  • Server system 102 includes Postage servers
  • the Server system 102 is designed in such a way that all of the business transactions are processed in the servers and not in the database. By locating the transaction processing in the servers, increases in the number of transactions can be easily handled by adding additional servers. Also, each transaction processed in the servers is stateless, meaning the application does not remember the specific hardware device the last transaction utilized. Because of this stateless transaction design, multiple servers can be added to each appropriate subsystem in order to handle increased loads. Furthermore, each cryptographic module is a stateless device, meaning that a PSD package can be passed to any device because the application does not rely upon any information about what occurred with the previous PSD package.

If a Customer Support Representative (CSR) needs to verify identity, they can ask the user this question and the last four digits of their identification number (SSN, Tax ID or EID). Typically, lost password recovery can happen in three ways: On the phone with CS. through the client (requires adding a "Forgot my Password " to the login screen), or through e- mail with CS. In all these cases, the users will not get their actual password back. They will get a temporary "Reset Password' that is only good for one login.

Abstract

L'invention concerne un système d'impression en ligne d'articles portant une valeur (VBI) qui comprend un ou plusieurs modules cryptographiques et une base de données centrale. Les modules cryptographiques sont capables de mettre en application diverses normes de sécurité requises. Un système de client fournit une GUI conviviale servant à faciliter l'interface de l'utilisateur avec le système. Le système de GUI comprend des assistants qui aident l'utilisateur pas à pas dans les processus d'enregistrement, d'ouverture de session et d'impression des VBI. Dans un mode de réalisation, l'invention décrit un système en ligne servant à imprimer un VBI, qui comprend une mémoire pour stocker des informations spécifiques à un premier ordinateur utilisé par l'utilisateur pour s'enregistrer auprès du système en ligne. Les informations sont utilisées par le système de serveur pour identifier le premier ordinateur, et par un assistant de réenregistrement qui demande à l'utilisateur de se réenregistrer si celui-ci emploie un deuxième ordinateur, différent du premier ordinateur utilisé pour l'enregistrement.
