Abstract

Patente de Invenção: "MéTODO PARA GARANTIR A SEGURANçA DE INFORMAçõES ELETRôNICAS". Uma técnica de garantia de segurança para as informações eletrônicas em que um arquivo de informações eletrônicas 1 é dividido em uma pluralidade de elementos de informação 2 e os elementos de informação divididos são selecionados e combinados com a sua ordem trocada para produzir um ou mais blocos de informações 3, e os dados de extração de divisão são produzidos e os blocos de informações são formados e armazenados ou transmitidos, após o que, quando as informações eletrônicas estão para ser utilizadas, os elementos de informação 4 incluídos nos blocos de informações 3 são redivididos, redispostos na ordem correta e integrados baseado nos dados de extração de divisão para restaurar um arquivo de informações eletrônicas original 5, por meio de que, mesmo se as informações eletrônicas armazenadas ou que estão sendo comunicadas forem roubadas, o valor das informações é reduzido para impedir a utilização das informações.
