Segurança em Sistemas de Micropagamentos Eletrônicos
Abstract
Cryptography is used to offer security and also to generate electronic currency for electronic commerce applications over the Internet, especially for those using micropayment schemes. In such schemes, payments involving very low amounts are done quickly and frequently. An important aspect of electronic commerce systems with on-line distribution of goods is that value and goods transferences must be atomic transactions. In such systems, forward and backward error recovery are combined to prevent fraud. PayPerClick is a tool for electronic sale and on-line distribution of publications based on micropayments.
