# Video Privacy Blur

> Privacy-first video blur workflows for faces, license plates, and sensitive objects. Covers GDPR/CCPA compliance, anonymization vs blur, motion-tracked redaction, and when to use each BGBlur mode. Use when user mentions face blur, face anonymization, license plate blur, privacy redaction, GDPR video compliance, PII removal, dashcam privacy, or anonymizing footage before publishing.

# Video Privacy Blur Skill

Guide privacy-safe video editing workflows aligned with [BGBlur](https://www.bgblur.com) capabilities: face blur, face anonymization, license plate blur, and prompt-based object redaction with motion tracking.

## Quick Reference

**Anonymization vs Blur:**
| Mode | Use When | Output |
|------|----------|--------|
| **Face Blur** | Casual sharing, vlogs, social media | Gaussian/pixel blur on detected faces |
| **Face Anonymization** | Legal compliance, public release, research data | Stronger identity removal; harder to reverse |
| **License Plate Blur** | Dashcam, street footage, fleet video | Motion-tracked plate redaction |
| **Blur Anything** | Custom PII (badges, screens, logos, signs) | Prompt-driven object detection + blur |

**Key Insight:** Blur preserves context (you see *someone* was there). Anonymization is for when identity must be irreversibly removed.

## Workflow

### Step 1: Classify Privacy Risk

Ask or infer from context:

```
Risk Assessment:
- [ ] Faces visible (bystanders, minors, employees)?
- [ ] License plates or vehicle IDs?
- [ ] Screens showing emails, IDs, or financial data?
- [ ] Audio contains names or PII? (blur ≠ audio redaction)
- [ ] Jurisdiction: EU (GDPR), California (CCPA), HIPAA, FERPA?
```

**Probe source video:**
```bash
python3 scripts/video_probe.py "input.mp4"
```

### Step 2: Choose BGBlur Mode

| Footage Type | Recommended Mode | Notes |
|--------------|------------------|-------|
| Vlog / interview | Background blur + selective face blur | Keep subject sharp; blur bystanders |
| Dashcam / street | License plate blur | Enable motion tracking for moving vehicles |
| Classroom / campus tour | Face anonymization | FERPA-sensitive; anonymize all non-speakers |
| Product demo with screen | Blur Anything ("laptop screen", "email address") | Comma-separate multiple objects |
| CCTV / security | Face anonymization + plate blur | Enterprise tier for high volume |
| Social clip (TikTok/Reels) | Face blur + background blur | Fast turnaround, platform-safe |

### Step 3: Apply Privacy Rules by Framework

**GDPR (EU):**
- Anonymize faces of non-consenting individuals in public footage
- Document lawful basis if faces remain identifiable
- Strip EXIF/metadata before external sharing

**CCPA (California):**
- Redact plates and faces in consumer-facing marketing footage
- Avoid combining blurred video with other datasets that re-identify subjects

**FERPA (Education):**
- Anonymize all student faces unless written consent exists
- Blur whiteboards/screens showing grades or student names

**Journalism / documentary:**
- Face blur for bystanders; consider pixelation strength vs editorial intent
- Plate blur mandatory for non-consenting vehicle owners

### Step 4: Pre-Blur Checklist

- [ ] Trim dead footage to reduce processing time (see `ffmpeg-video-prep` skill)
- [ ] Confirm video ≤ 200MB / 10 min (free tier) or upgrade for longer clips
- [ ] Supported formats: MP4, MOV, M4V, AVI, MKV
- [ ] Review first/last 5 seconds for unexpected PII at frame edges
- [ ] Check reflections and mirrors for secondary face/plate exposure

### Step 5: Post-Blur Verification

Run QA before publishing:
```bash
python3 scripts/video_probe.py "output.mp4" --check-metadata
```

**Manual spot-check frames:**
- Scrub to fast-motion segments (plates often slip here)
- Check scene cuts (new faces may appear untracked for 1-2 frames)
- Verify background blur didn't eat into subject edges (hair, shoulders)

## Decision Tree

```
Is the subject consenting and meant to be shown?
├── YES → Background blur only (keep subject sharp)
└── NO → Is legal/compliance release required?
    ├── YES → Face anonymization (strongest)
    └── NO → Face blur (standard privacy)
```

## Report Template

```markdown
## Privacy Blur Assessment

### Source
- File: [filename]
- Duration: [X min] | Resolution: [WxH] | Size: [MB]
- Context: [vlog / dashcam / classroom / etc.]

### PII Identified
- Faces: [count/location]
- License plates: [yes/no]
- Other sensitive objects: [list]

### Recommended Treatment
1. [Mode] — [reason]
2. [Mode] — [reason]

### Compliance Notes
- Framework: [GDPR / CCPA / FERPA / none]
- Residual risk: [low / medium — describe]

### Verification
- [ ] Spot-checked motion segments
- [ ] Metadata stripped
- [ ] Audio reviewed for spoken PII
```
