How to stop a document being forwarded

Lock it to one device, and forwarding the link achieves nothing.

The situation

A link is trivially forwardable, and most secure sharing tools treat anyone holding the link as the intended recipient.

FINIS can bind a document to the first device that opens it. Anyone else following the same link is refused, and the sender sees that it happened.

As you send the document.

The document binds to their device.

Other devices are refused, and the attempt is logged.

The link works for the person you sent it to — and for nobody they forward it to.

Recipients, devices, lifetime, watermarking and access — all decided by the sender, all changeable afterwards.

Every open, every recipient, every timestamp — in one history you can show to someone else.

What if they genuinely change device?

The sender can release the lock.

Can I combine it with expiry?

Yes — device lock, expiry and watermarking work together.
