“…In [15] author presented a steganography approach based on DWT in which more than one secret image are embedded in one cover image. In [16], presented high capacity LSB based steganography utilizing distributed approach making stego-images stronger against several steganalysis attacks as decomposed secret information are equitably distributed among various cover images file making it harder to decide its reality, however this approach does not use appropriate scheme to reassemble circulated images.…”

This paper presents a framework that conceal large volume of secret information using distributed file system that permit implantation of decomposed secret images across multiple-cover images. The strong security is imposed utilizing Shamir’s threshold scheme and permutation generator framework. Three layers of security is being applied to protect the secret information, in first, secret image is decomposed into equal size of smaller sub-images and generate a framework of permutations from an integer for distributing and reassembling the circulated broken secret sub images among the intended participants. At the time of embedding purpose of permutation generator is to arrange the sub-images in unknown order for outsider. During the discloser stage only inverse of permutation can rearrange the distributed sub-images to reassemble into original image by authorized contributors. In second, Shamir’s threshold scheme is designed for authentication of shared associated stego-cover images before starting the extraction process. This process provides an extremely secured construction of shared secret information. In third, image is divided in 2x2 blocks of pixels and traverses it in zig-zag manner; the pixel value difference is computed for all Red, Green, and Blue (RGB) components between non-overlapping pixels of selected diagonal path with in targeted block. Secret bits are concealed inside RGB color pixels of cover image by utilizing proposed novel pixel-value differencing (PVD) scheme, furthermore varying embedding capacity may be obtained by controlling the selection of number of 2x2 block. Exploratory result displays that the proposed approach provides productive algorithms in term multilayer unbreakable security and higher payload of embedded information.

In this paper, we have proposed an approach of PDF based text Steganography by considering the hiding capacity and security of secret information, and improved imperceptibility of stego-cover file. In proposed approach secret information are transformed into compact and encrypted form of imperceptible coding, and then translated into bits form, thereafter embedded into targeted locations of PDF file by applying new cross-reference coding technique in incremental updates of PDF file with less computation complexity. The proposed extraction process provides authentication of received stego-cover file such that only desired file is accepted for the extraction process otherwise fake file is discarded by recipient. Time complexity has been improved significantly by implementing a novel method of PDF steganography for embedding the secret data. Experimental result demonstrates that proposed method provides efficient algorithms in terms of improved security of hidden information.

“…Cryptography has its own significance to protect the secret information by making nonunderstandable, on the other hand, its weakness is encryption information can make the suspicious about its privacy and can be tempered by the third party though preferred standpoint of steganography is, it protects the secret information by embedding it into another digital file thus making the secret information imperceptible so there is less probability of susceptibility. Steganography is a developing research field keeping in mind the goal to provide state-of-the-art development of information security framework [1].…”

In this paper, a novel approach of PDF-based text steganography is presented. A covert communication is achieved by embedding secret information at between-characters positions of words within cover PDF text. A stegoencoding technique is being designed to improve the embedding capacity along with sufficiently reduced overheads of stego-cover PDF file. The proposed method constructs multilevel embedding capacities which can be used according to requirements from higher embedding capacity to typical embedding capacity. Encoding and decoding of secret text is being obtained by implementing quadratic probing of hashing technique that builds up a direct encoding table which provides better performance in term of time complexity. Exploratory outcome exhibits that the proposed technique gives productive algorithms in term upgraded security and high payload of concealed data. Experiential verification and examination of the proposed technique with certain prominent text steganographic techniques demonstrate that proposed technique performs better than current methodologies and free of requirements like shading scheme, languages, wordlist, compression and so forth.
