Abstract:
Techniques are described for securely managing double-entry account journals provided for use by clients such as businesses and other organizations. Clients may implement their own accounting systems, or other systems that model financial information, which may use the described techniques for maintaining account journals. The described techniques include receiving transaction requests that specify journal entries, and making those entries in the specified account journals. A cryptographic authentication tag is calculated for each journal entry, based on authentication keys of a forward-secure sequence of authentication keys. This allows a service to verify, in response to a client request, that the order of the entries has not been altered after creation of the entries. The transaction requests may be signed by the client and the signatures saved so that the service can also verify that the entries are as provided by the client.

Claim (Index 2):
The method of  claim 1 , wherein verifying the integrity of the first account journal comprises:\n receiving a third request to verify an authenticity of the second authentication tag; recalculating the second sequential key based at least in part on a root key; determining a third authentication tag of the third journal entry based at least in part on recalculating the second sequential key; and verifying that the third authentication tag matches the second authentication tag.
