Abstract

sistemas, métodos e programas de computador são apresentados para a detecção de uma funcionalidade de alto nível de uma aplicação que executa em um dispositivo de computação. um método compreende armazenar, em uma memória segura em um dispositivo de computação, uma tabela de mapeamento de endereços virtuais para uma aplicação. a tabela de mapeamento de endereços virtuais compreende uma pluralidade de endereços virtuais no código binário de aplicação mapeado para funcionalidades de aplicação alvo correspondentes. a aplicação é registrada com um sistema operacional de alto nível (hlos). durante a execução do código binário de aplicação, o hlos detecta quando um ou mais dos endereços virtuais correspondentes às funcionalidades de aplicação alvo são executados com base na tabela de mapeamento de endereços virtuais.
