“…There are following types of steganography according to a medium that is used to hide data: Text, Audio, Video, and Image. Changder et al (2009) have presented a novel approach for Indian text steganography. In this technique, perceivable sentences are formed to hide the obscure message.…”

Steganography is used for invisible secured communication. In this technique, information is hidden on different medium like audio, video, text, or images by using different approaches or algorithms. This research has developed a novel steganography technique which combines grayscale image segmentation and least significant bit (LSB) substitution methods to hide information. In the proposed technique the cover image is segmented in a different number of blocks. Each block hides just one bit of information in its LSB. The number of blocks is directly proportional to the size of the information in bits. In such a way, information is hidden in the whole image, not in a specific area of an image, so there is no image degradation.

Steganography can be defined as a method of hiding data within a cover media so that other individuals fail to realize their existence. Steganographic systems play a vital role in covertly transmission of information even in the presence of an arbiter The message can be hidden in images, audio files or in text. Although the embedded message changes the characteristics and nature of the document in which it is hidden, it is required that these changes are difficult to be identified. The difference in the pixel values can be used for hiding the information. To enlarge the capacity of the hidden secret information and to provide an imperceptible stego-image for human vision, a novel steganographic approach using five pixel pair differencing (FPPD) is proposed in this paper. Experimental results shows that the proposed algorithm provides increased capacity of message hiding along with better quality of stego images.

“…To secure one to one communication, steganography is an important technique [3], the principle is that the third party must not have a hint of what is being transferred, Steganography enables information transfer in a covert manner such that it does not draw the attention of the unintended recipients [4]. The cover image is used to carry the secret message, because the human eyes are insensitive to very minute changes to the colours and hence, intelligently embeds the data and transmits it to the receiver [4][5][6]. When received, the data is securely retrieved by extraction.…”

“…Both Steganography and Cryptography are excellent means by which to accomplish this but neither technology alone is perfect and both can be broken. It is for this reason that most experts would suggest using both to add multiple layers of security [4].…”

Recent advances in steganography systems have shown good results in bringing reliable data security over the internet. However' these systems have their unique vulnerabilities since they are faced with a variety of threats from attackers. Effective steganography systems must be able to conceal hidden data completely as if there were nothing hidden on them. That is, they must be undetectable to steganalysis procedures from unauthorized individuals. This work proposes a secure multi-level steganography system to safeguard data transmission and sharing over the Internet wherein cryptographic and steganographic techniques are combined. It also proposes compressing the cipher-text file using the Lempel-Ziv algorithm to reduce its size so that it uses less space in the cover image after data embedding. In this work, the use of Discrete Cosine Transform and Inverse Discrete Cosine Transform for Image processing is explained, since they will be used in the process of image compression and decompression respectively.
