Linux Hello is a Windows Hello-equivalent biometric authentication system for Linux. It provides secure facial authentication using IR cameras and TPM2-backed credential storage.
|
||||
|
||||
**Current Status**: Phase 3 (Security Hardening) complete. Uses placeholder algorithms for face detection/embedding until ONNX model integration (waiting for `ort` 2.0 stable).
|
||||
**Current Status**: All phases complete (1-5). Feature complete with ONNX model support.

```
|
||||

|

Settings App → D-Bus → linux-hello-daemon → Camera/TPM

|

- `#[cfg(target_os = "linux")]` - Real V4L2 implementation
|
||||
- `#[cfg(not(target_os = "linux"))]` - Mock implementation for development

ONNX code is feature-gated:

## Security Considerations
|
||||
|
||||
- `SecureEmbedding` and `SecureBytes` auto-zeroize on drop
|
||||
- Use `zeroize` crate for sensitive data
|
||||
- Constant-time comparisons for template matching (timing attack resistance)
|
||||
- Memory locking prevents swapping sensitive data
|
||||
- Software TPM fallback is NOT cryptographically secure (dev only)
|
||||
- **Encryption**: AES-256-GCM with PBKDF2-HMAC-SHA256 (600k iterations)
|
||||
- **Secure memory**: `SecureEmbedding` and `SecureBytes` auto-zeroize on drop
|
||||
- **Constant-time**: Template comparisons use `subtle` crate (timing attack resistant)
|
||||
- **Memory locking**: Sensitive data locked in RAM (no swap)
|
||||
- **IPC security**: Peer credentials (SO_PEERCRED), rate limiting, authorization
|
||||
- **Software TPM fallback**: Cryptographically strong but not hardware-bound

## Step 5: What to Expect
|
||||
## Step 5: ONNX Model Setup (For Real Face Recognition)
|
||||
|
||||
### With Placeholder Algorithms
|
||||
For accurate face recognition, you need ONNX models:
|
||||
|
||||
**Face Detection:**
|
||||
- Very basic - just checks image brightness/contrast
|
||||
- Assumes face is centered if image has "reasonable" contrast
|
||||
- **Not reliable** - may detect faces where there aren't any, or miss real faces
|
||||
### 5.1 Check System Requirements
|
||||
|
||||
**Face Recognition:**
|
||||
- Uses image statistics (mean, variance, histogram)
|
||||
- **Cannot reliably distinguish between different people**
|
||||
- May authenticate the wrong person
|
||||
- May reject the correct person
|
||||
ONNX support requires **glibc 2.38+**:
|
||||
- Ubuntu 24.04 or later
|
||||
- Fedora 39 or later
|
||||
- Arch Linux (rolling release)
|
||||
|
||||
**Anti-Spoofing:**
|
||||
- Framework is implemented
|
||||
- But depends on accurate face detection (which we don't have)
|
||||
- **Will not effectively prevent photo/video attacks**
|
||||
```bash
|
||||
# Check your glibc version
|
||||
ldd --version
|
||||
```
|
||||
|
||||
### Expected Behavior
|
||||
### 5.2 Download Models
|
||||
|
||||
✅ **Will work:**
|
||||
- Camera enumeration
|
||||
- Frame capture
|
||||
- Template storage/retrieval
|
||||
- CLI commands
|
||||
- Daemon communication
|
||||
- Basic workflow
|
||||

### ONNX Linking Errors
|

|

If you see errors about `__isoc23_strtoll`:
|

- Your system has glibc < 2.38
|
||||
- Use the default build (without `--features onnx`)
|
||||
- Or upgrade to Ubuntu 24.04+ / Fedora 39+

## Next Steps
|

|

Once you've tested the basic functionality:
|
||||
|
||||
1. **Wait for ONNX models** - Real face recognition requires ML models
|
||||
2. **Get TPM2 hardware** - For secure template storage
|
||||
3. **Security audit** - Before production use
|
||||
4. **Contribute** - Help improve the project!
|
||||
5. **Use TPM for production** - Software fallback is for development only

## What Works With/Without ONNX
|
||||
|
||||
### Default Build (No ONNX)
|
||||
- All infrastructure and security features
|
||||
- Camera capture and IR control
|
||||
- Anti-spoofing framework
|
||||
- Template encryption (AES-256-GCM)
|
||||
- IPC and D-Bus communication
|
||||
- **Placeholder** face detection/embedding (not accurate)
|
||||
|
||||
### With ONNX Models
|
||||
- Accurate face detection (RetinaFace)
|
||||
- Accurate face embedding (MobileFaceNet)
|
||||
- Production-ready face recognition
|
||||
- Proper anti-spoofing based on real face data
|
||||
|
||||
---
|
||||
|
||||
**The system is feature-complete.** For production use, build with `--features onnx` on a compatible system and download the ONNX models.

|
||||
|
||||
**ONNX support requires glibc 2.38+:**
|
||||
- Ubuntu 24.04 or later
|
||||
- Fedora 39 or later
|
||||
- Arch Linux (rolling release)
|

```
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# 1. Download models (see instructions below)
|
||||
# 2. Place in this directory:
|
||||
# models/retinaface.onnx
|
||||
# models/mobilefacenet.onnx
|
||||
|
||||
# 3. Build with ONNX support
|
||||
cargo build --release --features onnx
|
||||
|
||||
# 4. Test
