Secure and recoverable database for on-line value-bearing item system
First Claim
1. An on-line system for printing value bearing items (VBI) comprising:
- a server sub-system configured to communicate with a plurality of users over a communication network, the server sub-system comprising;
a secure database subsystem remote from the users and including a data record for each of the users, wherein each data record is protected by a key; and
a plurality of stateless cryptographic devices, each of the plurality of stateless cryptographic devices configured to perform authentication, processing value for the VBI, and generation of indicia data for the plurality of users, wherein before each of the authentication, processing value, and generation of indicia data for a given user is performed, an available cryptographic device in the server sub-system and the secure database subsystem cross-verify a previous data record transaction before proceeding with the authentication, processing value, and generation of indicia data for the given user, and wherein after the authentication, processing value, and generation of indicia data for the given user are performed, a printer is instructed to print the VBI.

Abstract
An on-line value bearing item (VBI) printing system that includes one or more cryptographic modules and a secure database is disclosed. The secure database includes account balances and other information for all of the on-line value-bearing item system customers and is capable of preventing access by unauthorized users. Also, a secure communication network is in operation to prevent unauthorized access to the users'"'"' data stored in the database.
A plurality of subsystems located on the server system side of the on-line VBI system provide services related to purchasing, accounting, and printing of VBI. In addition to the secure database, the server system includes one or more cryptographic modules for authenticating, processing value for the VBI, and generating indicia data for the plurality of users.
