Verify a voice or video request
See this course’s project requirements
A media-verification packet with a claim map, provenance trail, cue log, independent-channel check, claim-specific verdicts, and a share-or-hold note.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Extract the event, place, time, and consequence claims.
- Trace the fictional media history and separate reposts from independent sources.
- Record cues with alternative explanations and detector limits.
- Verify the request through a separately established channel.
- Write claim-specific verdicts and a private sharing decision.
Review and revise
Use these criteria to check your work and choose what to improve.
- Observations remain separate from inferred causes.
- Source history and independent evidence are accurately traced.
- Verdicts distinguish contradicted claims from unknown production methods.
- The final action avoids unsupported claims and unnecessary amplification.

The idea in everyday life
Fictional voice message claims to be a club organizer: “The workshop moved. Send your member list to this new link now.” The club’s previously saved official page lists its organizer contact and says no member list is requested. A supplied independent reply from that saved contact says the message is unauthorized. No real messages or links are used.
A familiar face or voice does not authenticate a request.
Verify a voice or video request: guided practice
A familiar face or voice does not authenticate a request.
Use paper or a free local text editor. This is an original fictional practice case; do not submit its records to a real service. Start this lesson with these facts, even if an earlier variation changed them. Fictional voice message claims to be a club organizer: “The workshop moved. Send your member list to this new link now.” The club’s previously saved official page lists its organizer contact and says no member list is requested. A supplied independent reply from that saved contact says the message is unauthorized. No real messages or links are used.
1. Separate identity from request
Record who the message claims to be and what action it asks.
You should see: Claimed organizer; urgent member-list upload to a new link.
Identity and action both require verification.
2. Choose a known channel
Use the previously saved contact, not details included in the suspicious message.
You should see: Verification route: the saved official organizer contact.
An attacker can control contact details inside the message.
3. Apply the independent reply
Record the supplied organizer response without claiming a generation method.
You should see: Request unauthorized; whether the voice was synthetic is not established.
You can reject a request without proving how the media was made.
4. Draft a response plan
Write a local note to pause the upload and retain minimal relevant evidence.
You should see: Do not upload the list; preserve message ID/time and report through the established channel.
Protecting information does not require forwarding private member data.
What to finish
Verify a voice or video request record with the worked decisions and changed-case check.
Watch for this
Believing a familiar voice authenticates a request or assuming unauthorized means definitely AI-generated.
How can I tell I understand it?
Check a claimed speaker or request through an independent channel. Explain the evidence behind the result and correct any mismatch.
