Audio steganography is an approach of hiding information within an audio signal. As data is embedded in the signal, it gets changed. This modification should be create indistinguishable to the human ear.Image can also be taken as a medium but audio steganography is more impressive because of the features of Human Auditory System (HAS) like large power, powerful range of hearing and high range of audible frequency.Cryptography includes the encryption of message. It creates no attempt to conceal the encrypted message. In steganography, the original message is not changed but the very continuation is secret from the intruder by embedding ... Read More

Steganography is the art of concealing the fact that connection is taking place, by hiding data in other information. Some different carrier file structure can be used, but digital images are the important because of their frequency on the computer network.For concealing private data in images, there exists a huge method of steganographic approaches some are more difficult than others and some have specific powerful and weak points.There are several applications have multiple requirements of the steganography methods used. For instance, there are some software can needed absolute invisibility of the hidden information, while others needed a higher secret message ... Read More

Least significant bit (LSB) insertion is a common and simple method to embed data in an image file. In this approach the LSB of a byte is restored with an M’s bit. This technique operate well for image steganography. For hiding data within the images, the LSB (Least Significant Byte) approach is generally used.An image file is a file that shows multiple colors and intensities of light on different location of an image. The best type of image files to hide data inside is a 24 Bit BMP (Bitmap) image.When an image is of large quality and resolution it is ... Read More

Steganography is not only the art of hiding information but also hiding the element of transmission of secret information. Steganography hides the secret information in another file in such a method that only the recipient understand the existence of message.In ancient time, the data was secured by hiding it on the back of wax, scripting tables, and stomach of rabbits or on the scalp of the slaves. But today’s there are some people transmit the information in the form of text, images, video, and audio over the medium.It can be securely transmission of confidential information, the multimedia objects such as ...

Image steganography has truly state-of-the-art with the invention of quick, dynamic computers. Software is simply accessible for processing and hiding of data images. Images can also be recovered very simply.There are three main methods of information hiding in images which are as follows −Least Significant Bit Insertion − This is the most famous image steganography technique. It is simple, easy to make and also simply to use. Unfortunately, it is intensely vulnerable to attack. A simple conversion of structure can damage all hidden data.The best approach of image document to hide data inside is a 24 Bit BMP (Bitmap) image. ... Read More

Images are the most famous cover objects used for steganography. In image steganography, pixel intensities are used to conceal the information. In the area of digital images, there are different image file formats exist, most of them for definite applications.An image is a set of numbers that constitute different light intensities in different location of the image. This numeric description forms a grid and the single points are defined as pixels. Most images on the Internet includes a rectangular map of the image’s pixels (defined as bits) where each pixel is situated and its colour. These pixels are shown horizontally ... Read More

There are various approaches of text steganography which are as follows −Line Shift − In this method, secret message is private by vertically changing the text lines to some degree. A line decided has two clear control lines one on side of it for identifying the direction of movement of the marked line. It can hide bit 0, a line is changed up and to hide bit 1, the line is changed down.Determination of whether the line has been changed up or down is completed by computing the distance of the centroid of apparent line and its control lines. If ... Read More

Steganography is the art and science of concealing a message within another message without drawing some suspicion to others so that the message can only be identified by its intended recipient.There are various techniques of text steganography which are as follows −Line-shift coding − Features are marked into the text by changing the lines, so as to create recognition harder. Text lines are vertically changed for encoding. This can be used to either a format file or to the bitmap of a page.By transforming each second line of the document 1/300th of an inch up or down, line-shift encrypting provide ... Read More

Text steganography is an approach of hiding secret text message within another text as a covering message or creating a cover message associated to the initial secret message.Text steganography can include anything from transforming the formatting of an existing text, to changing words within a text, to producing random character sequences or utilizing context-free grammars to make readable texts.Text steganography is held to be the trickiest because of deficiency of redundant data which is present in image, audio or a video file. The mechanism of text documents is identical with what it can identify, while in another types of documents ... Read More

Steganography is the art and science of connecting which hides the presence of the communication. The purpose of steganography is to convey a message to a receiver in such a method that the very presence of the message is indistinguishable by a third party.In the computer world, steganography means hiding secret messages in graphics, pictures, movie, or sound. At any cost, steganography secure from pirating copyrighted materials as well as aiding in unauthorized viewing.The advantage of steganography is to connect fast in an absolutely imperceptible aspect and to prevent drawing suspicion to the communication of a hidden record.Steganography hide the ...
