Propomos um método reversível de ocultação de dados (RDH) em imagens criptografadas compressíveis, chamadas de imagens de criptografia e compactação (EtC). O método proposto nos permite não apenas incorporar uma carga útil em imagens criptografadas, mas também compactar as imagens criptografadas que contêm a carga útil. Além disso, o método RDH proposto pode ser aplicado tanto a imagens simples quanto a imagens criptografadas, e a carga útil pode ser extraída de forma flexível no domínio criptografado ou a partir das imagens descriptografadas. Vários métodos RDH foram estudados no domínio criptografado, mas não são considerados ocultação de dados de dois domínios, e as imagens resultantes não podem ser compactadas usando padrões de codificação de imagem, como JPEG-LS e JPEG 2000. Em nosso experimento, o método proposto apresenta alto desempenho em termos de eficiência de compressão sem perdas usando JPEG-LS e JPEG 2000, capacidade de ocultação de dados e qualidade de imagem marcante.

Abstract: We propose a reversible data hiding (RDH) method in compressible encrypted images called the encryption-then-compression (EtC) images. The proposed method allows us to not only embed a payload in encrypted images but also compress the encrypted images containing the payload. In addition, the proposed RDH method can be applied to both plain images and encrypted ones, and the payload can be extracted flexibly in the encrypted domain or from the decrypted images. Various RDH methods have been studied in the encrypted domain, but they are not considered to be two-domain data hiding, and the resultant images cannot be compressed by using image coding standards, such as JPEG-LS and JPEG 2000. In our experiment, the proposed method shows high performance in terms of lossless compression efficiency by using JPEG-LS and JPEG 2000, data hiding capacity, and marked image quality.
