Title: Jelte Van Der Hoek: Innovator in Transaction Card Systems
Introduction
Jelte Van Der Hoek is a notable inventor based in Amsterdam, Netherlands. He has made significant contributions to the field of transaction card systems, holding 2 patents that showcase his innovative approach to secure financial transactions.
Latest Patents
One of his latest patents is a multi-purpose transaction card system. This system comprises an issuer, one or more cards, one or more terminals, and optionally one or more acquirers. It utilizes a variety of cryptographic confidentiality and authentication methods. The cards authenticate messages using public key-based cryptography without performing the extensive computations usually associated with such cryptography. The integrity of complex transaction sequences and plural card storage updates is maintained, even under intentionally generated interruptions and/or modifications of data transmitted between the card and terminal. Importantly, the cards do not reveal any information to the terminal that is not directly necessary for the transaction or any information to which the terminal should not have access, though externally measurable aspects of its behavior are observable. The transaction types supported include those suitable for offline credit cards, in which the "open to buy" is maintained on the card.
