How WakeSign proves a signature
If a signature is ever questioned, you need to show who signed, that it was really them, and that the document has not changed since. Here is what WakeSign keeps for every document.
1. The link belongs to one person
- Each signer gets a private link sent to the email address, and the cell number if you add one, that you chose.
- The link locks to the first phone or computer that opens it. If it is forwarded, it will not open for the next person, and the sender is told.
- Links expire. A signer can ask for a fresh one, which goes only to the address on file.
2. The signer is checked
- You can require a one-time code sent by text or email before the document opens.
- Before signing, every signer agrees to do business electronically. That consent is recorded with its time.
3. Every step is recorded
- WakeSign records when the document was sent, opened, verified, agreed to and signed, with the IP address and device for each step.
- Each event is chained to the one before it with a SHA-256 hash, so an event cannot be edited or removed without breaking the chain.
- WakeSign notes the city, region and internet provider of each signature and flags a VPN, proxy, data center or overseas connection. A flag never blocks a signature. It tells you to look closer.
4. The finished document is sealed
- When everyone has signed, the PDF is sealed with a digital signature from Wake Tech LLC in the PAdES format, with a trusted RFC 3161 timestamp.
- Any change to the file after sealing breaks the seal, and standard PDF readers will show it.
- A Certificate of Completion is attached to the document with the signers, the verification used, and the full audit trail.
5. Anyone can check it
- Upload any WakeSign PDF at wakesign.com/verify to confirm it is the original, unchanged document. It is free and needs no account.
