A comprehensive Python library for generating unique, hardware-based device fingerprints that work consistently across sessions and system changes.

## What This Library Does

Think of this library as a way to create a "digital DNA" for any computer or device. Just like how your fingerprint uniquely identifies you, this library creates a unique identifier for devices based on their hardware characteristics. It's particularly useful for:

- **Security applications** - Detecting when someone tries to access your system from an unknown device
- **License management** - Ensuring software runs only on authorized machines
- **Fraud prevention** - Identifying suspicious login attempts from new devices
- **Analytics** - Tracking unique devices without collecting personal information

## System Architecture Overview

Here's how the device fingerprinting system works at a high level:

        Gen->>Stor: Get storage fingerprint
        Gen->>Net: Get network fingerprint
        Gen->>Sys: Get system fingerprint
    end
    
    CPU-->>Gen: CPU component hash
    Mem-->>Gen: Memory component hash
    Stor-->>Gen: Storage component hash
    Net-->>Gen: Network component hash
    Sys-->>Gen: System component hash
    
    Gen->>Gen: Validate all components
    Gen->>Gen: Apply component weights (CPU 30%, Storage 25%, Network 20%, Memory 15%, System 10%)
    
    Gen->>Hash: Combine weighted components
    Hash->>Hash: SHA-256 final hash
    Hash->>Hash: Encode to readable format
    Hash-->>Gen: Final device fingerprint
    
    Gen-->>App: Unique device ID
    
    Note over Gen,Hash: Final fingerprint is deterministic - Same hardware equals Same fingerprint, Different hardware equals Different fingerprint
```

## Installation and Quick Start

### Installation

```bash
pip install device-fingerprinting-pro
```

Or from source:
```bash
git clone https://github.com/Johnsonajibi/DeviceFingerprinting.git
cd DeviceFingerprinting
pip install -r requirements.txt
```

### Basic Usage

```python
from device_fingerprinting import DeviceFingerprint

# Create a device fingerprint
fingerprint = DeviceFingerprint()
device_id = fingerprint.generate()

print(f"Device ID: {device_id}")
# Output: Device ID: 2a4b8c9d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b
```

### Advanced Usage with Component Details

```python
from device_fingerprinting import DeviceFingerprint

# Create fingerprint with detailed information
fingerprint = DeviceFingerprint()

# Generate with component breakdown
result = fingerprint.generate_detailed()

print(f"Device ID: {result['device_id']}")
print(f"CPU Component: {result['components']['cpu']}")
print(f"Memory Component: {result['components']['memory']}")
print(f"Storage Component: {result['components']['storage']}")
print(f"Network Component: {result['components']['network']}")
print(f"Confidence Score: {result['confidence_score']}")
```

### Device Comparison and Validation

```python
from device_fingerprinting import DeviceFingerprint

fingerprint = DeviceFingerprint()

# Store the device ID for later comparison
stored_device_id = fingerprint.generate()

# Later, verify if this is the same device
current_device_id = fingerprint.generate()

if stored_device_id == current_device_id:
    print("Same device confirmed")
else:
    print("Different device detected")
    
# Check similarity score for partial hardware changes
similarity = fingerprint.compare_devices(stored_device_id, current_device_id)
print(f"Device similarity: {similarity:.2%}")
```

## Security and Privacy Considerations

### What Information is Collected

The library collects only hardware-specific information:

- **CPU**: Model, cores, architecture (no usage data)
- **Memory**: Total capacity, configuration (no content)
- **Storage**: Device serials, models (no file data)
- **Network**: MAC addresses of physical adapters (no traffic)
- **System**: OS type, version (no personal files)

### What Information is NOT Collected

- Personal files or documents
- Network traffic or browsing history
- User accounts or passwords
- Application usage or installed software
- Geographic location
- Any personally identifiable information

### Data Processing

All collected hardware information is:
1. **Hashed immediately** using SHA-256
2. **Combined securely** with weighted algorithms
3. **Stored as hash only** - original data is discarded
4. **Non-reversible** - cannot reconstruct original hardware info

## Technical Specifications

### Hardware Detection Methods by Platform

| Component | Windows | macOS | Linux |
|-----------|---------|-------|-------|
| CPU | WMI, Registry | sysctl, system_profiler | /proc/cpuinfo, lscpu |
| Memory | WMI, GetPhysicallyInstalledSystemMemory | sysctl, system_profiler | /proc/meminfo, dmidecode |
| Storage | WMI, diskpart | diskutil, system_profiler | lsblk, /proc/partitions |
| Network | WMI, ipconfig | ifconfig, system_profiler | ip addr, /sys/class/net |
| System | Registry, WMI | sw_vers, uname | /etc/os-release, uname |

### Fingerprint Composition Weights

The final device fingerprint uses weighted components to ensure stability:

- **CPU Information**: 30% (highly stable)
- **Storage Devices**: 25% (moderately stable)
- **Network Interfaces**: 20% (stable for built-in adapters)
- **Memory Configuration**: 15% (changes with upgrades)
- **System Information**: 10% (may change with OS updates)

### Stability Across System Changes

| Change Type | Fingerprint Impact | Notes |
|-------------|-------------------|-------|
| Software installation | No change | Only hardware is fingerprinted |
| OS updates | Minimal change | System component weight is low |
| Driver updates | No change | Hardware IDs remain same |
| RAM upgrade | Moderate change | Memory component affected |
| Storage addition | Moderate change | New storage device detected |
| Network card replacement | Moderate change | Network component affected |
| CPU/Motherboard replacement | Major change | New device fingerprint |

## Requirements
