Esteganografia e Esteganálise: transmissão e detecção de informações ocultas em imagens digitais

Teoria e implementação da técnica de Esteganografia de imagens baseada 
nos bits menos significativos (LSB), que visa embutir dados em imagens 
digitais, e das técnicas de Esteganálise (estrutural, visual e 
estatística), que consistem na busca de padrões que permitam identificar
 a existência informações ocultas nas imagens suspeitas.
