Abstract

''MéTODO E SISTEMA PARA IMPEDIR O ACESSO NãO AUTORIZADO A UM PROGRAMA DE COMPUTADOR''. Trata-se de um sistema e método para impedir que um programa seja rodado sob um programa utilitário de eliminação de bugs. O método faz parte de uma rotina que é armazenada junto com um programa de software em um disco rígido de um sistema de computador. O sistema de computador tem um processador para rodar tanto o programa de software quanto a rotina, e é capaz de operar em um modo de eliminação de bugs. A rotina impede o acesso não autorizado ao programa de computador, tal como quando o processador estiver rodando no modo de eliminação de bugs. Quando o processador estiver rodando o programa de software, o programa pode iniciar a execução da rotina. Uma vez iniciada, a rotina verifica um determinado registro do processador, para determinar se ele está operando no modo de eliminação de bugs e, caso esteja, impede que o processador continue a rodar o programa de software.
