Transactional data transfer in a network system

摘要

An internet user using a browser (10) connects to a first server (30) and conducts transactions at the site (30). The user is transferred to a second server (32) along with data relating to the transactions via the user's browser program (10). A digital signature is added to the data prior to transfer. Before the user can access the second server (32), the digital signature is verified, thus promoting security and integrity of the transaction.
