Abstract

SISTEMA E MéTODO PARA CODIFICAR RECURSOS DISTRIBUìDOS ALEATORIAMENTE EM UM OBJETO. Os sistemas e métodos descritos são orientados para a codificação de recursos aleatoriamente distribuídos em um objeto. Recursos aleatoriamente distribuídos em um objeto de autenticação são determinados. Dados representando os recursos aleatoriamente distribuidos são compactados e codificados com uma assinatura. Uma etiqueta é criada e inclui objeto de autenticação e os dados codificados. Os dados podem ser compactados mediante determinação de uma função de densidade de probalidade associada ao objeto de autenticação. Vetores associados aos atributos aleatoriamente distribuidos são determinados com base, pelo menos em parte, na função de densidade de probalidade. Os vetores são codificados utilizando um algoritmo de codificação aritmética.
