“…There are many forms of steganography that have been used to hide a secret message .One of them is the usage of invisible ink which is unrelated to computer for hiding the secret messages by writing the message with clear ink and they can be seen only by other ink when applied on the another message .Invisible ink technique is limited use today [3]. Then concept come under steganography is the technique which is mainly used for businesses called watermarking.…”

Steganography is the practice of concealing a secret message inside of another message. It is a form of covert communication and can involve the use of any medium like a computer file, message, image, or video within the other file, message, image or video. It is not the same as cryptography where cryptography means secret writing and steganography which is not as popular as cryptography means covered writing. Many different file formats are often used but digital images or media files are the most popular due to their most-used on the web and the large size of media files. There exist many Steganography techniques for hiding secret information in images where some of them are more complex than others. Steganography works by changing bits of useless or used data in regular computer files such as graphics, sound, and text with bits of different and invisible information. Steganography technique refers to methods in which data hiding is performed directly on every hundredths or thousandths pixel value of cover image by replacing with corresponding to letter in the alphabet in such a way that the effect of message is not visible on the cover image and unnoticeable to someone. This paper is intended to illustrate the different steganography techniques and the purpose of techniques.

“…Chun-Hsiang and others found that LSB or the final bit in a stream affects the smallest change while the first bit of the stream has the largest influence on color selection. If the LSB of every bit stream were to be allocated for a hidden message, the resulting image file would appear unaltered [8].…”

Internet is a public channel and security issues, such as modification, interception and sniffing normally exist. Steganography is a common security technique that is utilized to solve or reduce those problems. A large number of methods is used for implementing steganography; as least significant bits (LSB), discrete cosine transform (DCT), discrete Fourier transform (DFT), Spread Spectrum coding and Perceptual Masking. This paper proposes a random and sequential LSB to embed the secret message inside the color image. The linear congruent generator (LCG) is a random generator that is used with LSB to hide a stream of bits in a bitmap image (cover image) to give a new image (stego-image) comparable to the cover image. Secret key for random LSB is a combination of four parameters (Seed, Multiplier, Noncommon factor, and Cycle length). The proposed method employees red, green or blue channel to hide the secret message. Selection of channel based on the modification rate for each channel. The minimum modified channel in cover image is utilized to embed the secret message. Results show that random LSB is better than Sequential LSB in term of visual effect while the worst in term of execution time. Random LSB satisfies sufficient security to secret message due to requirements for random function parameters in the extraction process.

“…In some interesting cases, we will show that the cover message can be devised to help interpretation of the genuine messages. Note that the idea of digital invisible ink data hiding is firstly revealed in [15] and then briefly exploited in [16] by the authors. In this paper, we thoroughly describe the motivation, implementations and experimental results of digital-invisible-ink data hiding.…”

A novel data-hiding methodology, denoted as digital invisible ink (DII), is proposed to implement secure steganography systems. Like the real-world invisible ink, secret messages will be correctly revealed only after the marked works undergo certain prenegotiated manipulations, such as lossy compression and processing. Different from conventional data-hiding schemes where content processing or compression operations are undesirable, distortions caused by prenegotiated manipulations in DII-based schemes are indispensable steps for revealing genuine secrets. The proposed scheme is carried out based on two important data-hiding schemes: spread-spectrum watermarking and frequency-domain quantization watermarking. In some application scenarios, the DII-based steganography system can provide plausible deniability and enhance the secrecy by taking cover with other messages. We show that DII-based schemes are indeed superior to existing plausibly deniable steganography approaches in many aspects. Moreover, potential security holes caused by deniable steganography systems are discussed.
