gnotary

Gnotary will prove the integrity and authenticity of your electronic health records by countersigning a digital signature of your document (with optional offsite storage, where you have no access). The client will provide a GUI for selecting files for a backup, calculating strong hashes for each file, and storing files in a compressed ZIP archive file. By pressing a single button, the hashes of the selected files are calculated and sent to one or more notary servers.

The server will grab incoming mail that matches a filter condition, pipe it through the GNU privacy guard signing process, retain a copy of the signed message, and return the signed message to the sender. In the future, all notary servers will exchange message digests of their own certificate log mutually (and get them mutually certified), thus creating a virtually unbreakable chain of evidence (tampering with one certificate invalidates all others in an auditable way).

The project is in an early beta stage; no official releases have been made. The current code can be downloaded from Savannah, the GNU CVS repository.
