“…In this scenario, steganographic and watermarking schemes have the purpose of providing privacy and autenticity using information hiding fundamentals [4, 6, 7, Juliano B. Lima juliano bandeira@ieee.org 1 Department of Electronics and Systems, Federal University of Pernambuco, Av. da Arquitetura, S/N, 50740-550, Recife, Brazil 20,28]. On the other hand, multimedia encryption schemes employ several strategies and mathematical tools with the purpose of making perceptual and statistical aspects of an image or an audio file seem noisy [1,12,15,29,30].…”

In this paper, we introduce an audio encryption scheme based on the cosine number transform (CNT). The transform, which is defined over a finite field, is recursively applied to blocks of samples of a noncompressed digital audio signal. The blocks are selected using a simple overlapping rule, which provides diffusion of the ciphered data to all processed blocks. A secret-key is used to specify the number of times the transform is applied to each one of such blocks. Computer experiments are carried out and security aspects of the proposed scheme are discussed. Our analysis indicates that the method meets the main security requirements of secret-key cryptography. More specifically, after the encryption of 16-bit audio signals, correlation coefficients significantly close to 0 and entropy values close to 16 were obtained. Furthermore, the flexibility of the method easily allows key space sizes greater than 2 256 and provides robustness against differential, known-plaintext and chosen-plaintext attacks.

“…Steganografi kelime anlamı olarak gizli yazı veya örtülü yazı anlamına gelmekte olup bilginin varlığı tespit edilemeyecek şekilde saklanması sanatıdır [2]. Sayısal veri dosyası formatlarının çeşitliliği sayesinde birçok dosya türü içerisine steganografik yöntemlerle veri saklanabilmektedir [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Bunlardan [5] no'lu çalışmada resim, ses ve metin gibi dosya türleri içerisine veri saklama tekniklerini detaylı bir şekilde açıklanmıştır.…”

ÖZETBu makalede, steganografi tabanlı yeni bir kişisel güvenlik yaklaşımı sunulmuş ve pratik olarak kullanımı için ise bir klasör kilitleme yazılımı (STKK) geliştirilmiştir. Sunulan yaklaşım kullanıcılara, bilgisayardaki tüm dosyaların güvenliği için esnek ve güvenilir çözümler sunmaktadır. Steganografik çözümlerin yanı sıra AES, DES ve 3DES gibi bilinen kriptografik yaklaşımların da geliştirilen yazılıma eklenmesi ile güvenlik arttırılmıştır. Deneysel sonuçlar, geliştirilen çözümün steganalize karşı dayanıklı olduğunu ve tüm dosya tiplerini desteklediği için kişisel güvenliğin artırılmasına katkı sağlayacağını göstermektedir.Anahtar Kelimeler: Steganografi, steganaliz, güvenlik, klasör kilitleme yazılımı, kriptografi, DES, 3DES, AES DEVELOPMENT OF A NEW FOLDER LOCK APPRAOCH AND SOFTWARE BASED ON STEGANOGRAPHY ABSTRACTThis paper introduces a new personal security approach based on steganography. In order to achieve the task, a folder-lock software (STKK) was developed. The proposed approach provides more flexible solutions to the users to secure all files in the computer. In addition to steganographic solutions, cryptographic approaches such as AES, DES and 3DES are also added to the developed software. The experimental results have shown that the developed solution is robust against steganalysis and might provide better personel security by supporting all file types.

“…The most popular type of the audio file formats is WAV which is easy to be converted into samples, and MP3 which needs to be preprocessed until we are able to obtain the sample values [10]. Furthermore, WAV type is more guaranteed for obtaining the secret message.…”

“…The former directly uses and handles the value of the audio samples and directly embed the data such as LSB methods and difference expansion; while the latter, which is called frequency domain, converts the audio into another domain and then embeds the secret bits within that particular domain such as discrete wavelet transform (DWT). In [10,11], The obtained values from this DWT are used to hide the secret binary bits.…”

Audio Data Hiding Based on Sample Value Modification Using Modulus Function

Data hiding is a wide field that is helpful to secure network communications. It is common that many data hiding researchers consider improving and increasing many aspects such as capacity, stego file quality, or robustness. In this paper, we use an audio file as a cover and propose a reversible steganographic method that is modifying the sample values using modulus function in order to make the reminder of that particular value to be same as the secret bit that is needed to be embedded. In addition, we use a location map that locates these modified sample values. This is because in reversible data hiding it needs to exactly recover both the secret message and the original audio file from that stego file. The experimental results show that, this method (measured by correlation algorithm) is able to retrieve exactly the same secret message and audio file. Moreover, it has made a significant improvement in terms of the following: the capacity since each sample value is carrying a secret bit. The quality measured by peak signal-to-noise ratio (PSNR), signal-to-noise ratio (SNR), Pearson correlation coefficient (PCC), and Similarity Index Modulation (SIM). All of them have proven that the quality of the stego audio is relatively high.
