More than a century after Twain wrote his comments, what we now label “fee-for-service” has, as Twain lamented, continued as the dominant payment model in health care. However, the march toward value-based payment has started to change the system, and far more dramatic changes are on the horizon. The Affordable Care Act and payment reform are transforming the system back to Twain’s “old time cu...

Payment systems are one of the key Financial Market Infrastructures (FMIs) and have showed remarkable progress over the past two decades. The first half of this chapter focuses on the evolutionary process of payment systems, starting with the Deferred Net Settlement (DNS) system and progressing to the RealTime Gross Settlement (RTGS) system. Subsequently, much more sophisticated payment systems...

The rapid transition to card payments has sparked a search for effective countermeasures to those who exploit card payment security vulnerabilities to commit payment fraud. A review of these vulnerabilities finds that they are tied together by an information-intensive payment approval system. Especially damaging are large data breaches, which are often the result of criminals gathering informat...

Mobile payment system has made it easy for people to do financial transaction. However, its security is still a concern. It needs to protect the data transferred between parties involved in the system. In this paper, we investigate the possibility use of elliptic curve cryptography to secure the data transferred in a payment system.

In this paper we analyze the security of the new Brazilian Payment System. No worrying vulnerabilities were found, but there are some issues that we believe need to be addressed more carefully. Some minor changes and directions for further development of the system are proposed, such as: specifying which random number generators can be used in the system and encrypting digital signatures to avo...
