Este artigo propõe um método esteganográfico baseado em DCT denominado StegErmelc no domínio JPEG. Três estratégias são propostas, a saber (i) seleção de bloco semelhante a borda, (ii) codificação de matriz recursiva e (iii) serviço de maior coeficiente, para formar um novo método esteganográfico para alcançar capacidade de portadora escalável, baixa detectabilidade por esteganalizador cego universal, e alta qualidade de imagem, simultaneamente. Para um determinado comprimento de mensagem, o StegErmelc dimensiona de forma flexível sua capacidade de portadora para acomodar a mensagem enquanto negocia com a detectabilidade do stego. Em plena capacidade, StegErmelc possui capacidade de transporte comparável em relação aos métodos existentes. Ao incorporar a mesma quantidade de informações, o StegErmelc reduz notavelmente a taxa de detecção de stego para cerca de 0.3-0.5 inferior à dos métodos existentes considerados e, consequentemente, o StegErmelc pode suportar o esteganalizador cego ao incorporar até 0.10 bpc. Nas mesmas condições, StegErmelc produz imagem stego com qualidade superior à dos métodos existentes considerados. A comparação gráfica com três métricas de avaliação adicionais também é apresentada para mostrar o desempenho relativo do StegErmelc em relação aos métodos existentes considerados.

Abstract: This paper proposes a DCT-based steganographic method named StegErmelc in the JPEG domain. Three strategies are proposed, namely (i) edge-like block selection, (ii) recursive matrix encoding, and (iii) largest coefficient serving, to form a novel steganographic method for achieving scalable carrier capacity, low detectability by universal blind steganalyzer, and high image quality, simultaneously. For a given message length, StegErmelc flexibly scales its carrier capacity to accommodate the message while trading off with stego detectability. At full capacity, StegErmelc has comparable carrier capacity relative to the existing methods. When embedding the same amount of information, StegErmelc remarkably reduces the stego detection rate to about 0.3-0.5 lower than that of the existing methods considered, and consequently StegErmelc can withstand blind steganalyzer when embedding up to 0.10 bpc. Under the same condition, StegErmelc produces stego image with quality higher than that of the existing methods considered. Graphical comparison with three additional evaluation metrics is also presented to show the relative performance of StegErmelc with respect to the existing methods considered.
