Makalah ini mencadangkan skema penyembunyian data mesra sistem penyulitan-kemudian-mampatan (EtC) untuk imej, di mana sistem EtC memampatkan imej selepas ia disulitkan. Sistem EtC membahagikan imej kepada blok tidak bertindih dan menggunakan empat proses berasaskan blok secara bebas dan rawak pada imej untuk penyulitan visual imej. Skim yang dicadangkan menyembunyikan data kepada yang biasa, iaitu, imej tidak disulitkan dan skema boleh mengeluarkan data tersembunyi daripada imej yang disulitkan oleh sistem EtC. Tambahan pula, skim ini menyediakan penyembunyian data boleh balik, jadi ia boleh memulihkan imej yang tidak ditanda dengan sempurna daripada imej yang ditanda manakala skema itu sekali memesongkan imej yang tidak ditanda untuk menyembunyikan data kepada imej. Skim yang dicadangkan mengatasi tiga daripada empat proses dalam sistem EtC, iaitu, pilih atur blok, putaran/terbalikan blok, dan kecerahan penyongsangan dalam blok, manakala skema konvensional untuk sistem tidak mengatasi yang terakhir. Di samping itu, skim konvensional ini perlu mengenal pasti imej yang disulitkan supaya maklumat sisi yang bergantung kepada imej boleh digunakan untuk mengekstrak data terbenam dan untuk memulihkan imej yang tidak ditanda, tetapi skema yang dicadangkan tidak memerlukan pengenalan sedemikian. Selain itu, walaupun proses penyembunyian data mesti mengetahui saiz blok penyulitan dalam skim konvensional, skim yang dicadangkan tidak memerlukan pengetahuan awal tentang saiz blok untuk penyulitan. Keputusan eksperimen menunjukkan keberkesanan skim yang dicadangkan.

Abstract: This paper proposes an encryption-then-compression (EtC) system-friendly data hiding scheme for images, where an EtC system compresses images after they are encrypted. The EtC system divides an image into non-overlapping blocks and applies four block-based processes independently and randomly to the image for visual encryption of the image. The proposed scheme hides data to a plain, i.e., unencrypted image and the scheme can take hidden data out from the image encrypted by the EtC system. Furthermore, the scheme serves reversible data hiding, so it can perfectly recover the unmarked image from the marked image whereas the scheme once distorts unmarked image for hiding data to the image. The proposed scheme copes with the three of four processes in the EtC system, namely, block permutation, rotation/flipping of blocks, and inverting brightness in blocks, whereas the conventional schemes for the system do not cope with the last one. In addition, these conventional schemes have to identify the encrypted image so that image-dependent side information can be used to extract embedded data and to restore the unmarked image, but the proposed scheme does not need such identification. Moreover, whereas the data hiding process must know the block size of encryption in conventional schemes, the proposed scheme needs no prior knowledge of the block size for encryption. Experimental results show the effectiveness of the proposed scheme.
