Required information
For each upload, you can add:
- Description: What the evidence shows (recommended)
- Category: Type classification (e.g., photo, message, document)
- Date: When the evidence was created (extracted automatically when available)
- Tags: Custom labels for organization
Evidence authentication
Every piece of evidence uploaded to Family Evidence is cryptographically authenticated to establish integrity and admissibility.
What happens on upload
- SHA-256 hash: A unique digital fingerprint is generated
- NTP timestamp: Server time is recorded from trusted time servers
- Metadata extraction: EXIF data, file properties preserved
- Audit log entry: Upload event recorded with user details
Understanding SHA-256 hashes
A SHA-256 hash is a 64-character code unique to your file. Even a single pixel change creates a completely different hash. This proves the file hasn't been altered since upload.
Authentication certificates
Each piece of evidence can generate a certificate of authenticity that includes:
- SHA-256 hash value
- NTP-verified upload timestamp
- Original filename and file size
- Uploader identity and device info
- Chain of custody summary
Organizing evidence
Keep your evidence organized for easy retrieval and professional exports.
Categories
Assign categories to classify evidence types:
- Photos: Images of incidents, conditions, people
- Screenshots: Text messages, social media, emails
- Videos: Recordings of incidents or conditions
- Audio: Voicemails, recordings
- Documents: Agreements, records, correspondence
- Financial: Bank statements, receipts, invoices
- Medical: Records, prescriptions, reports
- Other: Anything that doesn't fit above
Tags
Create custom tags for your workflow. Examples:

Filtering and searching
Find evidence quickly using:
- Search: By description, filename, or content
- Date range: Filter by evidence date or upload date
- Category/tag: Filter by classification
- Uploader: Filter by who uploaded
Chain of custody
Family Evidence maintains a complete, immutable chain of custody for every piece of evidence.
What's tracked
Every action is logged with:
- Timestamp: NTP-verified server time
- User: Who performed the action
- Action: What was done (upload, view, download, export)
- IP address: Network origin
- Device: Browser/app and operating system
Chain of custody events
| Event | Description |
|---|---|
| Uploaded | File added to the system |
| Viewed | Evidence opened or previewed |
| Downloaded | Original file downloaded |
| Exported | Included in an export packet |
| Metadata edited | Description or tags changed |
| Shared | Access granted to new user |
Evidence cannot be modified
Once uploaded, the original evidence file cannot be edited or replaced. This is essential for maintaining admissibility. You can update descriptions and metadata, but those changes are tracked separately.
Viewing chain of custody
- Open any piece of evidence
- Click the "Chain of custody" or "History" tab
