Abstract
SISTEMA E MéTODO PARA OCULTAR DADOS REVERSìVEIS ROBUSTOS E RECUPERAçãO DE DADOS NO DOMìNIO ESPACIAL. Um método incluindo identificar pelo menos dois subconjuntos de pixels dentro de um bloco de uma imagem; formar uma pluralidade de grupos de pixel dos pelo menos dois subconjuntos de pixel, cada grupo de pixel tendo pelo menos um pixel de um primeiro dos pelo menos dois subconjuntos e pelo menos um pixel de um segundo dos pelo menos dois subconjuntos; produzir uma pluralidade de valores de diferença, cada grupo de pixel provendo um dos ditos valores de diferença, cada valor de diferença sendo baseado nas diferenças entre valores de pixel dos pixels dentro de um dos grupos de pixel e modificar os valores de pixel dos pixels em menos do que todos dos pelo menos dois subconjuntos, dessa maneira embutindo um valor de bit no bloco.
