Three Approaches to Evidence Preservation
When you need to preserve digital evidence, you have three main options:
- Self-service forensic capture (e.g., TrueSnap)
- Notarized screenshots (notary public witnesses your screen)
- Professional forensic firms (expert examination and testimony)
Each has its place. The right choice depends on your situation's urgency, stakes, and budget.
Quick Comparison
| Factor | TrueSnap | Notarization | Forensic Firm |
|---|---|---|---|
| Cost | $2-5 per capture | $50-200 per session | $200-500+/hour |
| Speed | Instant (seconds) | Need appointment | Days to weeks |
| Availability | 24/7, anywhere | Business hours | Business hours |
| Technical depth | High (hash, blockchain, HAR) | Low (visual only) | Very high |
| Expert testimony | No | Notary can testify | Expert witness available |
| Court acceptance | Growing | Well-established | Gold standard |
| Urgency handling | Excellent | Poor | Moderate |
TrueSnap (Self-Service Forensic Capture)
Best for:
- Time-sensitive situations — Content that might disappear within hours
- Frequent evidence needs — When you capture evidence regularly
- Budget-conscious cases — Small claims, documentation, compliance
- International evidence — Capturing content from any jurisdiction, any time
Strengths:
- Immediate capture without appointments
- Cryptographic proof (SHA-256 + blockchain)
- Complete technical package (HAR, DOM, TLS certs)
- Cost-effective for multiple captures
- No geographic limitations
Limitations:
- No expert witness for court testimony
- Relatively newer in courts (but gaining acceptance)
- Self-collected (may require explanation of methodology)
Typical cost: $2-5 per capture
Traditional Notarization
Best for:
- Established legal proceedings — When your attorney recommends it
- Simple visual evidence — When what's visible on screen is sufficient
- Conservative jurisdictions — Courts very familiar with notarization
Strengths:
- Long legal tradition of acceptance
- Notary can serve as a witness
- Well-understood by courts and attorneys
- Official seal adds perceived authority
Limitations:
- No technical verification — A notary verifies they saw the screen, not that the content wasn't manipulated
- Appointment required — Evidence may disappear before you can get one
- Business hours only — Harassment at 2 AM can't be notarized until morning
- Geographic constraints — Must find a local notary
- Limited documentation — Only captures what's visually displayed
Typical cost: $50-200 per session (plus travel time)
Professional Forensic Firms
Best for:
- High-stakes litigation — Cases worth millions
- Complex investigations — Requiring deep technical analysis
- Expert testimony needs — When the court needs an expert witness
- Contested evidence — When the opposing party will aggressively challenge
- Criminal cases — Where evidence standards are highest
Strengths:
- Expert witness available for court testimony
- Deepest technical analysis possible
- Established credibility with courts
- Can handle complex, multi-source investigations
- Chain of custody documentation to highest standards
Limitations:
- Expensive — $200-500+/hour for examiner time
- Slow — Engagement, scheduling, analysis takes days to weeks
- Overkill for simple cases — Not cost-effective for basic evidence preservation
- Not instant — Web content may disappear before engagement begins
Typical cost: $2,000-50,000+ per engagement
Decision Framework
Use TrueSnap when:
- ✅ You need to capture something NOW (before it disappears)
- ✅ Budget is a concern
- ✅ You need multiple captures over time
- ✅ The technical evidence package (hash, blockchain, HAR) is sufficient
- ✅ You're building a documentation file for potential future action
Use Notarization when:
- ✅ Your attorney specifically recommends it
- ✅ The evidence is stable (won't disappear overnight)
- ✅ Visual proof is sufficient
- ✅ You need a human witness on record
- ✅ You're in a jurisdiction that heavily favors notarized evidence
Use a Forensic Firm when:
- ✅ Stakes justify the cost ($50K+ at issue)
- ✅ You'll need expert testimony at trial
- ✅ The evidence is technically complex
- ✅ Opposing counsel will aggressively challenge authenticity
- ✅ Criminal prosecution is involved
Hybrid Approach (Recommended)
For most serious cases, the optimal strategy combines multiple methods:
- Immediate: Use TrueSnap to capture evidence before it disappears (minutes)
- If needed: Engage a forensic firm for deeper analysis using your preserved evidence as a starting point
- For trial: The forensic firm's expert can reference TrueSnap's blockchain-verified captures as part of their testimony
This hybrid approach ensures you never lose time-sensitive evidence while still having access to full forensic services when stakes demand it.
The Cost of Inaction
The most expensive choice is doing nothing:
- Evidence disappears permanently
- No legal recourse without proof
- Fraudsters, harassers, and infringers face no consequences
- Your word against theirs — with nothing to back it up
Whatever method you choose, preserving evidence quickly is always better than a perfect approach that comes too late.
