ICEYOU - Personal Anti-Intrusion Monitor

ICEYOU watches your Windows machine while you're away. The moment any input, USB event, or camera tamper happens after idle, it locks the screen behind a full-screen white overlay with a mandatory password / face-unlock gate, snaps a photo of whoever is at the keyboard, records what they typed, and emails you the evidence.

What It Does

Capability	Detail
Idle / away detection	Configurable idle timeout flips ICEYOU into "away" mode
Whiteout lockout	Full-screen overlay with embedded password + face unlock
Motion recording	Rolling 5s pre + event + 5s post AVI clips saved to motion_clips/ while locked
Escape-key blocking	Low-level Windows keyboard hook blocks CTRL+ESC, ALT+TAB, WIN, ALT+F4, CTRL+SHIFT+ESC, etc. while locked
Snapshot on attempt	Webcam photo for every unlock attempt (success or failure)
Credential logging	Failed password attempts saved to events.log and emailed
Face recognition unlock	LBPH-based owner verification with Unlock by Face button + auto-attempt
Camera tamper detection	Triggers full lockdown if lens is covered while locked
USB / device monitor	Drive insertions/removals during away are treated as intrusions
Email alerts	SMTP with photo attachment + entered credentials
OS workstation lock	After N failed password attempts, Windows lock kicks in (whiteout reappears on resume)
System tray UI	Pause/resume monitoring, force away, send test email, open snapshots/log
Hotkeys	Force away & re-show unlock prompt globally

Quick Start

1. Create a virtualenv (recommended — opencv-contrib requires numpy < 2):

   python -m venv .venv
   .\.venv\Scripts\Activate.ps1
   pip install -r requirements.txt
   

2. Copy & edit config:

   copy config.example.json config.json
   notepad config.json
   

   • Set unlock_password to your phrase.
   • Fill SMTP details (Gmail App Password recommended).
   • Pick the correct camera_device_index (run python face_enrollment.py --list-cameras to enumerate).

3. (Optional) Enroll your face:

   python face_enrollment.py --name owner
   

   Re-run with the same --name for each accessory combination (glasses, headphones, hat) to build a robust model.

4. Run:

   python main.py
   

   A red shield tray icon appears. Right-click for the menu.

5. (Optional) Use the Add to Windows Startup option (via startup.py) so ICEYOU launches at login.

Hotkeys & Manual Control

Hotkey (default)	Action
Ctrl+Alt+L	Force away mode + show whiteout immediately
Ctrl+Alt+U	Re-show the whiteout password prompt (useful if it was hidden)
Ctrl+Alt+M	Toggle Monitoring — Pause or resume monitoring (motion + intrusion detection)
Ctrl+Alt+S	Stop Monitoring — Immediately pause motion recording and intrusion detection

Combos are configurable in config.json → hotkeys using pynput syntax (<ctrl>+<shift>+<alt>+p, etc.). Restart ICEYOU after editing.

Automatic behavior: When the user successfully unlocks the whiteout, monitoring is automatically paused (no more motion recording or intrusion detection). It will automatically resume the next time the machine idles for the configured timeout.

---

Tray Menu

Item	Description
Stop Monitoring	Immediately pauses motion recording, intrusion detection, and releases the camera
Resume Monitoring	Re-enables idle detection, motion recording, and intrusion triggers
Toggle Away Mode	Manual away on/off (away forces the whiteout)
Toggle White Screen	Disable the whiteout while still monitoring
Open Snapshots Folder	Browse all captured photos
View Motion Clips	Open motion_clips/ (post-auth in practice)
Open Log File	View events.log
Send Test Email	Sanity-check SMTP without triggering an intrusion
Settings	Opens config.json in Notepad (restart to apply)
Exit	Stops everything cleanly

Intrusion Response Flow

1. Detect — Idle ≥ idle_timeout_seconds (or you pressed Ctrl+Alt+L) → away mode + whiteout up.
2. Trigger — Any keyboard, mouse, USB, or camera-obscured event during away fires an intrusion:
   • Snapshot captured (saved to snapshots/)
   • intrusion_detected event logged
   • Email alert sent with photo
   • Whiteout stays up with the password / face-unlock prompt
3. Locked state — manual_lock is set; ordinary activity cannot clear away mode. Only a correct unlock does.
4. Password gate — Cannot be cancelled or closed. After max_unlock_attempts (default 3) wrong passwords, Windows workstation lock kicks in. When the user returns from the Windows lock screen the ICEYOU whiteout is still there — unlocking Windows alone is not enough.
5. Success — Whiteout dismisses, failure counter resets, auto-away is snoozed briefly so you can work.

---

Unlock Attempt Audit Trail

Every interaction with the unlock prompt is recorded:

• Snapshot of whoever is at the keyboard: snapshots/snapshot_<timestamp>_unlock_<success|fail>_<password|face>.jpg
• Structured log entry appended to events.log (one JSON object per line):
  • method — "password" or "face"
  • success — boolean
  • snapshot — path to the photo
  • entered — only on failed password attempts — the literal text the intruder typed
  • label, confidence — for face attempts
• Email alert (if email.enabled) with the snapshot attached:
  • Failed password attempts include the typed text in the body
  • Successful unlocks confirm but never include your real password
• Auto face attempts (every 4 s) are silent (no log / no email) to avoid flooding. Only manual Unlock by Face clicks and successful matches are recorded.

If alerts aren't arriving: tray → Send Test Email (or python test_email.py). SMTP errors land in events.log as email_failed. Gmail → external-domain alerts often hit Spam — check there first and mark "Not spam" to whitelist.

---

Face Recognition Unlock

Optional second unlock path next to the password.

1. Install the contrib OpenCV build (required for cv2.face):

   pip install --upgrade --force-reinstall opencv-contrib-python
   

2. Enroll your face — multi-pose, multi-look:

   python face_enrollment.py --name owner
   python face_enrollment.py --camera 1 --list-cameras
   

   The capture window cycles through 5 poses (straight, left, right, up, down). Controls:

   • Click the preview window — most reliable capture
   • SPACE / ENTER / C — capture (window must have focus)
   • Hold a steady face ≥ 2 s — auto-capture
   • R restart, Q / ESC quit

   Backend selection:

   • Default (--backend lbph): Trains the lightweight LBPH model (faces/model.yml).
   • DNN (--backend dnn): Trains a much more accurate FaceNet-style model using face_recognition (requires pip install face-recognition + build tools on Windows). Saves to faces/face_encodings.pkl.

   For glasses / headphones / hats, re-run with the same --name so the model learns all your looks under one identity.

3. Enable in config.json:

   "face_recognition_enabled": true,
   "face_unlock": {
     "enabled": true,
     "confidence_threshold": 85.0,
     "auto_attempt": true,
     "attempt_interval_seconds": 4.0,
     "frames_per_attempt": 4,
     "allowed_labels": ["owner"]
   }
   

   • confidence_threshold — lower = stricter (LBPH distance). 50 = very strong, 70 = balanced, 85 = lenient. Tune based on the conf=… value shown on misses.
   • allowed_labels — list of enrolled identities allowed to unlock. null = any enrolled label.
   • auto_attempt — background tries every attempt_interval_seconds while the whiteout is up.

While the whiteout is shown:

• Auto-attempts run silently every 4 s (default).
• The Unlock by Face button lets you trigger a manual attempt (this is logged + emailed; auto attempts are not).
• Face failures do not count toward the 3-strike OS-lock — only typed passwords do, so a bad camera angle can never lock you out.

Status hint: failed face attempts show Face not recognised (best=<label>, conf=<value>) on the whiteout. If you consistently see conf slightly above your threshold, either raise the threshold or enroll more samples.

---

Camera Tamper Detection

When the whiteout is active, ICEYOU periodically samples the camera (default every 12 s). If the frame mean brightness or pixel variance drops below thresholds (lens covered, sticker over webcam, etc.), it immediately triggers full lockdown — email alert + OS workstation lock — without waiting for input. Configure in config.json → camera_obscured_detection.

---

Motion Recording

While the whiteout is up, src/iceyou/motion_recorder.py continuously samples the webcam and keeps a rolling 5 s pre-buffer of frames. When motion is detected (frame differencing above sensitivity), it writes the buffered pre-roll + the event + 5 s of post-roll to motion_clips/motion_<timestamp>.avi (MJPG codec). Each finalized clip:

• Logs a motion_recorded line to events.log with the clip path.
• Pops a system-tray notification ("Motion event saved: motion_…avi").
• Does not trigger an email (snapshots + unlock attempts already cover that).

Recording starts on WhiteScreen.show() and stops on WhiteScreen.hide() — there is no recording when ICEYOU is not in the locked state.

Viewing clips post-authentication: the tray menu has a View Motion Clips item that opens the motion_clips/ folder in Explorer. While the whiteout is up the escape-key hook prevents the intruder from reaching the tray icon, so this item is effectively post-authentication. Once you unlock, right-click the tray icon and pick View Motion Clips to review.

Config (config.json → motion_recording):

"motion_recording": {
  "enabled": true,
  "clips_dir": "motion_clips",
  "fps": 15,
  "pre_seconds": 5.0,
  "post_seconds": 5.0,
  "sensitivity": 2500,       // min contour area in pixels; lower = more sensitive
  "cooldown_seconds": 8.0    // min gap between separate clips
}

---

Escape-Key Blocking

While the whiteout is shown, a low-level Windows keyboard hook (src/iceyou/keyboard_block.py) swallows:

• WIN (left + right)
• CTRL+ESC (Start menu)
• ALT+TAB, ALT+ESC (task switching)
• ALT+F4 (close window)
• ALT+SPACE (window menu)
• CTRL+SHIFT+ESC (Task Manager hotkey)

Disable with "block_escape_keys": false if needed (e.g. development). The hook is removed automatically on unlock.

Hard limits (Windows-enforced, cannot be intercepted from user mode):

• CTRL+ALT+DEL — Secure Attention Sequence is kernel-enforced. An intruder can still reach the security screen → Task Manager → kill python.exe.
• Hard power off, pulling the keyboard.
• Logging in as a different Windows user.

To harden against CTRL+ALT+DEL → Task Manager, run as Administrator and set the registry value HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr = 1 (DWORD). ICEYOU does not apply this automatically because it's a system-wide setting affecting every program.

Troubleshooting

Symptom	Fix
No tray icon	Make sure python main.py is running; check events.log for startup errors.
Email alerts not arriving	Check Spam folder. Use Send Test Email in tray (or python test_email.py). Look for email_failed in events.log.
Face unlock never matches	Status line shows conf=<value>. Either raise confidence_threshold in config.json or re-enroll with more samples / better lighting / same accessories you're wearing now.
Password field clears mid-typing	Already fixed — input while the whiteout is up is treated as challenge, not re-intrusion. Pull latest monitor.py + white_screen.py.
Tk error Tcl_AsyncDelete: async handler deleted by the wrong thread	Already fixed — WhiteScreen uses a persistent Tk root on a dedicated thread.
Tk error can't set fullscreen attribute… override-redirect flag is set	Already fixed — WhiteScreen sizes to screen via geometry() instead of -fullscreen.
numpy<2 conflict with opencv-contrib-python	Use the recommended .venv virtualenv.
Antivirus flags ICEYOU	Low-level keyboard hooks trigger heuristics. Whitelist the project folder.

Privacy & Use

ICEYOU accesses your camera, keyboard, mouse, and writes intruder photos + entered text to local disk and email. It is intended strictly for protecting your own machine. Do not use it for unauthorized surveillance of others.

---

Roadmap

• Encrypted at-rest storage of snapshots and log
• Optional cloud upload of evidence
• Windows service mode (run without an interactive session)
• Web dashboard for remote review
• DNN-based face recognition (FaceNet / dlib) for higher accuracy than LBPH
