Listening Copy Comparison
Audio watermarking vs password-protected links
A password controls entry to a listening link. A recipient-specific forensic audio watermark places an identifier in delivered audio so a detectable copy can be associated with a delivery record. They can be used together: a password before listening, a watermark inside the audio.
By Listening Copy · Reviewed
| Question | Password | Recipient-specific audio watermark |
|---|---|---|
| Before listening | Requires the password | Does not gate access by itself |
| After audio leaves the player | Does not identify saved or recorded audio | May provide a detectable delivery identifier |
| Forwarded access | A forwarded password can be reused | Does not prevent forwarding |
| Proof of who leaked it | No | No, a delivery match is not proof of responsibility |
Use passwords to add an access step
Deliver the password separately when the material calls for it. Optional SMS delivery requires recipient consent and is a convenience. They can instead get the password directly from the sender.
Use watermarks when tracing matters
Create a separate watermarked copy for each recipient. Check a suspected leaked file through the audio tracing workflow. A match connects the audio to the delivery, not necessarily to the person responsible for copying it.
Layer controls for sensitive releases
Combine individual links, expiry, passwords, download settings and watermarking according to the release. Watermarking uses one credit per started 30 minutes of each file for each recipient.
A watermark can help identify the delivered copy from which a leak originated. It does not prove who leaked it, prevent recording, or guarantee detection after every edit. Revoking a link stops future access through that link; it cannot recall files already downloaded.
Common questions
Should I use both?
They can complement each other for sensitive material. Choose the extra steps according to the risk and the recipient's needs.
Will a password stop a leak after download?
No. It gates access, but cannot recall or identify a saved file.
