Abstract

NetBill is a system for micropayments for information goods on the Internet. This paper presents the NetBill protocol and describes its security and transactional features. Among our key innovations are: • An atomic certified delivery method so that a customer pays if and only if she receives her information goods intact. • Outsourcing access control: different users can use different access control servers. • A credential mechanism allowing users to prove membership in groups. This supports discounts. • A structure for constructing pseudonyms to protect the identities of consumers.
