“…of LSBs (or bits) that would be modified during the embedding process of each technique is shown in the last column of the table. As can be observed in all the aforementioned LSB-based techniques; these were mainly focused on following steganography objectives, i.e., to increase the embedding capacity [8,10,[13][14][15], to enhance visual imperceptibility [13,15,18,23] and to improve security against detectability and hidden data [13,14,20,21]. However, we found tradeoffs among all these objectives because these are correlated to one another.…”

High-Capacity Image Steganography with Minimum Modified Bits Based on Data Mapping and LSB Substitution

Steganography is the art and practice of communication using hidden messages. The least significant bits (LSB) based method is the well-known type of steganography in the spatial domain. Usually, achieving the larger embedding capacity in LSB-based methods requires a large number of LSB bits modification which indirectly reduces the visual quality of stego-image and increases the risk of steganalysis detection attacks. In this study, we propose a novel steganography method with data mapping strategy which can reduce the number of bits modification per pixel. In the proposed method, four secret data bits are mapped with the four most significant bits of a cover pixel. Furthermore, the only two LSBs of a pixel are modified to indicate the mapping strategy. Experimental results show that the proposed method is able to achieve 3.48% larger embedding capacity while enhancing the visual quality (i.e., peak signal to noise ratio (PSNR) 3.73 dB) and reducing the modification of 0.76 bits per pixel. Moreover, the proposed method provides security against basic Regular and Singular groups (RS) steganalysis and histogram steganalysis detection attacks.

“…Usually, in LSB-based methods, the secret data bits are substituted in k-least significant bits of each pixel. In the literature, various types of LSB-based techniques have been proposed [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] targeted at high capacity, visual quality and security.…”

Perkembangan Internet dan aplikasi berbasis jaringan telah menjangkau ke berbagai macam aplikasi yang memungkinkan seseorang untuk saling berkirim pesan dan informasi tanpa dibatasi jarak dan waktu. Seiring dengan perkembangan itu pula, kerentanan akan aspek keamanan sebuah system juga semakin meningkat. Dalam penelitian ini, peneliti mencoba menerapkan kombinasi antara metode kriptografi dan steganografi yang bertujuan untuk meningkatkan upaya pengamanan sebuah pesan. Kriptografi Cipher Block Chaining (CBC) merupakan kriptografi yang sudah umum digunakan contohnya pada protocol internet TLS dan IPsec. Proses enkripsi dan dekripsi CBC memerlukan waktu yang relatif singkat karena mode CBC memiliki kecepatan dan efisiensi lebih tinggi dan dinilai lebih mudah diimplementasikan. Metode berikutnya yang digunakan adalah Steganografi Least Significant Bit (LSB) yang bekerja secara sederhana namun sangat efektif dalam menyisipkan pesan tersembunyi. Namun, beberapa penelitian menemukan kelemahan LSB yang dapat menemukan keberadaan pesan tersembunyi menggunakan algoritma steganalytic pada tingkat embedding yang rendah. Untuk itu, LSB harus dikembangkan lagi dengan menerapkan deteksi tepi sobel yang dapat bekerja untuk mendeteksi keypoint penyembunyian pesan sehingga LSB tidak lagi bekerja secara standar. Kombinasi metode CBC dan LSB-Sobel telah terbukti dan berhasil merahasiakan pesan dengan baik dan menghasilkan stego-image yang berkualitas tinggi setelah dilakukan pengujian PSNR dan MSE. Kata kunci: Kriptografi, steganografi, CBC, LSB, Deteksi Tepi Sobel

“…An interesting example of how to deal with the Chi square [13] and LSB enhancement attack in the LSB method we can find in Reference [14]. And finally hybrid Canny-Sobel edge detection was used by Setiadi [15]. We find these methods to be one of the most interesting.…”

Our concern in this paper is to explore the possibility of using rough inclusions for image steganography. We present our initial research using indiscernibility relation as a steganographic key for hiding information into the stego carrier by means of a fixed mask. The information can be embedded into the stego-carrier in a semi-random way, whereas the reconstruction is performed in a deterministic way. The information shall be placed in selected bytes, which are indiscernible with the mask to a fixed degree. The bits indiscernible with other ratios (smaller or greater) form random gaps that lead to somehow unpredictable hiding of information presence. We assume that in our technique it can modify bits, the change of which does not cause a visual modification detectable by human sight, so we do not limit ourselves to the least significant bit. The only assumption is that we do not use the position when the mask we define uses it. For simplicity’s sake, in this work we present its operation, features, using the Least Significant Bit (LSB) method. In the experimental part, we have implemented our method in the context of hiding image into the image. The LSB technique in its simplest form is not resistant to stegoanalisys, so we used the well-known LSB matching method to mask the presence of our steganographic key usage. To verify the resistance to stegoanalisys we have conducted and discussed Chi-square and LSB enhancement test. The positive features of our method include its simplicity and speed, to decode a message we need to hide, or pass to another channel, a several-bit mask, degree of indiscernibility and size of the hidden file. We hope that our method will find application in the art of creating steganographic keys.
