Usando o encadeamento de transações para implementar um controle fim-a-fim de fraudes em aplicações distribuídas.

Abstract

This work presents an algorithm that can be incorporated into the application layer for detection of frauds in distributed applications that deal with electronic transactions. Based in a simple concept and easy implementation, the chaining of transactions allows the detection of frauds of both internal and external origin, even after the processing of the transaction. The use of this accessory mechanism in the end-to-end layer to complement other security mechanisms that may be adopted by the application also propitiates additional gains in the prevention of frauds and in the level of fault tolerance of the system. An example application is used to demonstrate the applicability of the algorithm and to improve the understanding of the concepts and techniques.
