Abstract

<B>INTERVENçãO AUTOMATIZADA E SELETIVA EM REDES BASEADAS EM TRANSAçãO<D> Perdas causadas por fraude em uma rede de comunicação são substancialmente reduzidas através da ação de invocar automática e seletivamente uma ou mais medidas de autenticação com base em um escore de fraude que indica a probabilidade de fraude para aquela chamada específica ou chamadas marcadas anteriormente. Através da invocação seletiva da autenticação apenas naquelas chamadas suspeitas ou que foram confirmadas como sendo fraudulentas, a prevenção de fraude pode ser conseguida de uma forma que reduza as perdas causadas por fraude e minimize as interrupções para assinantes legítimos. Utilizando com exemplo a fraude de telecomunicações, um assinante é registrado em um sistema através da coleta de dados sobre ele, com base no método de autenticação específico usado, tal como conhecimento partilhado (por exemplo, senhas), validação biométrica (por exemplo, verificação de voz) e semelhantes. Quando registrada, a função de autenticação para a conta do assinante é ativada e chamadas subseq³entes são então marcadas para a probabilidade de fraude durante a fase de solicitação de estabelecimento de chamada. A marcação de fraude avalia a probabilidade de fraude para cada chamada com base no comportamento aprendido de um assinante individual e no comportamento aprendido de perpetradores de fraude. Se não se suspeitar de fraude com base no escore, então o processamento normal de chamada pode ser recomeçado sem a necessidade de autenticação. Caso se suspeite de fraude com base no escore, então o sistema invoca automaticamente a autenticação. Se a autenticação indicar suspeita de fraude, por exemplo, gravações de voz não combinam, então a chamada pode ser bloqueada ou encaminhada para outras medidas de prevenção apropriadas, por exemplo, interceptadas por um operador. Se a fraude não for indicada pela autenticação, então o processamento de chamada normal pode ser recomeçado.
