Abstract

um método (100) implementado por computador e um sistema (1) para determinar metadados m para proteger um recurso digital controlado, tal como um software de computador, utilizando uma tabela de dispersão distribuída (13) e um livro-razão distribuído através de peer-to-peer (14). este é um blockchain, tal como o blockchain do bitcoin. o método inclui determinar (110) dados associados ao software de computador e determinar (120) um primeiro valor hash com base no software de computador. um segundo valor hash com base nos dados e no software de computador pode ser determinado (130). o método inclui, adicionalmente, enviar 140, através de uma rede de comunicações (5), os dados, o primeiro valor hash e o segundo valor hash a um registro para armazenamento em uma tabela de dispersão distribuída (13). o segundo valor hash pode ser uma chave de um par chave-valor. os dados e o primeiro valor hash podem ser um valor no par chave-valor. metadados (m) que são baseados no segundo valor hash podem ser determinados (150) para armazenamento no livro-razão distribuído através de peer-to-peer (14).
