>>Mechanism

As described in this page, at most three parties are sharing the same copy of an i-WAT ticket data (an approval message from the drawer constitutes the valid i-WAT ticket data, which is shared among the drawer, user and receiver).

This function utilizes that fact by having the valid data of i-WAT tickets sent from past traders, verifies the signatures on the tickets, and recovers the correct data by storing them again in the i-WAT book.

>>Preparation

Before starting the recovery sequence, please be sure that you have the valid public key of yourself with which you have signed the lost/damaged i-WAT tickets and the valid public keys of your trading partners. Also, be certain that signatures made with those keys are verifiable.

• If, for some reason, you have lost the data in your i-WAT book only, and if your PGP (GnuPG) data remains intact, then you can proceed.
• If your PGP (GnuPG) data has also been lost, you need to follow these steps:
  1. Generate a new key pair (reference).
  2. Rebuild the web of trust with your trading partners.
     • Import public keys of each other, confirm the fingerprints and sign the public keys (reference).
  3. Obtain a copy of your old public key from your trusted party, and import it to your key rings.

>>How to Use

1. Choose "Recover Lost/Broken..." from "i-WAT Ticket" menu of the i-WAT Book.
   • A window appears to confirm if you really want to recover lost/broken i-WAT tickets based on the information that currently online members of yours have in their databases.
   
2. Click on "Yes".
   • If there is a recoverable i-WAT ticket, a window appears for each of such a ticket to confirm if you want to recover it.
   
3. Click on "Recover".
