: Device fingerprinting should be part of a comprehensive security strategy:\r\n\r\n- **Not a Replacement for Authentication**: Device fingerprints complement, but don't replace, user authentication\r\n- **Privacy Considerations**: Consider user privacy laws and disclosure requirements in your jurisdiction\r\n- **Hardware Changes**: Legitimate hardware upgrades will change device fingerprints\r\n- **VM and Container Limitations**: Virtualized environments may have reduced fingerprint stability\r\n\r\n### Best Practices\r\n\r\n1. **Use Appropriate Confidence Levels**: Match fingerprinting method to your security requirements\r\n2. **Implement Graceful Degradation**: Handle fingerprinting failures appropriately\r\n3. **Monitor for Changes**: Log and alert on unexpected device fingerprint changes\r\n4. **Combine with Other Factors**: Use device fingerprinting as part of multi-factor authentication\r\n5. **Regular Updates**: Keep the library updated for the latest security improvements\r\n\r\n## API Reference\r\n\r\n### Core Classes\r\n\r\n#### `AdvancedDeviceFingerprinter`\r\n\r\nThe primary class for advanced device fingerprinting operations.\r\n\r\n```python\r\nclass AdvancedDeviceFingerprinter:\r\n    def generate_fingerprint(\r\n        self, \r\n        method: FingerprintMethod = FingerprintMethod.QUANTUM_RESISTANT\r\n    ) -> FingerprintResult:\r\n        \"\"\"Generate device fingerprint using specified method\"\"\"\r\n    \r\n    def generate_fingerprint_with_fallback(\r\n        self,\r\n        preferred_method: FingerprintMethod,\r\n        allow_fallback: bool = False\r\n    ) -> FingerprintResult:\r\n        \"\"\"Generate fingerprint with explicit fallback control\"\"\"\r\n```\r\n\r\n#### `FingerprintMethod` (Enum)\r\n\r\nAvailable fingerprinting methods with different security levels:\r\n\r\n- `BASIC`: Fast operation, moderate security (confidence: 0.7)\r\n- `ADVANCED`: Balanced performance and security (confidence: 0.9)\r\n- `QUANTUM_RESISTANT`: Maximum security, quantum-resistant (confidence: 0.95)\r\n\r\n#### `FingerprintResult` (Dataclass)\r\n\r\nResult object containing fingerprint and metadata:\r\n\r\n```python\r\n@dataclass\r\nclass FingerprintResult:\r\n    fingerprint: str          # The generated fingerprint\r\n    method: FingerprintMethod # Method used for generation\r\n    components: List[str]     # Hardware components analyzed\r\n    timestamp: str           # Generation timestamp\r\n    confidence: float        # Confidence score (0.0-1.0)\r\n    warnings: List[str]      # Any warnings encountered\r\n```\r\n\r\n### Core Functions\r\n\r\n#### `generate_device_fingerprint() -> str`\r\n\r\nLegacy compatibility function that generates a quantum-resistant device fingerprint.\r\n\r\n#### `bind_token_to_device(token_data: Dict[str, Any]) -> Dict[str, Any]`\r\n\r\nBinds a security token to the current device by adding device fingerprint metadata.\r\n\r\n#### `verify_device_binding(token_data: Dict[str, Any]) -> bool`\r\n\r\nVerifies that a bound token is being used on the correct device.\r\n\r\n### Exception Classes\r\n\r\n#### `FingerprintGenerationError`\r\n\r\nRaised when fingerprint generation fails and fallback is not appropriate for the security context.\r\n\r\n## Platform Support\r\n\r\n### Hardware Detection Capabilities\r\n\r\n| Platform | CPU Info | Memory | Storage | Network | System ID |\r\n|----------|----------|---------|---------|---------|-----------|\r\n| Windows  | \u2705       | \u2705      | \u2705      | \u2705      | \u2705        |\r\n| Linux    | \u2705       | \u2705      | \u2705      | \u2705      | \u2705        |\r\n| macOS    | \u2705       | \u2705      | \u2705      | \u2705      | \u2705        |\r\n\r\n### Platform-Specific Implementation Details\r\n\r\n#### Windows\r\n- Uses WMI (Windows Management Instrumentation) for hardware queries\r\n- Accesses Windows Registry for system identification\r\n- Supports both PowerShell and CMD environments\r\n\r\n#### Linux\r\n- Reads from `/proc/` filesystem for system information\r\n- Uses `/etc/machine-id` for system identification\r\n- Compatible with systemd and non-systemd distributions\r\n\r\n#### macOS\r\n- Utilizes system_profiler for hardware detection\r\n- Accesses IOKit framework data through system tools\r\n- Compatible with both Intel and Apple Silicon Macs\r\n\r\n## Performance Benchmarks\r\n\r\n### Typical Performance Metrics\r\n\r\n| Method | Average Time | Memory Usage | Components Analyzed |\r\n|--------|-------------|--------------|-------------------|\r\n| Basic | ~50ms | <1MB | 4-5 |\r\n| Advanced | ~150ms | <2MB | 6-8 |\r\n| Quantum-Resistant | ~200ms | <3MB | 8-10 |\r\n\r\n*Benchmarks measured on modern hardware (Intel i7, 16GB RAM, SSD storage)*\r\n\r\n### Optimization Tips\r\n\r\n- **Cache Results**: Fingerprints are stable; cache them to avoid repeated computation\r\n- **Choose Appropriate Method**: Use Basic method for non-critical applications\r\n- **Batch Processing**: Generate multiple fingerprints in sequence for better performance\r\n- **Async Integration**: Use asyncio wrappers for non-blocking operations in async applications\r\n\r\n## Contributing\r\n\r\nWe welcome contributions to DeviceFingerprint!
