The Client's final step in updating the Local Hash Table is the creation of the Local Master Document Hash. This is submitted to the Codel Database.

When we receive that data, it is burned, immediately, onto a CDR and an entry is made in our own Master Document Table(MDT) which captures the hash value of the uploaded file, time-stamps it (using a Trusted Time-Server) and optionally captures source identifiers.

Only after that process has taken place is the data uploaded to our online database, where anyone can interrogate the data to establish the validity of one or more hashes.

One MDT is created for each CD. When the CD is full (or at the end of our own Audit Period - whichever comes first) the MDT is closed and itself burned on to the next CD and stored in our own Permanent Secure Audit Location.

Our own final step is submission of the hash value of each MDT to a number of reputable journals for publication in their classified section.
