Abstract
A method of storing data relating to a batch of items, such as mail items, on a processor-based system in a secure fashion is described. The method comprises receiving data relating to a parameter of each item in the batch and cryptographically protecting the database using a crypto engine in a secure vault. In a preferred embodiment, the method comprises sending the received data for each item to the crypto engine in the vault, which is operable to produce a message authentication code based on the received data and to tag the received data with the message authentication code, writing the data tagged with the message authentication code to the openly accessible database, and repeating the aforementioned steps for each subsequent item in the batch. The parameter of each item may be a physical parameter of the items, such as their respective weights, or a rating parameter, such as a postage value or class.
